of the Hammersmith Nursery, where our sample flowered 
this summer in the hothouse. 
It was found at Vera Cruz by Dr. Houstoun, by Aublet 
in Guiana; and lastly by Messrs. Humboldt and Bonpland 
in the vallies of Aragua at the height of 240 fathom above 
the level of the sea, and in the province of Popayan at the 
height of 500 fathoms. 
The order Hydrolece was detached from Convolvulacee 
by Mr. Brown; differing by the absence of the remarkable 
wrinkles that distinguish the seedlobes of the latter, and 
the presence of which has been found by that eminent bota- 
nist constantly to announce a fruit with a small and limited 
number of seed, while its absence in the Hydrolee (in truth 
more closely allied to Polemoniacee) announces a fruit with 
an indefinite number of seed. But besides the above tech- 
“nical differences, the habits of the two orders are very dis- 
tinct. 
A subshrubby thorny plant, with a clammy fur; horns 
axilla. Leaves alternate, entire. Flowers both terminal 
and axillary, imbricately folded before expansion. Calyx 
deeply 5—(seldom 6) parted, furred on the outside; hairs 
transparent and jointed; segments lanceolate, pointed, en- 
tire, slightly uneven, l-nerved, green. Corolla campanu- 
lately rotate, smooth, overtopping the calyx; tube short, 
funnelled; limb 5-parted, spreading, segments roundishly 
ovate, obtuse, entire, even, with fanwisely disposed veins. 
Stamens inserted at the middle of the tube, shorter than 
the corolla, even; filaments linearly subulate, membranous, 
smooth, widened at the base; anthers fixed on at the back, 
balanced, oblongly linear, obtuse, sagittately bifid at the 
base, 2-celled, bursting longitudinally. Germen oblong, 
slightly furred at the top, placed upon an orbicular entire . 
smooth disk (fleshy basement): styles 2 (sometimes 3) the 
length of the stamens, filiform, smooth, blue; st¢gmas thick- 
ened slantingly truncated. From the latin of M. Kunth.
