Stachys beckeana (Labiatae) in Albanien und Jugoslawien

Morphological and cytological investigations were carried out inStachys beckeana Dörfler & Hayek andS. recta L. subsp.sarajevensis sensuHayek. These two taxa have the same morphological characteristics (shape and indumentum of leaves; morphology of sepals, petals and fruits) and both have 2n = 2x = 34 chromosomes. They cannot be considered as different taxa;S. beckeana Dörfler & Hayek is the valid name (synonyms:S. recta L. subsp.sarajevensis sensuHayek,S. hayekii Malý,S. recta L. subsp.hayekii Malý).

A New Species ofSalvia (Lamiaceae) from the Sierra de Los Tuxtlas,Mexico

Salvia tuxtlensis, sp. n., is immediately recognized by its semipersistent bracts and yellow flowers. Its affinities are not clear. It is endemic to the Soteapan area in the Sierra de Los Tuxtlas, in Veracruz, Mexico.     

Micromorphological and phytochemical characters ofTeucrium marum andT. subspinosum (Labiatae) from Sardinia and Balearic Islands

Micromorphology and distribution of trichomes in different plant parts ofTeucrium marum andTeucrium subspinosum from Sardinia and the Balearic Islands are described. The composition of volatile compounds in the same plants has also been studied. The occurrence in Sardinia of two differentT. marum entities is evidenced. One of them, growing in the NW. part of the island, is very similar toT. marum from Minorca.T. subspinosum from Sardinia and Majorca differ for the presence in the last one of short capitate hairs and for a higher ratio of dolichodial/teucrein. While the degree of variability of all the characters is very high, there is a good homogeneity between all the taxa, due to the presence of monoterpene cyclopentanoids not found until now in other species.

Six new species ofGagea (Liliaceae) from the Flora Iranica area

Six new species are described:Gagea anonyma, G. Staintonii, G. siphonantha, G. Grey-Wilsonii, G. chloroneura. All belong to subgen.Platyspermum (Boiss.)Miscz. Florae Iranicae praecursores63–68. — Praecursores praecurrentes: Pl. Syst. Evol.151, 281–293 (1986).     

The genusCarex (Cyperaceae) in the Flora Iranica area

88 species and 20 subspecies ofCarex, altogether 94 taxa, occur in the area ofRechinger's Flora Iranica. Of these, 48 taxa, have an Euro-Siberian, 11 an Irano-Turanian and 35 a Central Asiatic distribution, the last including five species with connections to E. and tropical SE. Asia. The Saharo-Sindian element is missing. Endemic taxa are found in all groups. Eight taxa, endemic to the NW. Himalayas occur in the E. part of the area. The Euro-Siberian taxa are concentrated in the NW. of the area, but have connections to the east; similarly, Central-Asiatic taxa are concentrated in E. Afghanistan and N. Pakistan, but have connections to the west. Some Euro-Siberian taxa are widely distributed in the area, but avoid the most arid regions. The Irano-Turanian taxa are few and extend from Egypt through the area of Flora Iranica to Kazakhstan SSR and Central China.Dedicated to Hofrat Univ.-Prof. DrK. H. Rechinger on the occasion of his 80th birthday.     

On the distribution of the genusCousinia (Compositae)

On the basis of new floristic works a distribution map of the genusCousinia is given and discussed. The generic distribution area ofCousinia is nearly identical with the Irano-Turanian Region, but most of the 662 species are concentrated on the Iranian and Turkestanian mountain regions. Here, both in the eastern and in the western parts of the distribution area, four centres of diversity with high numbers of—mostly endemic—species are found: The western Tienshan (61 species), Pamiro-Alaj (169), NE-Afghanistan (80), NW-Afghanistan (44); Kopetdagh (66 in Iran, 33 in Turkmenia), Elburz (66), the northern part of Zagros (44), Azerbaijan (36). The outlines of the generic area are formed by genetic-historical and by climatic factors. The distribution patterns ofCousinia species confirm the close connections between the Iranian and the Turkestanian mountains as centres of origin and conservation of palaeo-xeromorphic mountain floras, contrasting with the Turanian lowland flora.Dedicated to Prof.K. H. Rechinger on the occasion of his 80th birthday.     

Labiatae Novae Iranicae

Four new species are described:Lavandula sublepidota, from S. Iran (related toL. coronopifolia),Phlomis pachyphylla from S. Iran, Prov. Fars (nearPh. polioxantha),Satureia isophylla from N. Iran, Prov. Mazanderan (close toS. mutica andS. intermedia), andThymbra neurophylla from Iraqi Kurdistan (distinct forth species of the genus).

