TROPICAL AMERICAN COMPOSITAE. 41 
ScHIZOTRICHIA EUPATORIOIDES Benth. in Benth. & Hook. f. Gen. ii. 
410 (1873). A specimen of this rare and highly interesting generic 
monotype has been found among some Eupatoriums kindly lent to the 
writer from the New York Botanical Garden. Although unidentified, 
this specimen, collected in Peru by Mathews and corresponding in all 
described details with Bentham’s clear diagnosis, is with scarcely a 
doubt a part of the original material secured by Mathews at Chacha- 
poyas about 1836. Bentham in his treatment (I. c.) places the genus 
among the Helenieae, but adds at the end the remark that the plant 
might perhaps rather belong to Ewpatorium. However, its short, blunt, 
and strongly recurved style-branches, its involucral scales marked with 
the immersed elongated glands characteristic of certain Helenieae, the 
subterete achenes, and the peculiar pappus of fimbriate scales all are 
foreign to or very unusual in the Eupatorium tribe, with which it cer- 
tainly can have nothing to do. 
Although Bentham gives a somewhat detailed generic character and 
mentions a specific name, he gives no specific diagnosis. To place the 
plant upon a somewhat more regular footing in this regard the following 
brief character may be put on record: 
5. EUPATORIOIDES Benth., 1. ¢., lignescens paullo pubescens; ramis 
dichotomis subteretibus foliosis; foliis elliptico-ovatis crenulatis tenui- 
bus apice rotundatis et mucronatis basi rotundatis penniveniis 2-2.5 cm. 
longis 1-1.5 em. latis breviter petiolatis; cymis sessilibus laxis composi- 
us; bracteis minutis squamiformibus, pedicellis filiformibus glabris 
a ad 1.5 oe longis; capitulis ca. 8 mm. altis et crassis; involucri 
eae principibus ca. 8 elliptico-oblongis tenuibus glabris subaequali- 
us dorso cum glandulis flavidis elongatis munitis; flosculis ut a Benth- 
amio descriptis.— Perv: Chachapoyas, Mathews. In habit somewhat 
Suggesting Porophyllum.
