230 THE LADIES' FLOWER-GARDEN 
succeeded in finding a withered specimen on the banks of the Ohio, from which he procured some seed. In 1826 
a kind of Collinsia was found on the banks of the Columbia, which was at first supposed a diiFerent species, and 
was described in the Bot. Reg. as Collinsia grandijiora ; but it has been since found that the differences 
discoverable between the specimens are not sufficiently constant to be relied on. The plant is quite hardy and 
will grow in any soil or situation, but it does best treated as directed for L^tosiphon. When sown in spring it 
should be in February, as, if the sowing be delayed till the latter end of March or the beginning of April, the 
plants generally wither without flowering. All the CoUinsias bear cold much better than heat. A rather 
curious proof of the hardiness of this species happened a year or two ago in the garden of a friend of ours. Some 
Collinsia ■eema had been sown in the autumn, and after it had flowered the plants were pulled up and thrown 
on a heap of very stifi" clay which had been provided for puddling a pond. This was about November, and in 
April, when the clay was wanted for use, it was found covered with a splendid mass of flowers of this species, 
which were as fine, and as brilliant in colour, as though the seeds had been sown in the best prepared bed. This 
species was introduced in 1826, and seeds of it are common in the seed-shops both as C. verna and C. grandijhra.

Flow. G.ird. 2nd Ser. t. 307 ; Bot. Card. No. 689 ; Paxt. Mag. of 
Bot. vol. 3, p. 195 ; and our fig. 3, in Plate 41. 
Specific Character. — Stem erect, downy. Leaves glabrous, ovate- 
lanceolate, subcordate at the base. Pedicels verticillate, racemose. — 
(G. Don.) 
Description, &c. — A very showy annual, but one which differs so much, according to the soil and situation 
in which it is grown, as scarcely to be recognised as the same plant. If the seeds are sown in autumn, as 
directed for the Leptosiphon, and transplanted, or rather removed, in spring to a bed of rich and rather strong 
soil, where the roots will be shaded from the sun and kept rather moist, the plant will grow two feet high with 
a strong erect stem, and will produce a profusion of splendid flowers, large in size and clear and brilliant in 
colour ; while if the seeds are sown in April or May, about the usual time of sowing flower-seeds, the flowers 
will be poor and the stems weak ; and if the roots are exposed to the sun, the plants will wither and die without 
any apparent cause, in the same manner as those of Nemophila insignis do under similar circumstances (see p. 
217). This species differs considerably from C. verna, particularly in the shape of the leaves, and in the colour 
and disposition of the flowers. It is a native of California, where it was discovered by Douglas in 1833 ; and 
notwithstanding its recent introduction, seeds are already common in all the seed-shops.

Kngravings. — Bot. Mag. t. 3695 ; and our ^^. 2, in Plate 41. I a glandular pubescence. Segments of the corolla rounded at the apex, 
Specific Character. — Lower leaves trilobate ; upper ones ovate- crenate, middle tube of the lower lip subacute, border of the upper lip 
Mttminate. Peduncle shorter than the flower. Calyx covered with I nearly entire. — (^Graham.) 
Description, &c. — This species very closely resembles C. hicolor, but the flowers are larger, and difl'er 
slightly in the colour. The lower leaves are also three-lobed ; but altogether the botanical differences do not 
appear more than were supposed to exist between C. vema and C. grandijiora. The general appearance of the 
plants, however, is tolerably distinct. The culture of both species is the same. C. heterophylla is a native of 
California, where it was found on the banks of the Columbia, and it was introduced in 1838. Seeds may be had 
at Carter's, but they are at present rare in the seed-shops.
