2. H. glandulosa. Cav. — Hook, et Arn. supra, p. 303. 
Hab. Between San Bias and Tepic. — Here the bracteas are linear-lanceolate, mucronate, close pressed, 1- 
iierved, opaque, glanduloso-pubescent on the back ; and the usually solitary (rarely didymous) flowers are 
arranged alternately, but pretty close on the short branches so as to form a spike. It is an erect growing 
species. 
3. H. data (n. sp.) ; caule ramisque glanduloso-pilosis, foliis lato-lanceolatis acutis 
ffiqualiter mucronato-serratis glabris utrinque scabris, floribus glomeratis in ramulis 
brevibus, bracteis lineari-lanceolatis mucronatis subintegerriniis opacis uninerviis glandu- 
loso-pilosis. 
Hab. Near the city of Mexico. Bates, in Herb, nostr. — Allied to the preceding, but apparently a much 
taller plant (our specimen, only the portion of a plant, is foot long), and the flowers are constantly glomerated 
at the apices of short branches which are about i an inch long. 
4. H. Cervanfesii. H.B.K. Nov. Gen. Am. 3. p. 164. 
Hab. Realejo. — At p. 303 of this work w'e had expressed a doubt if H Cervantesii was really distinct 
from H. glandulosa. If the present plant be the real H. Cervantesii, it is undoubtedly distinct. It is a pro- 
cumbent, small, straggling, somewhat dichotomous species ; the younger branches only clothed with short, 
glandular down ; flowers glomerated, terminal, but more generally sessile in the axil of the cauline leaves. 
Bracteas opaque, slightly down}', scarcely glandular, lanceolate, but rather broader upward, mucronate and 
mucronato-serrate, 1-nerved, obscurely reticulated. The leaves are ovate, broader than Humboldt describes 
them to be. 
5. H. lupulina (n. sp.); data glaberrima, foliis (nunc oppositis) ovatis breve petiolatis 
duplicato-cartilagineo-serratis aristatis scabriusculis, ramulis gracilibus simplicibus v. 
divisis, bracteatis bracteis profunde cordatis nitidis viridibus reticulatis longe ciliato-den- 
tatis inferioribus reraotis suprerais dense imbricatis involucriformibus floriferis. 
Hab. Realejo and Acapulco. — A most distinct and well marked species to 2 feet high, glabrous in 
every part. The bracteas, f of an inch long and as much broad, are extremely beautiful, and extend for the 
whole length of the smaller branches, the upper imbricated ones only being floriferous, 
6. H. amplectens (n. sp.) ; glaberrima, ramis elongatis superne scabriusculis, foliis oppo- 
sitis sessilibus ovato-acuminatis membranaceis reticulatis duplicato-mucronato-serratis 
scabriusculis superne, in bracteas alternas rigidas nitidas ciliato-dentatas virides reti- 
culatas profundissime cordatas amplexantes supremas imbricatas floriferas transeuntibus, 
calycibus longe aristatis. 
Hab. Between San Bias and Tepic. — Of this very remarkable plant our specimens are from 6 inches to a 
foot in length. Leaves 2 inches long, in remote, constantly opposite pairs ; within from 4 to 6 inches of the 
apex of the branch they suddenly become bright green, cordiform, alternate bractem, an inch long, the upper 
crowded and broader, all of them with so deep and narrow a sinus at the base, that the two lobes embrace 
the stem which thus appears perfoliate.
