Typification of Linnaean Datura names (Solanaceae)

The typification of six Linnaean Datura names ( D. stramonium, D. metel, D. arborea, D. ferox, D. fastuosa and D. tatuld ) is discussed. A modification to the typification of D.fastuosa is proposed and a lectotype for D. tatula is designated here.     

Typification of Brassica oleracea L. (Gruciferae) and its Linnaean varieties

OOST, E. H., BRANDENBURG, W. A. & JARVIS, C. E., 1989. Typification of Brassica oleracea L. (Cruciferae) and its Linnaean varieties. The Linnaean concept of Brassica oleracea and its varieties is discussed. In the light of this concept several types are considered and chosen.     

Typification of the name Thymus serpyllum L. (Lamiaceae)

Lectotypification of the name Thymus serpyllum L. (Lamiaceae) is presented. The name is typified by a specimen from the Burser herbarium (UPS), the only one which corresponds well with the present concept of T serpyllum and undoubtedly represents original material.     

Typification of the Linnaean names in Pyrola (Ericaceae,Pyroloideae)

Lectotypes are designated for four of the six Linnaean names inPyrola. The names are applied now to species ofChimaphila, Moneses, Orthilia, andPyrola (Ericaceae, Pyroloideae).     

Typifications of Linnaean names in the genus Centaurea and Serratula (Asteraceae)

The typification of three Linnaean names in the genus Centaurea and one in Serratula (Asteraceae): C. lippii (syn. Volutaria lippii), C. muricata (Volutaria muricata), C. repens (Rhaponticum repens) and S. babylonica (Centaurea babylonica), is discussed. Designations of nomenclatural types based on the consultation of Linnaeus's original material and the literature cited in the respective protologues are proposed. Three names are lectotypified using specimens from both Linnaeus herbarium at LINN and the illustrations from Isnard and Dodoëns. Furthermore, a neotype is designated for Serratula babylonica from a specimen at LINN.     

The biology and systematics of the genus Coincya Porta & Rigo ex Rouy (Cruciferae)

In this treatment, the genera Coincya (synonym: Hutera ) and Rhynchosinapis are regarded as one genus under the name Coincya which has nomenclatural priority. This study is based on data from morphology, population studies, cytology, ecology and reproductive biology reinforced by breeding experiments. Coincya is a west European genus comprising 14 taxa (including six species, five subspecies and three varieties).Eight new combinations are proposed and two species are excluded; R.nivalis is referable to the genus Brassica and R. Leplocarpa is probably referable to Erucastrum.
The chromosome number is either 2 n = 24 or 2 n = 48, which confirmed previous counts; C. Transtagana has not been counted. Breeding experiments were carried out with C. Longirostra, C.rupestris, C.monensis subsp. monensis , diploid and tetraploid races of subsp. recurvata var. recurvata , var. johnslonii , var. setigera , var. granatensis , subsp. hispida and subsp. puberula.
All taxa tested are outbreeding with a genetic self-incompatibility mechanism and are cross-compatible, suggesting that there has been no cytological differentiation between the diploid species in this study. The tetraploids formed semi-sterile triploids when crossed with diploids and although the chromosomes only formed bivalents and trivalents at meiosis it was postulated that the tetraploid was an autotetraploid of polytopic origin.
The evolution and differentiation of the genus and species are discussed.     

Typification of four species names of Bellis (Compositae)

There are six species of Bellis inhabiting the Iberian Peninsula, four of their accepted names are typified here. Bellis microcephala Lange, B. perennis L., and B. cordifolia (Kunze) Willk. are lectotypified, while an epitype is designated for B. sylvestris Cirillo. Some diagnostic characters are discussed in order to provide a proper identification of the specimens designated as types.     

Typification of names in Cyperus section Arenarii (Cyperaceae)

The typification of names in the genus Cyperus was done as part of an ongoing study of the section Arenarii. The latest monograph on the genus by Kükenthal (1936), accepted eight species in the section Bobartia (= Arenarii ), and a number of lower level taxa, which are treated here either as distinct species or synonyms. The taxonomic treatment of the core species, C. conglomerates Rottb., turned out to be especially confusing, which is reflected in the past identifications of the material, and consequently, has created wrong interpretations on the distributions. C. jeminicus Rottb. has similarly caused a lot of confusion. Currently we recognize 26 species in the section, with two subspecies in C. conglomerate. Most names in the section have not earlier been typified. Here we designate lectotypes for 33 names, three epitypes, and one neotype. Cyperus sections Arenarii Kunth and Hymenolepides Nees are typified also.     

Studies in the genus Physaria (Cruciferae)

Building upon a taxonomic treatment ofPhysaria published in 1939, an extension of information concerning the genus is presented. Comments on misapplication of the nameP. acutifolia Rydb., a new trichome type forPhysaria, and a high elevation species in Colorado are accompanied by the presentation of four new taxa. These areP. alpina, P. eburniflora, P. lepidota, andP. newberryi var.racemosa.     