Pollination ofPlectranthus vestitus (Lamiaceae) by trap-lining hovering bees in Madagascar

In a primary forest on the Central Plateau of MadagascarPlectranthus vestitus (Lamiaceae) was principally pollinated by the beePachymelus limbatus (Hymenoptera, Anthophoridae). A species ofStylogaster (Diptera, Conopidae) acted as a co-pollinator. Flower — pollinator interactions are described. The bee performed pollination while hovering, a flower-visit lasting onlyc. 0.3 seconds. Floral features such as shape and size of the corolla tube, and the lack of a landing place suggest specialization to hovering anthophorid beepollinators. Floral biology and pollination in the genusPlectranthus are discussed.     

Taxonomy ofCarminatia (Asteraceae,Eupatorieae)

A taxonomic study of the largely Mexican genusCarminatia is rendered. It is comprised of three closely related species:C. tenuiflora, C. recondita andC. anomala spec. nova. Illustrations, dot maps, keys to species and complete synonymy are presented.     

Two new species ofConsolida (Ranunculaceae) from the Flora Iranica area

Notes on the capsule dehiscence inAcanthophyllum (Caryophyllaceae) and allied genera

The shape and the mode of dehiscence of the capsule had been regarded as good differential characters betweenAcanthophyllum and related genera.—Studies of these characters, including the shape of the ovary, in species ofAcanthophyllum, Diaphanoptera, Ochotonophila andScleranthopsis show, however, that they cannot be used as differential characters for the genusAcanthophyllum.

A taxonomical revision ofThymus sect.Teucrioides (Lamiaceae)

TheThymus teucrioides Boiss. & Spruner aggregate is revised and the following new taxa, all from the alpine zone in the Greek mountains, are described:Th. leucospermus Hartvig from the calcareous mountains of Pindhos and Mt Parnassos in Sterea Ellas,Th. rechingeri Hartvig with the subsp.macrocalyx Hartvig from calcareous mountains in Sterea Ellas and N Peloponnissos, andTh. teucrioides subsp.alpinus Hartvig from the serpentine areas of N Pindhos. In the variableTh. teucrioides s. str. many characters have turned out to be markedly geographically correlated and many local populations can be distinguished by a particular combination of characters.Dedicated to Prof.K. H. Rechinger on the occasion of his 80th birthday.     

Differentiation patterns in the E. MediterraneanScutellaria rubicunda group (Lamiaceae)

Strict sterility barriers where found between theScutellaria populations on Sicily and the Greek populations. The material from Samos is separated by a strict sterility barrier from the other Greek populations. In contrast, the populations on mainland Greece and adjacent islands are all ± interfertile. Three species are recognized,S. rubicunda Hornem., endemic to Sicily, andS. brevibracteata subsp.icarica, endemic to Samos and Ikaria. All other populations are referred toS. rupestris with eight subspecies, most of which are endemic to one island or to one mountain. Three new subspecies are described, viz. subsp.rechingeri and subsp.olympica, endemic to mt Vourinos and mt Olympus in North Greece, respectively, and subsp.caroli-henrici, native to the Malea peninsula of Peloponnisos. The phytogeographical connections and genetic differentiation within and between populations are discussed.Dedicated to Prof. DrK. H. Rechinger on the occasion of his 80th birthday.     

Evolution alpiner Populationen vonEuphrasia (Scrophulariaceae): Die tetraploideE. minima

A systematic analysis of the variable and probably allotetraploidE. minima is presented, its infraspecific taxonomy is discussed.E. tatrae is provisionally included intoE. minima although some differences may exist;E. mendonçae may be a relic of a formerly wider distribution ofE. minima; E. willkommii seems to be closer toE. stricta s. lat. than toE. minima. 4x-E. minima is supposed to be derived from phylogenetic lines close to extant dwarf alpine forms of 2x-E. alpina (including its yellow flowering subsp.christii;Vitek 1985b) and 2x-E. hirtella (vgl.Vitek 1985a). Some characteristics (e.g., its small flowers) could have been introduced through hybrid introgression from other 2x-species, particularlyE. inopinata and/orE. sinuata (vgl.Ehrendorfer & Vitek 1984).     

A newFerulago (Apiaceae) species from Turkey
