Further notes on Bolivian <Emphasis Type="Italic">Justicia</Emphasis> L. (Acanthaceae)

Two new taxa of Justicia are recognised from Bolivia. Justicia fuentesii J. R. I. Wood is described as a new species. The two isolated populations of Justicia mesetarum Wassh. & J. R. I. Wood can be distinguished by a range of minor morphological differences and are treated as distinct subspecies with subsp. chiquitana J. R. I. Wood described as new. The new taxa are illustrated and mapped.     

New names,combinations and synonyms in <Emphasis Type="Italic">Justicia</Emphasis> and <Emphasis Type="Italic">Stenostephanus</Emphasis> (Acanthaceae)

Summary  Preparation of a catalogue of the plants of Colombia requires 30 new combinations in Stenostephanus Nees and five in Justicia L. to bring nomenclature up to date. Three new names Justicia littoralis J. R. I. Wood, J. albicans J. R. I. Wood and J. magdalenensis J. R. I. Wood are coined for Jacobinia lindaviana Rusby, Chaetothylax leucantha Leonard and Justicia disparifolia J. R. I. Wood respectively. The genus Pelecostemon Leonard is considered to belong to sect. Chaetothylax (Nees) V. A. W. Graham of Justicia L. Several species of Stenostephanus from Colombia and Venezuela are treated as synonyms of earlier species.     

<Emphasis Type="Italic">Plantago pyrophila</Emphasis> (Plantaginaceae), a new species from the cerrados of Eastern Bolivia

A new species Plantago pyrophila Villarroel & J. R. I. Wood is described from the Serranias de Santiago de Chiquitos in the cerrados of eastern Bolivia. It is clearly adapted to survival in the cerrado environment where grassland fires are a frequent event. The new species is remarkable for being geographically isolated from other species of the genus, being the only species of Plantago known from the cerrado biome.     

A revision of Tecoma Juss. (Bignoniaceae) in Bolivia

A revision of the genus Tecoma in Bolivia based on the author's herbarium research and extensive field observations is presented. Species delimitation is re-evaluated, resulting in the recognition of only four species, one of which, T. beckii J. R. I. Wood, is described as new. Tecoma sambucifolia is treated as var. sambucifolia (Kunth) J. R. I. Wood of the widespread and variable T. stans (L.) Juss., as it can only be distinguished on the basis of minor morphological characters and is not as geographically restricted as has been supposed. Tecoma fulva (Cav.) D. Don is treated as a variable species extending from central Peru to Chile and northern Argentina with six subspecies: ssp. fulva , ssp. guarume (A. DC.) J. R. I. Wood, ssp. tanaeciiflora (Kränzlin) J. R. I. Wood, ssp. arequipensis (Sprague) J. R. I. Wood, ssp. garrocha (Hieron.) J. R. I. Wood, and ssp. altoandina J. R. I. Wood, the latter described as new. The differences between T. tenuiflora (A. DC.) Fabris and the Peruvian T. rosifolia Kunth are discussed. Hybrids are formally recognized in the genus for the first time, and the implications for the accepted corolla morphology and pollination syndromes are discussed. Maps illustrate the geographical distributions of the species. All taxa discussed in the paper are illustrated.  © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society , 2008, 156 , 143–172.     

New and reassessed species of Strobilanthes (Acanthaceae) in the flora of China

Several problems in Strobilanthes Blume (Acanthaceae: Ruelliae) are clarified as a result of collaboration between Chinese and western botanists. Examination of pollen has permitted clear delimitation of four morphologically similar species, Strobilanthes szechuanica (Batalin) J. R. I. Wood & Y. F. Deng, S. labordei H. Lév., S. wakasana Wakasugi & Naruhashi and S. wilsonii J. R. I. Wood & Y. F. Deng, the latter described for the first time in this paper, although first collected more than a hundred years ago. A key is provided to help distinguish these species. The globose, echinulate pollen found in several species from China and Japan and assigned to the genus Championella by Bremekamp is shown by SEM photography to be distinct from other pollen hitherto regarded as the same. Three new species, S. abbreviata Y. F. Deng & J. R. I. Wood, S. lihengiae Y. F. Deng & J. R. I. Wood and S. vallicola Y. F. Deng & J. R. I. Wood are described. S. austinii C. B. Clarke ex W. W. Sm. is lectotypified to show that it is conspecific with S. lamiifolia (Nees) T. Anderson, a species demonstrating trans-Himalayan links. New combinations are made for four species as the authors recognize only a single genus, Strobilanthes within the Strobilanthinae as defined by Bremekamp. S. gongshanensis Tsui and S. aenobarba W. W. Sm. are shown to be only varieties of S. inflata T. Anderson. Illustrations are provided for all new species.  © 2006 The Linnean Society of London, Botanical Journal of the Linnean Society , 2006, 150 , 369–390.

