has been followed by Messrs. Humboldt and Bonpland, 
in their “ Plantes Equinoxiales;” while Catnasra has been 
substituted for the generic name of our plant, in com- 
pliment to Don Josef Caldas, an eminent botanist native of 
Popayan in New Granada, now living. 
A tender herbaceous fibrous-rooted annual? diffusing 
a strong smell, to us like that of the common Horehound. 
Stem. 1-2 feet high, upright, branched, branches ascend- 
ing, scattered, covered, as well as the foliage, with a 
close pubescence of sub-viscid transparent glandular mi- 
nutely’ articulated erected hairs. Lower cauline leaves 3-4 
inches long, scattered, petioled, oblong, sublyrate, acute, 
serrate; upper rameous ones opposite, subsessile, elliptic- 
lanceolate, entire, one of each pair alternately flowerbear- 
ing, the whole marked with many near parallel transverse 
varicose subascending nerves, issuing from each side of a 
middle vertical rachis. Flowers peduncled, terminal and 
axillary in distant alternate pairs, parallel, upright, shorter 
than the foliage. Calyv herbaceous, tubular and tapering 
downwards, narrow, pentagonal, with sharp prominent 
angles, segments 5, angularly ovate, pointed, upright. 
Corolla \ess than an inch in depth, subbilabiately hypocra- 
teriform, tube bent at the faux where it widens, limb in- 
clining forwards, segments obcordate and oblong, two 
upper largest converging, with a white figured spot at the 
base of each, Stamens connivent, . projecting, declining, 
about equal to the limb; bearded at the base. Germen small,

Native of Mexico; introduced since the publication 
of the last edition of the Hortus Kewensis, by Mr. William 
Anderson, curator of the Chelsea Physic Garden. Mr, Ed- 
‘wards was fayoured with the specimen from which the draw- 
ing was made, from Mr. Aylmer Bourke Lambert’s collec- 
tion at Boyton, Wiltshire, in January last. Willdenow 
says, if kept in the stove in winter and in the open air in 
summer, it will ripen the seed. Mr. Lambert’s gardener 
observes, that. it is peculiarly liable to be infested with the 
red spider, and that it is only to be rescued from that plague 
of the hothouse by copious waterings over the head of the 
plant.
