Gleason: Studies on West Indian Vernonieae 325 



Type, Britton & Wilson 5478, from a hillside, altitude 500 m., 

 in the Trinidad Mountains, Province of Santa Clara, Cuba, March 

 12, 1910, deposited in the Herbarium of the New York Botanical 

 Garden. 



The bracteal leaves have all fallen off the type specimen, except 

 a few fragments, and the leaves are crowded on short lateral 

 branches. The inflorescence is thus left at the end of a naked 

 peduncle 2-3 dm. long, giving the specimen an aspect entirely 

 unlike other species of the group. It is scarcely to be expected 

 that the same peculiarity will be maintained in other collections 



of the species. 



Vernonia aceratoides sp. nov. 



Vernonia inaeguiserrata angustijolia Griseb. Cat. PI. Cuba 144. 



1866. 



Slender and probably herbaceous; stem finely striate, closely 

 gray-tomentulose ; leaves firm, spreading or ascending, narrowly 

 oblong-lanceolate or lance-linear, the principal ones 7-8 crm long 

 and 1-1.2 cm. wide, acute and mucronulate at the tip, entire or 

 somewhat repand; obtuse or rounded at the base, minutely 

 scabrellate above and puberulent along the midvein, finely brown- 

 tomentulose beneath; veins prominent beneath and conspicu- 

 ously reticulated; petioles 2-3 mm. long; inflorescence terminal, 

 of about 3 short divaricately spreading cymes, bearing each six 

 or seven secund heads; bracteal leaves oblong, the upper ones not 

 exceeding the heads, and all proportionately broader than the 

 cauline; involucre narrowly campanulate, 5-6 mm. high; scales 

 closely and regularly imbricated, appressed, the outer ovate- 

 triangular, cuspidate, the inner with an ovate exposed portion, 

 rounded and apiculate at the tip. 



Grisebach's variety was based on a specimen of Wright 2784; 

 the preceding more detailed description is based on a sheet of the 

 same number in the Herbarium of the Missouri Botanical Garden. 



Species-group Longifoliae 

 The herbarium of Dr. Otto Kuntze contained a good specimen 

 of a Vernonia from St. Thomas, collected by Kuntze himself in 

 1874. and labeled Vernonia Thomae Benth. It can not be dis- 

 tinguished, however, in any essential character from Vernonia 

 albicaulis Pers., and the two species may henceforth be considered 

 identical. This disposition of V. Thomae was suggested before 

 by Gleason (Revision, 191), although at that time the two were
