Blake — New and Noteworthy Compositae 49 
Herb.). — Very distinct from any other species of this genus in 
its dense glandularity, which gives to the dried plant a somewhat 
yellowish hue. 
Srerractinia Klattii (Rob. & Greenm.), comb. nov. — Pery- 
menium Klattii Rob. & Greenm.! Proc. Am. Acad. xxxiv. 528 
(1899). — The neutral rays of this species necessitate its transfer 
to Steiractinia. It is nearest S. oyedaeoides Blake, Journ. Bot. 
lili. 156 (1915), but differs among other features in its lance-ovate 
leaves long-cuneate at base. Lehmann 3282, the type, now in the 
Gray Herbarium, was originally recorded by Klatt (Bot. Jahrb, 
viii. 43) as Perymenium grande Hemsl., and it is of interest in this 
connection that fragments of a young Perymenium almost certainly 
of that species are mounted on the same sheet with the large speci- 
men from which P. Klattii was described. It is perhaps doubtful, 
however, whether they were really collected by Lehmann under 
his number 3282, for P. grande Hemsl. is not as yet definitely 
known from Colombia.
