ROBINSOX. — 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 lostephane, identical so far as can be seen with the 

 earlier /. trilohata 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 cm. 

 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 pabescentibus 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. miavcephalum 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. 



Verbesina caracasana 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 distrib- 

 uted as F. dlversifolia DC, a species which has alternate leaves and 

 many other differences. 



Verbesina Columbiana, sp. nov., ubique griseo-puberula verisi- 

 militer herbacea alta robusta ; caule teretiusculo exalato striato-angu- 

 lato medulloso ; foliis alternis pinnatifidis 2-3 dm. longis 1.2-1.7 dm. 

 latis utrinque griseo-viridibus dense et scabriuscule puberulis, lobis 

 ca. 7, oblongis vel oblongo-lanceolatis acuminatis serrulatis 1-7 cm. 

 longis 0.7-2.5 cm. latis; petiolo 6-8 cm. longo bialato 1.5-1.7 cm. 

 latitudine basi biauriculato ; inflorescentia composite corymbosa plana
