ON SOUTH-AMEEICAN APOCTNACE^. 17 



the tube of the corolla is 7 lines long, 2| lines in diam. ; the border-segments 11 lines 

 long, 3 lines broad, thick, fleshy, distinctly auriculated at the base, and so firmly con- 

 voluted sinistrorsely that they are with diificulty unrolled : the stamens are 4 lines long ; 

 the urceolate disk is 1 line high, 2 lines broad ; the globular ovary is 1^ line in diam. ; 

 the slender style is 4 lines long ; the clavuncle, with its glands, is 2 lines long ; the 2 

 stigmata 1 line long, ^ line broad. The fruit, according to Aublet, is about the size of a 

 citron, of a greenish colour when not quite ripe ; it contains a single seed, as in Zschokkea 

 and Lacmellia, the structure of which is unknown. 



A drawing of the above species, explaining its floral structure, with a figure of the 

 fruit, are given in Plate II.

A species very similar in habit to the preceding, but different in many charac- 

 ters. Its aggregated leaves are 15* in. long, 6 J in. broad, on a thick villous petiole 

 only ^ in. long: it has about 12 densely aggregated terminal flowers, upon short 

 villous pedicels, 1 line long, growing out of a cluster of very short acute bracts : 

 the calyx is 6 lines long, 3 lines broad, somewhat gibbous at base ; the tube of the 

 corolla is 5 lines long, its border-segments 5 lines long ; the aciculated anthers 4 lines 

 long, on filaments 1^ line long, fixed to the bottom of the tube, and dorsally attached to the 

 anther J line above its cordate base ; the style, rising from a tuft of hairs on the summit 

 of the ovary, is 3^ lines long, is thickened above by a clavuncle 1 line long ; the stigmata, 

 1^ line long, are lanceolate and erect : disk 1 line high, 2 lines broad ; ovary depressed- 

 globose, ^ line in diam., its 2 cells too, minute to ascertain the number of ovules : several 

 spiral thi-eads were observed in the fleshy substance of the segments of the corolla. 



Ceeatites. 



This genus, well elaborated by Dr. Solander, has escaped the notice of botanists, owing 

 to the knowledge being only possessed by few of the rare books in the Banksian library, 

 where the scarce work of Solander is deposited — a volume which minutely describes many 

 rare Brazilian plants, well illustrated by several beautiful coloured drawings. Ceratites 

 was founded on a single species, collected by him in Bio de Janeiro in 1768, the typical
