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- 
Tical, and linear grassy leaves. 
DILATRIS. Persoon. Lacunanrugss. EI- 
hiott. (Red-root.) 
Calia superior, petaloid, externally hirsute, 
deeply 6-parted, nearly equal, erect, and persis- 
tent. Stamina erect, a little unequal. Style 
declining; stigma minutely trifid. Capsule 
round, 3-celled, few-seeded; (3-6 in each cell.) 
Leaves considerably like those ofthe Jris; sheathing, on 
the stem sessile; flowers paniculate, corymbose, exter- 
nally pubescent, internally coloured and petalwid, nearly 
equal, but the style somewhat declined and thus ap- 
proaching to the genus Wachendorfia. The D. Heritiera 
of the United States, although a very distinet species from 
‘the other 4 described as natives of the Cape of Good 
Hope, can hardly be eonsidered 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- 
~ doid calyx, divided down to its base; the Cape species, at 
least one examined by Jussieu, had a hirsute capsule, 
crowned by the persistent calyx, of 3-céils, 3: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 Heritiera, there are asjmany 
as 6 or 7 seeds in each cell, and of a somewhat different 
form, ma J round and compressed. It appears, however, 
m the globose form of the capsulein Dilatris, 
_ that there must be a roundish seed, or seeds, as there is no
