Systematics of Disakisperma (Poaceae, Chloridoideae, Chlorideae)
Disakisperma Steud. is a genus of four predominantly perennial C4 (NAD-ME) species in the Americas, Africa, and Asia. Its species previously were treated in Eleusine, Eragrostis, Coelachyrum, Cypholepis, Leptochloa, or Diplachne by nearly all authors.It includes the widespread North and South American amphitropical disjunct Disakisperma dubium (type of the genus), Disakisperma eleusine from sou...
متن کاملSystematics of Trigonochloa (Poaceae, Chloridoideae, Chlorideae)
A systematic treatment including descriptions and a key for identification is provided for the two species of Trigonochloa, a genus recently segregated from the polyphyletic Leptochloa s.l. Trigonochloa ranges from southern Africa east to India and Sri Lanka, reflecting the widely ranging Trigonochloa uniflora. Trigonochloa rupestris has a more limited distribution from East Africa to Yemen. Tr...
متن کاملMonograph of Diplachne (Poaceae, Chloridoideae, Cynodonteae)
Diplachne P. Beauv. comprises two species with C4 (NAD-ME) photosynthesis. Diplachne fusca has a nearly pantropical-pantemperate distribution with four subspecies: D. fusca subsp. fusca is Paleotropical with native distributions in Africa, southern Asia and Australia; the widespread Australian endemic D. f. subsp. muelleri; and D. f. subsp. fascicularis and D. f. subsp. uninervia occurring in t...
متن کاملSystematics of California Grasses (Poaceae)
The grass family (Poaceae or Gramineae) is the fourth largest flowering plant family in the world and contains about 11,000 species in 800 genera worldwide. Twenty-three genera contain 100 or more species or about half of all grass species, and almost half of the 800 genera are monotypic or diatypic, i.e., with only one or two species (Watson and Dallwitz 1992, 1999). Over the last 150 years th...
متن کاملLeaf Anatomy of Orcuttieae (poaceae: Chloridoideae): More Evidence of C4 Photosynthesis without Kranz Anatomy
C4 photosynthesis without Kranz anatomy (single-cell C4 photosynthesis) occurs in only 0.003% of known species of C4 flowering plants. To add insight into the evolution of C4 photosynthesis, we studied the tribe Orcuttieae (Poaceae: Chloridoideae), which has species that can grow under both aquatic and terrestrial conditions, and utilize single-cell C4 photosynthesis when growing submerged. Car...
