WESTERN TROPICAL AMERICA. 149 
opposita, bracteis parvis suffulta——Frutices Americe meridionalis, ramis elongatis involucrisque 
glanduloso-pilosis, foliis ovatis ovalibusve petiolatis subhirsutis minus glandulosis, spicis longis, invo- 
lucris distantibus, bracteis involucro multo minoribus oyato-subrotundis mucronatis. | Genus inter- 
medium inter Hypoestem et Diclipteram, et maxime id quidem insigne eo, quod involucrum bivalve 
Dicliptere hic veluti in utriculum oblongum apice bidentatum coalescit, neque vera eum ab omni 
latere, sed ab altero margine tantum clausum, ab altera parte vero discretis marginibus rima apertum. 
H. insularis, involucris acutis, caule inferne tereti superne tetragono.—Foliorum lamina 4 poll. longa, 
utrinque acuta, integerrima, pilosa, nitida, viridis, costis senis parum prominulis; petiolus pollicaris, piloso- 
glandulosus. Racemi circiter tripollicares, laterales oppositi arcu incurvi. Involucra 4} lin. longa, obconoidea, 
apice bidentata, pubescenti-glandulosa. Calyx vixlin. 1 longus. Corolla tenera, infundibuliformis, 3 lin. longa. 
Stamina limbum 14-2 lin. longum equantia, erecta. Stylus longior. Capsula 3 lin. longa, straminea, glabra. 
Seminum sete dorsales statu humido stricte, in sicco corrugate, laxe, lanam referentes; constant singule e 
pluribus cellis elongatis conjunctis, in quibus hine inde fibre spiralis vestigia vidisse puto; cellule interiores 
obscuriores sunt quam relique. In superficie setarum sub inde denticuli prominent.

677. Henrys Barclayana, Nees ab E., sp. n., involucris obtusis, caule quadriquetro.— 
Manzanilla Bay. 
Folia brevi-petiolata. Involucra densissime pubescenti-glandulosa, apice obtusa, scil. foliolis conjunctis 
haud mucronatis sed apice rotundatis. 
678. BLecHUM Linnei, Nees ab E.—Panama to Guayaquil. 
679. Dicurptera multiflora, Humb. et Kunth.—Guayaquil. 
680. Dicurprera confinis, Nees ab E., sp. n., caule sexangulari glabro novello sparsim piloso, 
foliis oblongis acuminatis basi acutis longe petiolatis utrinque lineolatis glabris, floram umbellis 
sessilibus in spicam terminalem foliosam transeuntibus, bracteis late ovatis cuspidato-acuminatis 
glabris ciliatis trinervibus nervis lateralibus trifidis——Guayaquil. 
Differt a D. peruviana caule fere glabro nec nisi pilis raris adsperso, foliisque angustioribus et bracteis, 
preeter harum cilia, fere omnino glabris. An var. ? 
681. Dicurprera unguiculata, Nees ab E., sp. n., caule geniculato obsolete angulato apicem 
versus pubescentia brevi reversa scabro, foliis ovatis utrinque acutis longe petiolatis lineolatis margine 
hispido-scabris, florum umbellis sessilibus axillaribus vel in spicas axillares terminalemque compactis, 
bracteis inaequalibus scabris ciliatis trinervibus, superiori suborbiculari aristato-cuspidata basi longe 
cuneiformi, inferiori duplo minore spatbulato-lineari truncata aristato-cuspidata.— Guayaquil. 
Caulis videtur procumbens et diffusus; valde est geniculatim flexus, inferne glaber et fere teres. Folia 
cum petiolo semipollicari 2-8 poll. longa, 1-1} poll. lata, acumine arguto predita et basi etiam acnta, 
Bracteee basi lutez, subtilissime pubescenti-scabree, mucrone longo setaceo cuspidate, ciliate ; superior 5 lin, 
longa, inferior 8 lin. etea arcte incumbens. An eadem ac D. pilosa H. et Kunth. ? repugnant autem “ bractee: 
villose,” et in descriptione: ‘‘tres, quarum laterales lineari-subulate,” missa omnino bractea inferiore, que 
singulari sua structura oculos effugere nequibat.
