1. Streptanthus glandulosus ; inferne piloso-hispidus, foliis lineari-oblongis dentato-sub- 

 pinnatifidis dentibus glandulosis, radicalibus petiolatis Caul in is profunde sagittatis ara- 

 plexicaulibus, floribus erecto-patentibus (purpureis) secundis, siliquis longe linearibus 

 patentibus curvatis valvis reticulatis uninervibus. Hook. Ic. PI. 1. t. 40. Torr. et Gr. Fl. 

 I. p. 77. 



Quite different from the S. maculatus, Nutt.,from the obtusifolius. Hook. Bot. Mag. t. 331 7, as well as from 

 the S. hyacinthoides. Hook. Bot. Mag. t. 35 16. The lower part of the plant is always more or les3 hispid, 

 the leaves pinnatifid (the uppermost ones sometimes excepted), with the teeth or segments terminated by a 

 gland ; the flowers (of the same colour as the last-mentioned handsome species) never drooping, but secund ; 

 the siliqua always curved, glabrous. 



2. S. sagittatus ; subglaber, foliis radicalibus spathulatis caulinis sessilibus sagittatis 

 integerrimis acutis inferioribus oblongis superioribus linearibus, floribus siliquisque erectis, 

 petalis obovatis longe tenuiterque unguiculatis Nutt. in Torr. et Gr. Fl. 1. p. 76. 



Hab. Snake Country, about Thomas' Fort. (Tolmie.)— Kn erect, rather stout plant, a foot to 18 inches 

 high, glabrous, except in the petioles of the lower leaves, which are distantly ciliated. Stem-leaves strongly 

 sagittate, in our specimens 4-5 inches long ; but in general 2-3 inches. 



3. S. flavescens -, pilosus, foliis lineari-oblongis inferioribus petiolatis dentato-pinnati- 

 fidis dentibus glandulosis caulinis sessilibus integerrimis, floribus erectis (flavescentibus,) 

 petalis linearibus acutis, siliquis (immaturis) erectis hirsutis. Hook. Ic. PI. t. 44. Torr. et 

 Gr. Fl. I. p. 77. 



The few specimens of this plant in our collection appear to have the habit and character of Streptanthus. 

 They are small, 6-8 inches high; simple, unbranched ; the cauline leaves sessile, but not amplexicaul, nor in 

 any way auricled at the base. The flowers are yellow, but the anthers have a purplish tinge. Germen and 

 young fruit (which is erect) hairy ; style evident ; stigma capitate. 



1. Hesperis Menziesii. (Tab. LXXV.)— Hook. Fl. Bar. Am. I. p. 60.— Phcenocaulis 

 cheiranthoides. Nutt. Torr. et Gr. Fl. I. p. 91. 



Hab. Pine Creek, in the Snake Country. (Tolmie.)— Very fine specimens of this plant are in the beauti- 

 ful collection of Mr Tolmie, from the Snake Country, which enable us to give a figure of it. Radical leaves 

 large, oblongo-spathulate, hoary, with minute, dense, stellated down, tapering into petioles, which are dilated 

 at the base, quite destitute of pubescence, glossy, and of a bright straw-colour. Scapes, as thev may be 

 called, (rather than stems,) scarcely twice the length of the root-leaves, nearly glabrous, as are the small 

 oblong leaves which they bear themselves. Corymbs of many large bright purple flowers. Youn- siliqua; 

 spreading.* =

' Since the above was in type, we have had the pleasure of seeing the fruit of this beautiful plant, sent to Dr 

 Boott by Mr Nuttall, as his Phcenocaulis cheiranthoides. This fruit indeed differs (as may be seen from that which 

 we have now added to our figure) from Hesperis (we more particularly allude to H. aprica), in the pods being 

 broader, fewer, about (3)-seeded, the seeds without margin; and in having the cotyledons accumbent; thou-h in 

 our seed, which had a third imperfect cotyledon, the cotyledons were incumbent. In every other respect the flowers 

 and the fruit quite agree with Hesperis, on which account we are led, for the present, to continue it in that genus.
