24 TRIANDEIA. MQNOGYNIA. 



the tube of the corolla short, as in most of the European 

 species, and nearly all have compressed, obtusely triangu- 

 lar seeds, and tuberous roots. Many of the African species, 

 with bulbous roots, have the tube of the corolla remark- 

 ably long-, seeds more or less round, approaching to sphe- 

 rical, and linear grassy leaves.

Calix superior, petaloid, externally hirsute, 

 deeply 6-parted, nearly equal, erect, and persis- 

 tent. Stamina erect, a little unequal. Style 

 declining; stigma minutely trifid. Capsjile 

 round, 3-celled, few-seeded; (3-6 in each cell.) 



Leaves considerably like those ofthe/Ws; sheathing, on 

 tlie stem sessile; flowers paniculate, corymbose, exter- 

 nally pubesftent, internally coloured and petaloid, nearly 

 equal, but the style somewhat declined and thus ap- 

 proaching to the genus WacheJidoi-Jia. The D. Heritiera 

 of the United States, although a very distinct species from 

 the other 4 described as natives of the Cape of Good 

 Hope, can hardly be considered as constituting a distinct 

 genus: it is true, that the stamens are more nearly equal 

 than in the Cape species, but scarcely so, absolutely, with 

 the presence of a declining style. As to the structure of 

 the flowers, they are both merely furnished with a peta- 

 loid calyx, divided down to its base; the Gape species, at 

 least one examined by Jussieu, had a hirsute capsule, 

 crowned by the persistent calyx, of 3-cells, S-valves, 3- 

 seeds, the valves naked in the inside, or without a recep- 

 ticular placenta, with a central 3-sided receptacle, the 

 seeds flat, and peltate. In the Heritieruy there are asjmany 

 as 6 or 7 seeds in each cell, and of a somewhat diiferent 

 form, being round and compressed. It appears, however, 

 probable from the globose form of the capsule in Dilatris, 

 thai there must be a roundish seed, or seeds, as there is no 

 succulent receptacle. The Heritiera has also a roundish, 

 obsoletely triquetrous, capsule. Are there not two spe- 

 cies confounded as the I). Heritiera in the United States?
