Abstract
|
|
|
It wa found that Thalictrum thunbergii DC. var. hypoleucum has two distinct types, (Ⅰ) and (Ⅱ), with respect to the external morphology of the leaves, the number of stems attached to the root, and chromosome number.
Contrary to the previously reported chromosome number of 2n=42, the author found that the chromosome number of type Ⅰ is 2n=77, and that of type Ⅱ is 2n=84.
The anatomical examinations also revealed that type Ⅰ has dense root hairs and stone cells in the root cortex, and that type Ⅱ has sparse root hairs and no stone cells.
These different characteristics suggest that Tkalictrum thundergii DC. var. hypoleucum consist of two distinct taxa.
