Mr. J. Micrs on Diclidanthcra. 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 

 caruoso adnatus, superne in sepala 5, linearia, obtusa, a?qua- 

 lia, utrinque pilosa, sestivatione quincuncialiter imbricata, 

 decidua, divisus. Petala 5, a?qualia, sepalis 2-3-plo longiora 

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

 staminiferum agglutinata, hinc pseudo-gamopetala, margini- 

 bus contorsive imbricatis, sinistris connatis, dextris libcris, 

 ciliatisj et carinis totidem obliquis efformantibus, supra tubum 

 omnino libera, apicem versus })aullulo 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 : anthera 10, 

 pequalcs, uniseriatse, in marginem tubi filamentorum inserts, 

 crecta3 (ct ut videtur in fauce tubi corolla} sessiles), reni- 

 formi-ovata}, 2-loculares, loculis collatcralibus sine connectivo 

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

 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 effocto), ad 

 axin centralem infra apicem suspensa, micropylo supero, ra- 

 phide ventrali. Stylus simplex, pilosus, stamina excedens. 

 Stigma parvum, clavatum, brcviter 5-lobum. Drupa globosa, 

 cupula parva calycina suffulta, sicca, coriacea, indehiscens, 

 5-locularis, 5-spcrma, 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 rubcllum, nitidum, crassiusculum, vertice 

 hilo notatum, basi chalaza signatum, intimum membranaceum. 

 Embryo in albumen tenue, carnosum, paullo longius inclusus ; 

 cotyledonibus suborbicularibus, subcordatis, planis, foliaceis, 

 viridiusculis, albumini fere sequilatis, et paullo brevioribus, 

 radicula brevi, tereti, supera, summum attingente. 



Arbuscula? Brasilienses intertropicce, ligno duro rigido, ramis sub- 

 sarmentosis, ramulis scepissime pendulis ; folia petiolata, inte- 

 gerrima, nitida, valde reticulata, glabra, in nervis puberula, 

 glandulis paucis sape in dichotomiam nervorum immersis; petiolus 

 in imo articulatus ; stipula} bina, acuta, decidua, utrinque e 

 glandula umbilicata orta ; inflorcscentia racemosa ; racemi folio 

 breviores, in ramulis novellis axillaribus terminates, pluriflori ;
