 The extreme forms of this most protean species are so dissimilar, that 

 -were they not united by almost all gradations, I should not have dreamt 

 of uniting them. The collection of specimens illustrating these forms in 

 the Kew Herbaria is very large, enabling me to dissect and compare a 

 great amount of material. Roxburgh himself observes (' PI. Coromandel,' 

 i. 60) that the chief difference between his L. arborea and the L. penta- 

 phylla of Retzius consists in the serrated leaves of the former. I certainly 

 do not find any important character in the margination of the leaves au- 

 thorizing me to separate them. The secondary veins and general venation 

 are more decidedly marked in var. a than in var. /3, and the leaves are, 

 perhaps, less coriaceous in texture ; but in subvar. Chinensis we have the 

 leaves of the former with the pistil of the latter. I am not sure if the two 

 forms figured by Roxburgh (Cor. PI. i.) answer to my two races or are both 

 referable to one. Mr. Thwaites, who has most obligingly favoured me 

 with his valuable opinion on some of the important changes which I have 

 proposed in this essay, is of the opinion that the G. arborea and G.penta- 

 phylla of his « Enumeratio * may be safely united. The differential charac- 

 ters to which he called attention in that work he does not find so constant 

 as he had believed them to be. 



2. G. bilocularis, Thwaites, En. PI. Zeyl. 45. Foliis 3-5-foliolatis, 



ovario biloculari glabro in disco incrassato brevi imposito. 

 Loc. Ceylon ! (Maturatte District), Thwaites (C. P. 3362). 

 Frutex. (fide Thw. 1. c). Foliola lanceolata v. anguste trapezoideo- 

 lanceolata, leviter acuminata, apice obtusa, subtus pallidiora, lf-2J unc. 

 longa, 5-8 lin. lata. Panicula axillaris, brevissima, pauciflora. Calyx 

 lobis late ovatis v. triangulari-ovatis. Petala oblonga v. elliptico- 

 oblonga. Stamina alterna breviora,— fide Thwaites ' multum et irregu- 

 lanter dilatata ;' antheris parvis, cordatis. Discus brevis, crassus, ovario 

 paulo latior. 

 Of this species I have seen but a specimen in the British Museum Her- 

 barium, and a small one which Mr. Thwaites kindly sent me with a letter. 

 It appears a distinct species. The axillary inflorescences are extremely 

 reduced, in my specimen hardly ± in. in length. The leaflets are also small.
