The genus Anisotes (Acanthaceae), a taxonomic revision

The genus Anisotes Nees is revised. A total of 24 taxa had previously been described. In the present revision 19 species, 3 subspecies and 1 variety are recognized. A new infrageneric classification of Anisotes is proposed.
In the general part the morphology, with special emphasis on pollen morphology, and the diagnostic characters of the genus are outlined. Phytogeographical and ecological aspects are discussed in relation to the phytogeographical division of Africa.     

On the validity of the genera Sinocalamus McClure and Lingnania McClure

When F. A. McClure published the new genus Sinocalamus McClure in 1940, the 4 species he listed are S. latiflorus (Munro) McClure, S. beecheyanus (Munro) McClure, S. oldhami (Munro) McClure and S. affinis (Rendle) McClure. After careful examination, the authors of this paper considered that the type species of McClure’s genus S. latiflorus (Munro) McClure should belong to the genus Dendrocalamus Nees, and the other species are of Bambusa Schreber. Owing to Sinocalamus McClure is not a taxon representative of its type species, but a mixture, it must be rejected as a synonym of Dendrocalamus Nees. In consequence then, the authors make adjustment to the taxonomic category of the 14 species and 1 variety which have ever been in Sinocalamus McClure. As for the characters of Lingnania McClure, except that some differences exist in the vegetative parts, the structure of the spikelets is in the main the same as that of Bambusa Schreber. Consequently, with regard to the systematic relationship, the authors consider it may be more resonable that the rank of Lingnania McClure should be altered to Bambusa Schreber subg. Lingnania (MeClure) Chia et H. L. Fung; all the species of Lingnania McClure, except that L. tsiangii McClure should be transferred to Dendrocalamus Nees, should be assignable to Bambusa Schreber subg. Lingnania (McClure) Chia et H. L. Fung.

木姜子属及山胡椒属的平行演化

本文阐述樟科木姜子属及山胡椒属两者在形态、分布、起源及演化等方面有许多共同之处,不仅在属内具有平行演化的情况,而且各自平行演化成单花木姜子属Dodecade-nia和单花山胡椒属Iteadaphne。同时两者又分别自4药室的拟檫木属Parasassafras和2药室的黄脉檫木属Sinosassafras演化而来。本文将单花木姜子亚属Litsea subg.UniflosYang et P.H.Huang归入单花木姜子属,并把Litsea monantha Yang et P.H.Hu-ang一种作为单花木姜子(原变种)Dodecadenia grandiflora Nees var.grandiflora的新异名,恢复了单花山胡椒属Iteadaphne B1.,并将香面叶Lindera caudata(Nees)Hook.f.重新组合归入该属为I.caudata(Nees)H.W.Li,comb.nov。此外,本文还发表了一个新属即黄脉檫木属Sinosassafras H.W.Li,gen.nov.,它具有2药室花药而不同于其平行演化的拟檫木属。

Cronisia and its two species,C. fimbriata and C. weddellii

The systematic position of Riccia fimbriata Nees, a species formerly known only in sterile condition and tentatively placed in the genus Exormotheca, is reexamined in the light of the recently discovered reproductive structures. The species proved to be a member of the genus Cronisia, identical to Cronisia mexicana Hicks, described in 1993. A key is provided to the two known species of Cronisia, C. fimbriata and C. weddellii, and they are described and illustrated.     

CYTOGENETIC STUDIES IN THE GENUS TRIBOLIUM (POACEAE: ARUNDINEAE)

The genus Tribolium Desv. consists of nine species, i.e., T. utriculosum (Nees) Renv., T. ciliare (Stapf) Renv., T. echinatum (Thunb.) Desv., T. hispidum (Thunb.) Desv., T. acutiflorum (Nees) Renv., T. obliterum sensu Davidse, T. glomeratum sensu Davidse, T. uniolae (L.f.) Renv., and T. brachystachyum (Nees) Renv. The genus has a basic chromosome number of 6, and from diploid to hexaploid specimens have been examined. Precocious segregation of metaphase I bivalents were observed in four species. Multivalent formation results in unequal chromosome segregation during anaphase I, and several cells with an 11–13 chromosome distribution have been observed. The presence of univalents and anaphase I bridges in all T. brachystachyum specimens suggests a hybrid origin for the species. B-chromosomes were present in specimens from four species. The B-chromosomes are similar to the euchromosomes with the exception that they do not participate in meiosis. The B-chromosomes have a possible isochromosome origin. The cytogenetic evidence presented supports the combination of Plagiochloa and Lasiochloa into Tribolium and indicates that the genus is closely related to Urochlaena, whereas it is not closely related to Prionanthium.     

Genomic relationships among diploid and hexaploid species of Andropogon (Poaceae).

Andropogon is a pantropical grass genus comprising 100-120 species and found mainly in the grasslands of Africa and the Americas. While the genomic relationships between many Andropogon species have been resolved by studying chromosome behavior in interspecific hybrids, relationships between the North and South American diploids have remained elusive. Further, the genome composition of two hexaploid species (including the important forage grass Andropogon lateralis Nees) has been unclear because of the strong hybridization barriers that exist between species. Consequently, genomic in situ hybridization was applied to shed light on these issues. The results confirmed that (i) both the South American (Andropogon selloanus (Hack.) Hack., Andropogon macrothrix Trin.) and North American (Andropogon gyrans Michx.) diploid species shared a common S genome and (ii) the S genome comprises just one of the three genomes in the hexaploids A. lateralis Nees and Andropogon bicornis L. The evolutionary and taxonomic implications of these findings are discussed.     

The taxonomy and biology of Stenosiphonium Nees (Acanthaceae)

A taxonomic revision of Stenosiphonium Nees is provided. Morphological variation within the genus is documented, the relationship between Stenosiphonium and Strobilanthes Blume is discussed, and problems of species delimitation are resolved. Three species are recognized. Stenosiphonium cordifolium (Vahl) Alston is morphologically variable and is widespread throughout peninsular India and Sri Lanka. S. setosum T. Anderson and S. wightii Bremek. are restricted endemics from the southern Western Ghats, each known from very few herbarium collections. Both S. setosum and S.wightii are recognized as rare in accordance with IUCN criteria. There is evidence to suggest that all three species of Stenosiphonium are plietesial which may explain the paucity of herbarium collections of both S. setosum and S. wightii. The implications of a plietesial lie history strategy for the assessment of the conservation status of these species is considered.
