ROBINSON. — ON CERTAIN COMPOSITAE, 211 
now incorporated in the Gray Herbarium, there is a single head and an 
excellent sketch of Klatt’s type, both of which clearly show the species 
to have been an Jostephane, identical so far as can be seen with the 
earlier J. trilobata of Hemsley. Here also should be placed, as it ap- 
pears, the recently published Gymnolomia scaposa Brandegee, Univ. 
Calif. Publ. Bot. iv. 93 (1910). 
Perymenium Peckii, sp. nov., fruticosum gracile 3-9 m. altum in 
plantis adjacentibus se suffulciens quasi scandens; caule tetragono 
scabro in speciminibus siccatis 4-sulcato brunneo, internodiis 4—5 em. 
longis ; foliis oppositis lanceolatis tenuibus graciliter petiolatis acumi- 
natis obscure et remote serrulatis 3-nerviis basi rotundato-subacutis 
5 cm. longis 1.5 cm. latis supra viridibus minute et adpresse pilosis 
subtus distincte pallidioribus molliter pubescentibus fere tomentosis 
non solum in nerviis sed etiam inter eas; petiolo 7-9 mm. longo; 
panicula oppositiramea ovoidea foliaceo-bracteata 1.3 dm. longa 1 dm. 
diametro, ramis curvato-adscendentibus, corymbulis ca. 2 cm. diametro 
5-7-capitulatis, pedicellis gracilibus 2-8 mm. longis; capitulis ca. 5- 
radiatis 6 mm. altis ; involucri ovoidei squamis inaequalibus late ovatis 
obtusis strigillosis ; ligulis albidis apice profunde 2-3-dentatis vel etiam 
-lobatis ca. 4 mm. longis fertilibus ; flosculis disci ca. 15; achaeniis 
valde immaturis compressis oblanceolatis; pappi aristis ca. 10 valde 
inaequalibus stramineis scabridis. —In openings in the forest, British 
Honduras, Prof. Morton E. Peck, no. 284 (type, in Gray Herb.). This 
Species is most nearly related to P. microcephalum Sch. Bip., which, 
however, has longer bright yellow ligules nearly entire at the tip, and 
leaves of a very different pubescence, the lower surface being nearly 
smooth except along the strigillose nerves. 
Risen: Pee Robinson & Greenman, Proc. Am. Acad. 
xxxiv, 559 (1899). This species, hitherto known only from Venezuela, 
may be recorded from Colombia, where it was collected in Santa Marta, 
November, 1898-1901, altitude 460 m., by H. H. Smith, no. 510 (Gray 
Herb.). Mr. Smith’s specimen examined is immature (still in bud), 
but shows clear identity with the Venezuelan plant. It was pees 
uted as V. diversifolia DC., a species which has alternate leaves an 
many other differences. : y
