ON SOUTH-AMEEICAN APOCTlSrACETE. 19 



opposite leaves, a short axillary raceme with few flowers of rather small size, a calyx 

 of 5 unequal ohlong sepals, of which 2 are exterior, broader and twice the length of the 

 others, all imbricated ; within, at the base, are numerous minute scales, so united as to 

 appear like a ring denticulated on its margin ; the corolla has a short tube, with a 

 border of 4 or 5 oblong fleshy suberect segments, dextrorsely convoluted in aestivation, 

 the whole marked by many pustular elevations ; stamens alternate with the segments, 

 fixed in the base of the tube, — the filaments being also pustular, the anther-cells parallel 

 placed upon a connective bearing on its apex a large gland ; a disk of 5 free erect lobes, 

 surrounding the base of an oblong 2-celled ovary crowned by a short thick style 

 indusiate at its apex and enclosing 2 rounded stigmata as in Ambellania.

1. PoMPHiDEA SwARTZiANA, nob. : foUis oppositis oblongis, imo obtusis, apice in acumen subacutum 

 constrictis, integris, glabris, chartaceis, utrinque opacis, minutissime pellucido-punctulatis, et 

 granulato-rugulosis, supra flavide viridibus, nervis arcuatim nexis subimmersis, subtus ocbraceo- 

 ferrugineis ; petiolo tenui, limbo 30plo breviore : racemo axillari, pedunculato, abortione 2-floro ; 

 floribus subparvis, pedicellatis, fuscis ; sepalis extus pilosis et pustulatis, squamulis intemis basalibus 

 albis. In Antilles : v. s. in herb. Mm. Brit. Jamaica (Swartz). 



No particulars are given by Swartz : the branchlet is slender, rugulose, with axils 1 in. 

 apart, it is exstipulate : the leaves are 2f-3f in. long, Ij-lJ in. broad, on a very slender 

 petiole 1 line long ; the axillary peduncle is 4 lines long, on the summit of which only 

 2 flowers remain on pedicels, each 1 J line long : the 2 outer sepals are 2 J lines long, 

 1 line broad, the 3 inner ones being 1^ line long, f line broad ; the tube of the corolla is 

 2 J lines long, 1 line broad, its segments 2^ lines long, f line broad: lobes of disk ^ line 

 long ; ovary superior, f line long ; style f line long. 



A note in pencil upon the specimen states, " Sepals 4-5 ; petals 4-5 ; fruit a 4-5-locular 

 capsule:" the former are probably as much in error as the latter, which cannot be a 

 true statement ; for I found the ovary to be 2-celled, and this is confirmed by the 2-lobed 

 stigma.
