2. H. glandulosa. Cav.—Hook. et Am. supra, p. 303. 



Hab. Between San Bias and Tepic— Here the bracteas are linear-lanceolate, mucronate, close pressed, 1- 

 nerved, 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. elata (n. sp,); caule ramisque glanduloso-pilosis, foliis lato-lanceolatis acutis 

 aequaliter mucronato-serratis glabris utrinque scabris, floribus glomeratis in ramulis 

 brevibus, bracteis lineari-lanceolatismucronatis subintegerrimis 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 1 £ foot long), and the flowers are constantly glomerated 

 at the apices of short branches which are about $ an inch long. 



4. H. Cervantesii. H.B.K. Nov. Gen. Am. 3. p. 164. 



Hab. Realejo. — At p. 303 of this work we 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 downy, 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.); elata 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 remotis supremis dense imbricatis involucriformibus floriferis. 



Hab. Realejo and Acapulco A most distinct and well marked species 1£ 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 bracteae, 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.
