Howe: Lichens from Jamaica 
263 
morpha Mull. Arg. Nos. 7, 8 and ia are referable to U . Vriese- 
ana Mont. & Bosch., 3 and are all Pachynae, as is Mr. Merrill’s 
Lich. Exc. No. 109. No. id seems referable to U. denudata Smith 
(Rees, Enel. Arts. Sci Lit. 37: 1817), a naked, subpendulous 
plant of the Mesinae described from Otaheite. Nos. 2 and 6 
(in part), as is Mr. Merrill’s distribution Lich. Exc. No. 159, are 
dicroic 4 conditions of U. ceratina. One example of No. 6 is a 
typical U. angulata Ach. Dr. Riddle has kindly given me the fol- 
lowing notes on U. jamaicensis Ach., made by him of the type 
preserved at Helsingfors. Though not as yet discovered in ma- 
terial examined from Jamaica it seems a fitting place to give its 
diagnostic characters. “ It is a short rather stout plant, appar- 
ently erect, 4 cm. long and 1-13 mm. thick, — scabrous with copi- 
ous, very minute papillae — much branched, but with very few 
fibrils — apothecia frequent, 1.5-3 mm. lat.” Dr. Elfvring has also 
kindly sent me a fibril section which shows it to be a Mesinae. 
Dr. Wainio considered it synonymous with U. aspera (Eschw.) 
Wain. 
The material collected by Dr. Cushman, not discussed above, 
seems to represent the following species. It was collected in 
March, 1912, at Catadupa (1,200 ft.), Montego Bay (up to 500 
ft.), Mandeville (2,000 ft.), and Newcastle (4,000 ft.). In part 
it represents U. concinna Strt., and U. radiata Strt., both Pa- 
chynae; in part U. [Eumitria] implicita Strt. as mentioned above. 
The pendulous species are U. angulata Ach., not entirely typical, 
and a terete, robust species suggesting U. longissima Ach., but 
having a curious brown axis, and probably U. mekista Strt. One 
example of this material having the brown axis I am unable to 
name, and yet entirely unwilling, under the circumstances, to de- 
scribe as new.

3 Since this paper was written, Dr. Yongman of Leiden has sent me for 
examination a part of the type of U. Vrieseana. It proves to be, instead of a 
Pachynae, as designated by Dr. Zahlbruckner, a Leptinae, and very closely 
allied, if not identical, with U. articulata (L.) Hoffm. These specimens are 
therefore probably to be referred to JJ. gracilis Ach.
