1. Turritis? lasiophylla; simplex elongata stricta inferne pilis simplicibus rigidis hispida 
superne glabriuscula, folifs oblongo-lanceolatis pinnatifidis petiolatis supremis linearibus 
integerrimis basi attenuatis, calycibus subpilosis petalis, linearibus (flavis) unguiculatis, 
siliquis (immatuvis) longis angusto-linearibus strictis arete deflexis. 
A very distioct species, 1 ^ foot to 2 feet high, very straight, unbranched ; lower leaves on long petioles, 
pinnatifid with sharp unequally sized teeth. Petals yellow, linear, about half as long again as the calyx. 
Young pods very narrow, not in the least curved, deflexed. 
1. Arabis hlepharophylla ; foliis utrinque nudis marginibus pilis albis rigidissimis sim- 
plicibus vel furcatis ciliatis, radicalibus obovato-spathulatis caulinis oblongis sessilibus, 
calyci foliolis ellipticis obtusis superne stellato-pubescentibus, petalis obovatis in unguam 
attenuatis (purpureis). 
’ A small plant, three or four inches high, with a perennial root. Stem simple. Radical leaves several, 
spreading, an inch or more long, naked on both sides, those of the stem hispid on the costa beneath ; all of 
them margined with white, singularly rigid, simple or forked hairs. Calyx membranaceous, slightly coloured, 
and scariose at the margin, half of the length of the petals, which appear to be purplish. 
1. V achy integrifolium ; glaberrimum, foliis lineari-lanceolatis integerrimis sub- 
glaucis, floribus fructibusque dense corymbosis, siliquis angusto-linearibus teretibus toru- 
losis, stylo brevi, stigmate parvo capitato. (Tab. LXXIV.) — Nutt, in Torr. et Gr. 1.

Hab. Snake Country. Blackfoot River. (^Tolmie .) — Of the genus of this we are very doubtful, the fruit 
not being ripe, though the siliquse seem fully formed. But these siliquse are quite terete (the valves being con- 
cave), singularly torulose or moniliform, and there is a great disposition (when saturated with moisture) in their 
valves, not in the rest of the seed-vessel, to break at the joints. The root is perennial ; from the summit 
of which arise one or more stems 12-14 inches high, branched at the base, and above also bearing many short 
leafy branches, each terminated by a dense corymb of pale purple flowers. Calyx glabrous, membranous. 
P,etals obovato-lanceolate, with long claws. The fruit likewise forms corymbs, about an inch long, slightly 
curved upwards. Seeds in a single row, oblongo-ovate, minutely dotted. Embryo unformed in our specimen.*

* After the above had been printed under the name of Cardamine ? torulosa. Hook, et Arn., authentic specimens in 
Dr Boott’s Herbarium have proved to us that this is the Pachypodium integrifolium, 1. c. The genus is founded upon 
Macropodium, laciniatum. Hook. Bot. Misc. 1. p. 341. t. 68. (which has much compressed pods) ; and is separated 
by Mr Nuttall from Macropodium (Br.) on account of the incumbent cotyledons and narrower siliquae, with shorter 
stipes. The present plant has the siliquae perfectly terete and torulose, and scarcely differs from Cardamine or 
Arabis, except in the direction of the radicle, which indeed, though dorsal in its origin, is applied obliquely to the 
cotyledons.
