Schizanthus porrigens ; ; pedicellis fructus patentibus distichis rectius- 
culis (corollze labio inferiore pallide purpureo). —Graham, MSS. 
Plant reaching to the height of three feet, and spreading its numerous patent 
branches to an almost equal diameter; the stem and branches covered 
with glandular hairs, from the extremity of which a strong acid is distil- 
led. Leaves largest near to the base of the plant, gradually becoming 
smaller upwards, some of them four or five inches long, bi-tripinnate, 
slightly hairy, obscurely veined, the ita aaa with the 
lobes acute. 
Flowers very numerous, rather distantly nek and sitalaeds in a deschoas 
manner upon long zig-zag, slender, spreading, glanduloso-hirsute, termi- 
nal and lateral racemes. Pedicels about an inch long, slender, patent, 
nearly straight, having at the base two very small oblong bracteas. 
Calyx quinquepartite, the segments linear, erecto-patent, glandular, green. 
Corolla very nearly of the same shape as that of S. pinnatus, but with 
the middle segment of the upper lip not so deeply notched, and the mar- 
gins everywhere less toothed or erose. Of the upper lip the purple hue 
is much paler ; the yellow tint occupies a much larger space in the middle 
segment, and there exist, almost constantly, two deep purple spots, and 
two others, one on each side of the lateral segment ; the lower lip is in- 
variably of a pale purple. Dr Granam has observed, that the two per- 
fect anthers at first lie concealed in the concave part of the inner segment — 
of the lower lip; but that if they are touched, when ripe, they start for-— 
ward towards the style and stigma, and then burst. 
In fruit the pedicels still retain their almost straight direction, and they bear 
capsules very similar to those of S. pinnatus. These appear, however, . 
to be more obtuse at the top, and to have each valve, when burst, notch- 
ed at the extremity; but this, Dr Granam observes, is not a constant 
character. Seeds smaller, rounder, and paler coloured than i in S. pinnatus. 
Under the : re of Gohinentlites pinnatus, given at 
t, 73. of this work, I have mentioned the liability to variation