Typification of the Linnaean name Ononis crispa and the related O. zschackei (Fabaceae)

The typification of the Linnaean name Ononis crispa and the related O. zschackei (Fabaceae) is discussed. Original material for O. crispa was traced at LINN, but found to be heterogeneous. In addition, the illustration by Magnol cited in the protologue represents O. aragonensis. The name is lectotypified using a specimen at LINN to preserve the current usage of the name and to avoid any ambiguity in the interpretation of the lectotype, an epitype is selected. Since no original material is extant for the name O. zschackei, a neotype is designated from a specimen preserved at P and collected in Mallorca (Balearic Islands, Spain).     

Typification of the Boissier names in Anthriscus Pers. (Apiaceae)

Boissier described several taxa in Anthriscus , summarized in his Flora orientalis account. The names include A. lamprocarpa, A. kotschyi, A. ruprechtii, A. tenerrima, A. t. var. leiocarpa, A. anatolica, A. macrocarpa, A. nemorosa var. mollis, A. n. var. glabra; the hst four are still recognized as separate species. These names are typified in this paper, based on the material in Boissier herbarium at G.     

Typification of three names in Antirrhinum (Plantaginaceae: Antirrhineae)

Typification of the names Antirrhinum barrelieri Boreau, A. controversum Pau and A. litigiosum Pau (Antirrhineae, Plantaginaceae) is needed to clarify the use and concept of these three names. The origin of a misinterpretation of the name A. barrelieri, which conditioned the subsequent use of these three names, is discussed. The previous ‘lectotype’ of A. barrelieri designated by Rothmaler from a Barrelier's illustration is shown to be ineffective, being contrary to Art. 9.12 of the ICN, and therefore a lectotype is designated from a syntype preserved in the herbarium of the Muséum des sciences naturelles d'Angers (France) at ANG. The Pau's names A. controversum and A. litigiosum have not been typified before, and lectotypes are here designated from specimens preserved at P and MA, respectively. As a consequence, the name A. litigiosum should be treated as a later heterotypic synonym of A. barrelieri.     

Chemosystematic studies on certain species of the family Brassicaceae (Cruciferae) in Egypt

The flavonoids of nine selected species belonging to different tribes of family Brassicaceae (Cruciferae) native to Egypt were surveyed, viz. Rorippa palustris, Coronopus squamatus, Eremobium aegyptiacum, Moricandia nitens, Brassica tournefortii, Farsetia aegyptia, Matthiola livida, Anastatica hierochuntica and Sisymbrium irio. Thirty-eight compounds were isolated and identified, which included six flavonol aglycones, 24 flavonol glycosides including 14 flavonol 3,7-diglycosides, one flavone aglycone, three flavone O–glycosides, two glycoflavones and two dihydroflavonoids. A numerical analysis based on a combination of 97 morphological, anatomical and chemical characters revealed two series, two subseries, two clusters and two groups. The interrelationships between the studied species are discussed.     

Lectotypification of Linnaean names for Flora Nordica (Brassicaceae - Apiaceae)

Linnaean names appearing in Flora Nordica in the families Brassicaceae - Apiaceae (in the conventional family sequence of the Flora) are typified. The main sources for types are the Linnaean Herbarium (LINN), the Clifford Herbarium (BM), the Burser Herbarium (UPS) and the Iter lapponicum herbarium in Paris (LAPP), and cited illustrations. The study forms part of the "Linnaean Plant Name Typification Project" based at The Natural History Museum, London (BM). - Flora Nordica notes No. 31.     

On the Chinese genus Solms-Laubachia Muschler (Cruciferae)

The genus Solms-Laubachia of Cruciferae was established by Muschler in 1912 on the basis of the Chinese species Solms-Laubachia pulcherrima of Yunnan Province. Since then, nine species, two varieties and two forms have been recorded. They are almost all endemic in China except one species—Solms-Laubachia retropilosa Botsch. which was discovered in Sikkim. We described in this paper thirteen species, three varieties and one form, of which, we suppose, three species, one variety and one combination have never been reported before. Most species grow in the mountainous regions of Szechuan, Yunnan, Tibet,Ching-hai and Sinkiang in China.     

Typification of Radlkofer's infrageneric names in Paullinia L. (Sapindaceae)

Ancillary to my revision ofPaullinia, the necessary lectotypifications for Radlkofer's infrageneric names are proposed. Those sectional names requiring lectotypification areNeurotoechus, Diphtherotoechus, Pleurotoechus, Pachytoechus, Xyloptilon, Neuroptilon, Anisoptilon, Isoptilon, Caloptilon, andPhygoptilon. SectionCryptoptilon, monotypic at the time of publication, is typified automatically byP. verrucosa Radlk. The generic namesEnourea andCastanella, reduced by Radlkofer to sectional status, retain their types.     

Lectotypification of the Linnaean names Thalictrum angustifolium and T. lucidum (Ranunculaceae)

Two further Linnaean names of Thalictrum are lectotypified. Thalictrum lucidum has priority over angustifolium. — Flora Nordica Notes no. 30.     

Typification of five names in Paracaryum (DC.) Boiss. (Boraginaceae)

Five names in the genus Paracaryum (DC.) Boiss. are lectotypified here: P. calycinum Boiss. & Bal. (endemic to Turkey), P. lithospermifolium (Lam.) Grande subsp. cariense (Boiss.) R. Mill var. cariense, P. kurdistanicum (Brand) R. Mill (endemic to Turkey), P. sintenisii Hausskn. ex Bornm., and P. strictum (C. Koch) Boiss.
