species. Among the brambles (Zuóatus) of Mexico and 
Central America R. fagzfolius, R. scandens, R. Schiedeanus 
and A. coriifolius bear their flowers in compound racemes; AK. 
adenotrichos, R. Bogotensis and allied forms are distinguished 
by their copious glandular bristles; K. safzZus may be easily 
distinguished by its short racemose inflorescence and prickly 
peduncles; in R. Aumistratus the flowers are usually solitary; 
R. floribundus has soft tomentose leaves; AR. Lzebmann:z, R. 
tiligfolius and R. Uhdeanus have small flowers and very hairy 
leaves. (W. O. Focke.)—San Miguel Uspantán, alt. 6,000",

Rubus poliophyllus Focke, —(R. cozzzfolus Focke in Enu- 
mer. Pl. Guatemal. qu. edid. J. D. S. Part. 11. p. 19; non 
Liebm.)—Rami teretiusculi, tomentoso-puberuli, aculeis e 
basi lata compressa recurvis armati, florentes et terminales et 
laterales. Folia inferiora quinata vel subquinata, superiora 
ternata, suprema sape simplicia; stipulee petiolares, parva, 
filiformes. — Foliola omnia petiolulata, subcoriacea, mollia, 
argute serrulata, superne stellulato-tomentella, subtus cano- 
tomentosa, in utroque latere 8—10-nervia; terminale ovato-el- 
lipticum vel oblongum, breviter acuminatum, lateralia minora 
similia. Inflorescentia mediocris, multiflora, divaricata, pan- 
iculata; rhachis ramuli pedicellique cano tomentosi, aculeis 
parvis raris setisque glanduliferis sparsis longis interdam quo- 
que brevibus intermixtis muniti. Ramuli inferiores axillares, 
erecto-patentes, racemoso-pluriflori, sequentes bracteolis tri- 
fidis tomentosis suffulti, patentes, supra medium 3-7-flori. 
supremi bracteis simplicibus lanceolatis muniti, approximati, 
vulgo uniflori, florem terminalem superantes. Sepala ovata, 
breviter mucronata, utrinque tomentosa, post anthesin paten- 
tia. Petala (mediocria vel parva ? ), decidua, alba. Stamina 
numerosa, stylis, ut videtur, zquilonga. — Carpophorum pilo- 
sum; carpella sat numerosa, glabra. Fructus hemisphaerici, 
nigri, ex acinis ca. 20 compositi.—This is the same spe- 
cies that I supposed at first sight to be a variety of A. corzi- 
folius. Having seen more specimens I have no doubt now 
that it is quite different; in R. corzzfo/ius all the branchlets of 
the panicle bear their flowers in racemes and not in cymes. 
It is much more difficult to distinguish the new plant from 
— AR. Liebmannii and R. Uhdeanus ; itsleaves, however, are much 
more tomentose than in the allied species. A. Lzebmannii 
has a short drooping panicle and pink petals, R. UAdeanus a