Centaurea rahiminejadii sp. nov. and a new record in the genus Centaurea (Asteraceae,Cardueae–Centaureinae) from Iran

A new species, Centaurea rahiminejadii Negaresh (Asteraceae) in C. sect. Cynaroides Boiss. ex Walp., is described and illustrated from the Kermanshah Province, west Iran. It is morphologically similar to Centaurea regia Boiss. subsp. regia. Diagnostic morphological of this and closely related taxa are discussed and presented. The ecology, habitat and conservation status of the new species are also described. In addition, Centaurea regia subsp. cynarocephala (Wagenitz) Wagenitz is reported as a new record to the flora of Iran. Finally, the geographic distribution of the new species and closely related species is presented and mapped.     

Rhododendron aureodorsale (Ericaceae) comb. nov. from southwestern Shaanxi,China

In this paper, we propose that Rhododendron clementinae Forrest ex W. W. Sm. subsp. aureodorsale W. P. Fang ex J. Q. Fu should be recognized at species rank as Rhododendron aureodorsale (W. P. Fang ex J. Q. Fu) Y. P. Ma & J. Nielsen. This species is similar to R. clementinae, but has an isolated distribution range, and differs by having tawny indumentum without pellicle on the abaxial leaf surface, sparse hairs on both pedicel and sepals, and always 7 corolla lobes.     

<Emphasis Type="Italic">Mastigostyla</Emphasis> I. M. Johnst. in Bolivia: three new species and new data on <Emphasis Type="Italic">M. cardenasii</Emphasis> R. C. Foster

Four species of Mastigostyla (Iridaceae) from Bolivia are described, illustrated and maps of their distribution provided: M. cardenasii R. C. Foster, M. chuquisacensis Huaylla & Wilkin, M. torotoroensis Huaylla & Wilkin and M. woodii Huaylla & Wilkin, the last three as new species. Mastigostyla gracilis R. C. Foster is synonymised under M. cardenasii R. C. Foster. Notes on conservation status, nomenclature and identification are included. Although some uncertainty exists over generic placement due to phylogenetic systematic research now in progress, marked infraspecific variation is documented for the first time within South American Tigridieae. This draws attention to the need for more extensive sampling if adequate species delimitation is to be achieved in Tigridieae. Photographs illustrate morphological variation in all four species. A key is provided to facilitate identification of Bolivian Mastigostyla.     

Centaurea cadmea subsp. pontica subsp. nov. (Asteraceae) from northwest Anatolia,Turkey

Centaurea cadmea Boiss. subsp. pontica Wagenitz ex Y.B. Köse & Ocak (Asteraceae), a new subspecies occuring in north Anatolia, Turkey, is described and illustrated. The new subspecies grows in rocky places in the Zonguldak province. It is closely related to C. cadmea subsp. cadmea, but differs in its involucrum, achen, appendage and radiant flowers. Diagnostic morphological characters are discussed and notes are presented on ecology and conservation status. In addition, the pollen characteristics of both subspecies have been examined by SEM.     

Jurinea cataonica subsp. mardinensis subsp. nov. (Asteraceae) from southeast Anatolia,Turkey

A new subspecies, Jurinea cataonica Boiss. & Hausskn. subsp. mardinensis B. Do?an & A. Duran (Asteraceae), is described and illustrated from Anatolia, Turkey. The subspecies grows on abandoned fields in the Bakirkiri place (C8 Mardin Province) in southeastern Anatolia. It is morphologically similar to J. cataonica subsp. cataonica. Diagnostic morphological characters between these closely similar taxa are discussed and arranged in a key. Ecology and conservation status of the subspecies is also presented. In addition, the geographical distributions of the new subspecies and other related species are given.
