46 The Botanical Gazette. [February, 
Willughaeya globosa, n. sp.—A glabrous twiner or some- 
what puberulent in the inflorescence: leaves ovate and acum- 
inate, obtuse at base, with margins (which are obscurely muc- 
ronulate) revolute, 5-ribbed near the base and prominently 
cross-veined, long-petioled, blade 9 to 12™ long, 5 to 7” 
broad: heads sessile in glomerate (head-like) clusters which 
are borne (one to seven in number, usually three or five) at 
the ends of the opposite somewhat wide-spreading branches 
of an elongated bracteate raceme: involucral scales very short 
(about one-third as long as the corolla and pappus), broad and 
truncate (sometimes alittle notched), glandular-puberulent at 
apex: pappus white: corolla narrowly funnel form: achenes 
glabrous (or very sparsely pubescent under a lens). “Santa 
Rosa, Depart. Santa Rosa, alt. 4,000°, March 1892, Heyde & 
Lux 3,430. : 
This species is listed as Mikania globosa Coulter, n. sp. if 
the forthcoming part of John Donnell Smith’s ‘‘Enumeratio 
Plantarum Guatemalensium,” where it seemed desirable to 
make the nomenclature consistent with that of the other 
parts. The inflorescence is striking, with its display of 
globose heads, and the species resembles closely in habit and 
structure Mikania smilacina DC. of Brazil. 
WILLUGBAEYA SCANDENS (L.) Kuntze. (Mikania scandens 
Willd.)—Santa Rosa, Depart. Santa Rosa, alt. 3-4,000; 
June 1892, Heyde & Lux 3,434. A form with purple flowers 
and reddish pappus, which is easily separated from the 
typical form, but which is referred by Hemsley to M. 
scandens. | 
Coleosanthus Pacayensis. (Brickellia Pacayensis Coulter).

ASTER SPINOSUS Benth.—Santa Rosa, Depart. Santa Rosa, 
alt. 3-4,000%, April and December 1892, Heyde & Lux 3,424 
and 4,210. The development of the characteristic spiny 
branches in these Guatemalan forms is much stronger than 10 
the forms heretofore collected in Northern Mexico and ad- 
jacent United States; a development that appears also if 
specimens from Costa Rica. The spines are often very strong 
and thick set, flattened like sword blades, 2.5 to 5™ long, 
evidently doing leaf-work, while the leaves are reduced to 
the merest rudiments, very different from the ‘‘soft subulate 
spines” of the more northern forms. The longer spines fre-_ 
quently branch.
