FLORA NIGRITIANA. 209 
~ subquadratus ; loculi oblongi marginales. Carpella (v. car- 
pellorum moniliformium articuli inferiores?) circa 6, 31-4 lin. 
longa, siccitate nigra, levia et glabra, oblonga, obtusa cum 
mucrone parvo, sed ex speciminibus haud patet si mucro e 
styli reliquiis superest, vel stipitem indicat articulorum supe- 
riorum arbortientium seu delapsorum. Pericarpium tenuiter 
carnosum, semini arcte adherens. Semen in carpello (seu 
articulo) unicum, loculum arcte implens, exarillatum, raphe 
completa percursum. Testa tenuiter coriacea, integumentum 
interius membranaceum, cum exteriore conferruminatum, intus 
productum in plicas numerosas transversales parallelas, cum 
illas albuminis alternantes et juxta raphin plica angusta 
verticali inter se connexas. Albumen corneum, ruminatum, 
laminas format horizontales numerosas cum plicis integumenti 
alternantes, et irregulariter inter se connexas, lamina verticali 
fere continua raphi opposita ad peripheriam tamen haud 
attingente; lamina altera verticali cum priore ad angulam 
rectam disposita hine inde laminas duo v. plures connectente. 
Prate XVII. Fig. l. flower; f.2. one of the outer petals ; 
Jf. 9. stamen ; f. 4. vertical, and f. 5. transverse section of 
the carpel and seed, (in which, however, by an error of the 
artist, the vertical plates of the albumen are represented as 
continuous with the pericarp) ; f. 6. portion of the surface 
of the connectivum showing the glands; all magnified, espe- 
cially the last.* 
* The sketch made by Dr. Hooker of the only tolerably complete 
flower that he could find, shows that the number of stamens is much 
fewer than in most Uvarie: this circumstance, together with the 
form of the anthers and the apparently monospermous carpels, induced 
Dr. Planchon to suggest that this plant should constitute a distinct 
genus, under the name of Clethrospermum, allied to Ozandra. The 
State of the flower examined was such, however, that it was not pos- 
sible to ascertain whether the number of stamens was really definite, 
nor yet to investigate the structure of the pistils; and although the 
carpels look as if they were complete and constantly monospermous, 
Yet precisely the same appearance is often assumed by the moniliferous 
fruits of some Uvarie, when reduced by accident or by abortion to a single 
articulation, and it is therefore impossible, without further materials,
