*GAMBELIA.+ 
Natural order, ScropnutArin«%. Tribe ANTIRRHINES. 
Calyx 5-parted, nearly equal. Corolla hypogynous, the tube cylindrical, saccate at the base, orifice 
narrowly pervious, the border bilabiate, the palate rather prominent, smooth; upper lip erect, the 
lower spreading, all the segments nearly equal and oblong. Stamina four, arising from the base of the 
corolla tube, included, didynamous:: no sterile filament: anthers bilocular, oblong. Ovarium bilocular, 
with many ovules, seated upon a glandular torus. Style simple, clavate, entire. Capsule subglobose, 
2-celled, opening below the summit by two or three irregular apertures. Seed, [not seen.]—A 
spreading bush, with verticillate, entire, coriaceous leaves, and axillary and terminal conspicuous 
scarlet flowers. Allied to Galvezia, but with a prominent palate and a saccate spur at the base of the 
corolla. 
G. SPECIOSA. 
A bush about three to four feet in height, full of bright scarlet flowers. The older 
branches covered with a smooth grey bark, all of them cylindric. The younger 
branches, leaves and flowers more or less hairy, with a soft pubescence. Leaves 
rather small, coriaceous, ternate, verticillate, and apparently evergreen, with a few 
obscure reticulated vessels running over the under surface ; their form oblong, rather 
obtuse, entire and attenuated at the base into a short peduncle: there are no stipules 
or bractes, though the leaves diminish to a very small size as the terminal 
inflorescence advances. Length of the leaves about one and a half inches, the 
breadth about half an inch. Peduncles axillary by threes, shorter than the lower 
leaves. Calyx unequal, 5-parted, the segments linear-lanceolate. Corolla about an 
inch in length and tubular, with a conspicuous saccate spur at the base; the border 
personate, the lower lip 3-lobed, with a somewhat prominent smooth palate; upper 
lip 2-lobed, somewhat erect, and deflected at the sides. Stamens didynamous, arising 
from the base of the tube, the pairs a little unequal, the filaments with a chaffy down 
at the base. Style a good way shorter than the corolla, gradually clavate above and 
perfectly entire, and a little curved at the summit.: a glandular torus round the base 
of the germ. Capsule subglobose, hirsute, two-celled, opening below the summit by 
two or three irregular roundish foramina ; the placenta attached chiefly to the centre 
of the dissepiment. The imperfect seeds appear to be narrow and angular, but the 
perfect séed I have not seen.
