Mr. J. Miers on Diclidanthera. 133 



The following is an emended character of the genus, based 

 upon my own observations : 



Diclidanthera, Mart. Pluchia, Veil, — Flores hermaphroditi. 

 Calyx in imo hemisphsericus et hinc cum disco cupuliformi 

 carnoso adnatus, superne in sepala 5, linearia, obtusa, sequa- 

 lia, utrinque pilosa, sestivatione quincuncialiter imbricata, 

 decidua, divisus. Petala 5, sequalia, sepalis 2-3-plo longiora 

 et alterna, margine disci enata, et ultra medium ad tubum 

 staminiferum agglutinata, hinc pseudo-gamopetala, margini- 

 bus contorsive imbricatis, sinistris connatis, dextris liberis, 

 ciliatis, et carinis totidem obliquis efFormantibus, supra tubum 

 omnino libera, apicem versus paullulo latiora, obtusa, sub- 

 patentia, sestivatione quincuncialiter imbricata. Stamina mo- 

 nadelpha, cum petalis orta, filamenta in tubum integrum, 

 cylindricum, elongatum, tenuissime membranaceum, ad pe- 

 tala arete agglutinatum, 10-nervem, coalita: antherm 10, 

 sequales, uniseriatse, in marginem tubi filamentorum inscrtse, 

 erectse (et ut videtur in fauce tubi corollse sessiles), reni- 

 formi-ovatse, 2-loculares, loculis collateralibus sine connectivo 

 coalitis, transversim 2-valves, rima oblique hippocrepica de- 

 hiscentes, valva postica paullo majore erecta, antica hiante 

 deflexa et e basi pendula. Pollen globosum, vittis 4 notatum, 

 et transversim creberrime lineatum. Ovarium parvum, sub- 

 globosum, glabrum, stipitatum, obsolete 5-sulcatum, 5-locu- 

 lare ; ovula in quoque loculo bina (uno minore et effoeto), ad 

 axin centralem infra apicem suspensa, micropylo supero, ra- 

 phide ventrali. Stylus simplex, pilosus, stamina excedens. 

 Stigma parvum, clavatum, breviter 5-lobum. Drwpa globosa, 

 cupula parva calycina suffulta, sicca, coriacea, indehiscens, 

 5-locularis, 5-sperma, aut abortu 2-3-sperma. Semen sus- 

 pensum, ovatum, compressum ; integumenta 3, extimum fus- 

 cum, retrorsum pilosum, pilis albidis, sub lenti rugoso-punc- 

 tatum, intermedium rubellum, nitidum, crassiusculum, vertice 

 hilo notatum, basi chalaza signatum, intimum membranaceum. 

 Embryo in albumen tenue, carnosum, paullo longius inclusus ; 

 cotyledonibu^ suborbicularibus, subcordatis, planis, foliaceis, 

 viridiusculis, albumini fere sequilatis, et paullo brevioribus, 

 radicula brevi, tereti, supera, summum attingente. 



Arbusculse Brasilienses inte^^tropiccPf ligno duro rigido, ramis sub- 

 sarmentosis, ramulis scepissime pendulis ; folia petiolata, inte- 

 gerrimaj nitida, valde reticulata^ glabra^ in nervis puberula, 

 glandulis paucis scspe in dichotomiam nei^vorum immersis; petiolus 

 in imo articulatus; stipulse bince, acuta, decidua, utrinque e 

 glandula umbilicata orta ; inflorescentia racemosa ; racemi folio 

 brevioreSf in ramulis novellis axillaribus terminates, pluriflori\
