本文首次报道了菰属Zizania L. 及其有关属，共7属，13种，3变种，1变型的花粉形
态。通过光学显微镜和扫描电镜，对其花粉的形状、外壁的层次及纹饰等进行了观察。经过研
究，笔者认为： 菰属应置于禾本科稻族内；菰属在稻族内的演化及菰属内的种间演化均存在
平行演化的现象；菰属在全世界有4种2亚种。这些结论大都吻合笔者对其它形态特征的研
究结果。 相似文献

A new subspecies, Primula obconica subsp. fujianensis, is described. The genus
Primula is widely distributed throughout China, but it has never been previously recorded in Fujian
and Jiangsu. Recently the authors collected a specimen of the genus from Fujian for the first time. It
is obviously closely related to P. obconica, which is one of the most common species in China,
ranging from western Yunnan and Sichuan through Guizhou, Hubei to Hunan and northern Guang-
dong, with its most easterly extension in southern Jiangxi. Morphologically, the Fujian plant is char-
acterized by its much smaller stature and by the scapes being shorter than the leaf rosette, and in
many ways it is more closely related to P. obconica subsp. parva, but can be easily distinguished
by its smaller, white and homostylous flowers. As it is isolated both in distribution and reproductionwith other subspecies of P. obconica, here it is described as a new subspecies. 相似文献

In addition to describing a new species, Cypripedium wumengense, as well
as a new variety, C. bardolphianum var. zhongdianense, nomenclatural and taxonomic
notes are made on its allies and the division to which they belong. They are ltrge]y
found in the Hengduan Mountains in southwestern China, characterized by the absence
of bract, havirg lip more or less covered with small wart-like outgrowths, and that as
the capsule matures the scape becomes much elongated. Six species of this group have
hitherto been reported, of which, however, C. ebracteatum and C. nutans are regarded
here as conspecific with C. fargesii and C. bardolphianum respectively. Thus, including
the new taxa described here, it composes five species and one variety: C. bardolphianum
W. W. Sm. et Farrer (var. bardolphianum and var. zhongdianense S. C. Chen), C. mic-
ranthum Franch., C. fargesii Franch., C. margaritaceum Franch. and C. wumengense
S. C. Chen. They are all grouped here into the same section, Sect. Trigonopedium
(Franch.) Pfitz., the oldest legitimate name of this group in the rank of section. 相似文献
