Re: H clausa

Ben is correct about H. clausa var. clausa. It is completely pollen/pod
sterile. M. G. Chung and myself have observed populations in Korea that
never produce flowers and propagate by rhizomatous extensions. This form is
described in my book, p. 43. The name H. clausa var. (or f.) stolonifera has
been mentioned but is a nomen nudum. It would be technically incorrect
because the method of propagation is not by aboveground stolons but by
underground rhizome extensions. BTW, Chung mentions that he has never
observed H. clausa var. clausa in the wild and neither have I.
