| Abstract: | So far, the 15 genera of bamboos with creeping rhizomes in China have been known.
Based on the types and evolution of inflorescence, which have been discussed in the
paper, and other criteria of classification, the opinions are given as follows:
1. Some species of Semiarundinaria spp. McClure and Sinobambusa spp. McClure
should be separated and regarded as representing a new genus, because the racemes
of the some species are different from false inflorescence (indeterminate infl.) of the
type species of the two genera, and some other species should be transfered to the genus
Pleioblastus.
2. On account of the similarities in the type of inflorescence and pistil, Brachystachyum may be combined with Semiarundinaria.
3. As the inflorescence, pistil and rhizome of Sinarundinaria are similar in those
of Fargesia, the two genera should be combined. Due to the inflorescence of Fargesia
is different from that of Thamnocalamus, therefore, these two genera must be kept
separating.
4. Key to the Genera of Chinese bamboos with creeping rhizomes is provided inthis paper. But the key is available to flowering materials only, because the construction of it is mainly based on reproductive organs. |
