Phyllus is probably not distinct. A survey of Watson, Gray Syn. H., Tovey + Gray, seem to show that H. hirsutus and H. divaricatus are close together. The descriptions are poor in contrasting these two species if they actually are distinct species. Eupatorium sessilifolium, collected at Bull Run, Tenn, is the typical material, apparently a # one of its southern outposts. Nov. 13 (Wednesday). The Tullehoma area seems to be a center for Siephium. S. brachiatum Guthrie - known only from Cowan - is apparently confined to this area. It is a close relative of S. perfoliatum. The commonest species, to judge from herbarium specimens, is S. trifoliatum and to this species I believe that the opposite-leaved plant collected by me in 1930 at Grand Jct., belongs, and not to the hairy S. intrepidulum of the Great Plains. S. Mohrie was correctly named by me from Tullehoma, judging from the illustration in Mohr, and the peculiar pubescence seems rocky areas characteristic. Material from Bull Run, resembling S. scaberrimum is certainly S. Gatesii, and the material from damp shady places at Bull Run is characteristic S. trifoliatum, such as is seen from the Potomac region. Apparently a new variety of Zizia aurea from damp banks at Bull Run, differing from typical material in having pubescent lower surfaces of the leaves. Dissected and material of woodsia scopulina for Miss Curdy. The indusium is not like that of W. mexicana, but the outline of the pinnae appears decidedly different.
