the botanical works of those celebrated naturalists; and 
have consequently omitted the synonym adduced by Baron 
Jacquin from Willdenow as referring to a plant among 
those of Messrs. Humboldt and Bonpland. 
There are wild samples of the species in the Herbarium 
of Mr. Lambert, gathered by Dr. Anderson in the woods 
of the Island of St. Vincent, and recorded as above. There 
is also in the same Herbarium a sample from Jamaica with 
a spike of flowers nearly a foot in length. 
Root perennial. Stems shrubby, 6-8 feet high, about as 
thick as the little finger at the lowermost part, upright, 
woody, with a cracked brownish green bark. Branches op- 
posite, spreading, wide-set, obtusely 4-cornered, smooth, 
green tinged with purple. Leaves opposite, petioled, ob- 
longly ovate, taper-pointed, serrate, waved, wrinkled, 
smooth on both sides, on the upper side of a lively green, 
on the under pale, and when seen through a magnifying 
glass marked with very subtile dots but opaque and reti- 
culately and varicosely veined, the largest ones about 6 
inches long, by 21 broad: petioles about 2 inches long or 
less, ‘smooth, round, depressed above. Flowers very 
shortly stalked, on terminal spikes, in whorls pointing one 
way: whorls 3-6-flowered, each whorl with two minute 
linearly lanceolate withering deciduous subtending bractes.

‘Tieate segments. Corolla deep blue: tube white smooth,

narrowed close under the lips, smooth; lips nearly equal, 
upper lip furred on the outside straight concave obtuse 
-motched at the end, lower lip 3-lobed flat smooth, middle 
‘segment rounded largest, side-ones oblong. Filaments the 
length of the corolla, white, upright after the pollen. has 
been shed, stalked at the middle, connate at the lower 
broader part and sometimes augmented with an anther- 
shaped gland: anthers yellowish, upright, twin. Style the
