摘要/Abstract

Abstract:

The bamboos of China have been studied by some botanists both at home and abroad,

who paid rather less attention to a thoroughly systematic study than to describing new species

or new genera. In the course of our study, we found, some taxinomical mistakes that have

thrown the classification of bamboos into a great confusion. A species, for example, placed in

a wrong genus, or a genus contained some taxonomically divergent species which in fact belong

to different genera.

This paper is a revision of the bamboo classification including some genera and species

which occur in China and have been mistreated taxonomically.

Based on comparative morphology, we first propose to unite Yushania Keng f. with Sina-

rundinaria Nakai. According to Keng f. (1957), a sympodial rhizome with diageotropical

growth and scattered culms is a main feature distinguishing Yushania from Sinarundinaria, a

treatment which was supported and cited subsequently by W. L. Li (1963) and F. A.

McClure (1957, 1973) in their studies. In fact,the rhizome of the genus Sinarundinaria has

never been critically studied in detail. Nakai (1935) described it as a monopodial type from

carelessness, while most botanists asserted it to be an amphipodial one. We have carefully exa-

mined numerous specimens of the type species of Sinarundinaria Nakai (i. e. S. nitida (Mitf.)

Nakai) collected from Sichuan, Shaanxi, Gansu provinces where it occurs naturally, and disco-

vered that its rhizome is a sympodial type with diageotropical growth, too, identical with that

of the superfluous Yushania Keng f. Thus, Yushania must be united with Sinarundinaria.

In E. Asia, alpine bamboos with sympodial rhizomes, scattered culms and short infloresce-

nces enclosed in spathes have been separately placed in such genera as Arundinaria Michaux

(Hackel, 1887; Gamble, 1893), Thamnocalamus Munro (Munro, 1868; E. G. Camus,

1913), Fargesia Franch. (Franchet, 1893; E. G. Camus 1913; Nakai, 1925; Keng and

Keng f. 1957, 1959) and Sinarundinaria Nakai (Keng and Keng f. 1957, 1959). After a

careful examination of the specimens from various regions we are sure that they belong to a

natural group with common characters of the genus Thamnocalamus Munro. Consequently Far-

gesia Franch. should be combined with Thamnocalamus Munro.

We also examined some of the type specimens and original descriptions of 9 species of

Semiarundinaria collected from S. China and described in 1940 by McClure. A conclusion

reached is that all these species are not true Semiarundinaria Makino ex Nakai; most of them

should be transferred to Arundinaria Michaux, the rest to Sinobambusa Makino ex Nakai, and

other genera.

We also agree with the view of some botanists that the genus Sasamorpha Nakai should

be combined with the genus Sasa Makino et Shibata.

In addition, we have emended and recircumscribed the concepts of some genera, such as

Indocalamus and Sinarundinaria which are confused by Nakai himself, and make them more

natural. We have also disclaimed 5 specific binomials, transferred 7 species, and described 7 new species which belong to 5 genera separately.
