1893.] Undescribed plants from Guatemala. 201 
H. discolor, and narrow cuneate leaves tapering into the short 
stalk. After all it seems to be more natural to put it under 
H. argenteus than under A. discolor; but it may be doubted 
if true limits exist between these two pretended species. The 
specimen n. 3,034 is a very large one, and was gathered 
from a bush 3-4 yards high. Theplant represented in H. B. K. 
Nov. gen. Amer. VI. tab. 562, as well as Guatemala spec- 
imens in. the Berlin Herbarium, are very much smaller. (W. 
O. Focke).—Nebáj, Depart. Quiché, alt. 7,000*, Apr. 1892, 
Heyde & Lux, (ex Pl. cit. 3,034). 
RUBUS TRILOBUS Mog. et Sessé, var. Guatemalensis 
Focke.—Branches, petioles and under surfaces of the young 
leaves slightly pubescent, not so hairy as in the typical plant. 
Leaves broader than in type, slightly three-lobed; base of the 
terminal lobe often broader than its length, the lateral ones 
very short or indistinct.—Volcan de Agua, alt. 8,000", June 
1892, Dr. W. C. Shannon, U. S. A., (ex Pl. cit. 3,631). 
Rubus superbus Focke.—Rami suppetunt duo florentes. — 
Rami cum petiolis tomentoso-pubescentes, sparsim et minute 
aculeati. Stipulae petiolares parvze filiformes. — Folia ternata, 
foliola omnia petiolulata, subcoriacea, crebre et argute ser- 
rata, utrinque in nervis pilosa, ceterum glabriuscula, supra 
nitida, subtus opaca; foliolum terminale ellipticum, longe acu- 
minatum, basi rotundatum, in utroque latere 8—10-nervia; la- 
teralia paullo minora similia. Inflorescentia sat ampla, 
elongata, inferne folio uno ternato et altero simplici przedita, 
subracemosa vel ramulis inferioribus trifloris paniculata. 
Rhachis cum pedunculis tomentoso-hirsuta, minute aculeata; 
bractez: lanceolatae, parvae, tomentosa. Pedicelli sepalis 
multo longiores, laterales in ramulis trifloris approximati, sed 
non oppositi. Flores spectabiles; sepala ovata, concava, ut- 
rinque cano-tomentosa. Petala magna, obovata, unguiculata, 
sepalis duplo vel triplo longiores. Stamina numerosa, stylos 
superantia, post anthesin patentia. Carpophorum hirsutum; 
carpella numerosa, styli apice clavati stigmate magno coron- 
ati.—The specimens were gathered in an old cornfield, and 
their growth may therefore have been more luxuriant than it 
would have been in other places. The size of the flowers is 
" much greater than in any of the allied species, their diameter 
in a dried state being about one and one-half inches.  Not- 
withstanding the imperfect knowledge of the plant there can 
be no doubt that it is sufficiently distinct from all described
