Some populations in Texas and Mexico have red-margined leaves but seem to be uncorrelated geographically.
德州和墨西哥的一些种群有红边,但红边这一特征似乎与地理分布无关。
A plant collected by A. Lau in the Sierra Gomas, west of Bustamante, Nuevo León, has unusually broad leaves (to 4 cm wide) and after further study may be proposed as a new variety or species.
A. Lau曾在Nuevo León州Bustamante西部的Gomas山脉收集到一棵植株,它有着不同寻常的宽叶子(宽达4cm),更进一步的研究可能会提出这是一个新的变种乃至物种。
