1893.] Undescribed plants from Guatemala. 203 
narrow elongated inflorescence and oblong fruits with very 
numerous grains. The leaves of XA. Po/ophyllus resemble 
those of R. floribundus H. B. K., which has, however, a dense 
panicle, short pedicels and no glandular bristles. The knowl- 
edge of all these species is imperfect, and they require a more 
careful examination in their natural stations, As far as we 
can judge from the dried branches, it would be quite un- 
natural to put them under the same specific name. The spe- 
cimens of this plant are nearly allalike; in no. 2,535 the pedi- 
cels bear besides the scattered long glandular bristles a quan- 
tity of short-pedicelled glands. In the Berlin Herbarium I 
have seen a specimen of this plant from Mexico (Otlamaltatle, 
Depart. Zacualtip, Prov. Hidalgo; leg. Seler sub no. 879).

Mallostoma Shannoni.—Cespitose: stems prostrate, root-

bristles replaced by glandular teeth, short flat petioles decur- 
rent in a pubescent wing, leaves oval to elliptical-oblong 
(23-4X 1-2"), conterminously obtuse oracute, coriaceous, vena- 
tion obscure, like stems rubro-punctate, revolute margin and 
midrib beneath pubescent: flowers terminal, solitary, 4-mer- 
ous, S'long: calyx-lobes triangular-lanceolate (1), equalling 
turbinate tube and ebracteate peduncle, truncate sinuses 
glandular-denticulate: lobes of infundibuliform corolla some- 
. what shorter than tube, ovate-oblong, scaly-pubescent within, 
throat naked: filaments short (3): style a third shorter than .
