666 SUPPLEMENT— CRUCIFERiE. 



Order CRUCIFER^. 



1. CHEIRANTHUS, p. 71. 



1. C. capitatus Dougl. ! (C. asper, Cham. Sf Schlecht. .' fide sp. in herb. 

 Berol.) is the same plant with our Erysimum grandiflorum, Nutt., in which 

 the radicle is certainly incumbent I 



2. C. 1 Pallasii (Pursh !) — A comparison of the specimen in Mr. Lam- 

 bert's herbarium, with Hooker's figure of Hesperis pygma^a, enables us to 

 confirm the correctness of his suggestion. The two plants are certainly 

 identical. The specimen is not in fruit ; hence De Candolle's character 

 ' siliqua teretiusciila,' which seemed to forbid their union, was taken from the 

 appearance of the ovar}'. It must bear the name of Hesperis Pallasii, 

 which has the priority : there is besides another H. pygmsea. 



2. NASTURTIUM, p. 72-75. 



1. N. officinale. — Tampa Bay, Florida, Dr. Leavenworth ! Probably in- 

 digenous. Naturalized in many places. 



2. N. tanacetifolium. — Add syn. N. micropetalum, Fisch. Sf Meyer, ind. 

 sem. St. Petersb. (3) 1837. 



3. N. lyratum. — Oregon, Douglas ! Probably too near N. curvisiliqua ; 

 but the leaves are rather different, and the pedicels shorter. 



4. N. sessilifiorum. — Radical leaves pinnatifid; the lobes somewhat toothed. 

 — Banks of the Ohio, &c. Indiana, Dr. Clapip! 



5. N. sinuatimi. — Add /?. st3de almost none. — Oregon, Mr. Tolmie ! 

 Near N. curvisilitjua, but has larger flowers, longer pedicels, &c. 



4. STREPTANTHUS, p. Ib-ll. 



3. 5. sagittatus. — Instead of ' petals oblong-ovate,' insert, petals cuneate- 

 oblong. 



4. S. angustifolius. — Add syn. S. sagittatus. Hook. Sf Am. ! bot. 

 Beechey, suppl. p. 322, not of Nutt. — Snake Country (Lewis River), Mr. 

 Tolmie ! The specimens are rather larger and more branched than Mr. 

 Nuttall's, and the lower leaves larger ; but there is no other difference. 



10. S. heterophyllus (Nutt.) — Siliques refracted, straight. — It should stand 

 next to S. glandulosus. 



5. TURRITIS, p. 78. 



1. T. glabra P. ? (as well as our plant from the Shore of Lake Superior) 

 is the same with T. stricta, Hook, or very nearly so. — The following species 

 is to be added at the end of the genus. 



10. T. ? lasiophylla (Hook. & Arn.) : stem simple, elongated, strict, 

 hispid below with simple rigid hairs, nearly glabrous above ; leaves oblong- 

 lanceolate, pinnatifid, petioled ; the uppermost linear, entire, attenuate at the 

 base ; calyx rather hairy ; petals linear (yellow), unguiculate ; siliques 

 long, narrowly linear, straight, strongly deflexed. Hook. Sf Arn. bot. Beechey, 

 suppl. p. 320.
