Blake — New and Noteworthy Compositae 29 
Sr. VincENts: top of the Lonfrére (?) Volcano, 610-915 m., June, 
H. H. & W. G. Smith 1931. Venrzue.a: Tovar, 1980 m., 1854- 
55, Fendler 669. Braziu: N. W. Schroeder. — Not to be sharply 
separated from the typical form of the species. 
E. Bponarrensis L. forma Fitirotius Chod. ! Bull. Herb. Boiss. 
ser. 2, iii. 714 (1903), as filifolia.—A peculiar form, based on 
Hassler 7023 from Paraguay, in which the involucre is as in var. 
leiothecus but the leaves very numerous, linear (1.5 mm. wide or 
less) and sparsely hispid-ciliate, the stem sparsely hispid-pilose. 
A plant from Rio Negro, Northern Patagonia, collected by the 
Wilkes Expedition, and identical except for the undoubtedly 
purely individual feature that its lower leaves are slightly broader 
and bear 2-4 narrow lateral lobes, was labelled by Dr. Gray E. 
spiculosus H. & A. var. minor Hook. fil. (Fl. Antare. ii. 307 (1847). 
The plant is worthy of further study. EH. spiculosus H. & A. var. 
glabellus H. & A. Comp. Bot. Mag. ii. 49 (1836), nomen, is referred 
by J. D. Hooker I. c. to EZ. alpinus. 
ERIGERON GNAPHALIOIDES HBK. This species has become 
rather badly confused in herbaria not only with one or two near 
relatives, but also with the at least technically very distinct Conyza 
gnaphalioides HBK. The following citation of specimens and 
essential characters will it is hoped lead to a clearer understanding 
of this puzzling group.
