happy to announce,—that the species published at folio 1082 
of the present volume is confined to the rocks in the vicinity 
of the ocean; while the subject of this article is found in 
the situations above described; and the plant figured by 
Nuttall, in the Journal of the Academy of Natural Sciences 
of Philadelphia, as his Collinsia verna, is chiefly produced 
upon inland rocks. 
Of the last-mentioned plant, Mr. Douglas gathered an 
abundance of specimens, from which, and the figure above 
referred to, it appears that C, verna is distinguished by its 
stems being much less branched than those of C. grandi- 
flora, by its peduncles being longer than the flowers, its 
calyxes downy, with much less finely pointed divisions, 
and shorter in proportion to the flower, and the segments 
of the flower, which is far less beautiful, being blunt only, 
not dilated and retuse. The margin, moreover, of the 
corolla of C, grandiflora is always crisp, or even tooth- 
letted,—a character which our artist has omitted in the 
figure ; while that of C. verna possesses this peculiarity in 
a very slight degree. The corolla of C. verna is white 
in the parts which are purple in C. grandiflora. 
The specific character of C. parviflora, as given above, 
at fol. 1082, may be contrasted better with that of the two 
other species. We therefore subjoin it in an amended 
form, along with that of C. verna.* 
Stem-erect, branched, 6 inches or a foot in height, 
pubescent. The lower J/eaves spatulate, the upper oblong- 
linear, smooth, sometimes entire, sometimes toothletted. 
Flowers whorled, very numerous, and shewy. Peduncles 
smooth, filiform, twice as short as the flowers. Calyx 
smooth, with very finely pointed segments, which appear 
as if aristate. Corolla with the tube and upper lip purple, 
the lower intensely blue; the segments dilated, crisp in a 
crenulate way at the margin, retuse; the lower inter- 
mediate one being very small. 5 J. L.
