52 PHANEROGAMIA. 



inter folia supremo, sessili (petalis spathulatis albis unguiculatis) , 

 fructifero nunc breviter exserto; siliculis longe pedicellatis ovatis 

 incanis stylo brevi apiculatis. 



D. cryptantha, Hook. f. Fl. Antarc. p. 234, adnot. 



Hab. Between Culnai and Casa Cancha, high Andes of Peru ; in 

 the alpine region. 



Stems depressed, numerous from a perennial root, ccespilose, the tufts 

 from half an inch to 2 inches long, crowded, covered with the imbri- 

 cated leaves. These are canescently tomentose, as is the whole plant 

 more or less, obovaie, obtuse, concave, thickish, 2 or 3 lines long. 

 Raceme few-flowered, abbreviated, and almost sessile among the leaves 

 at the summit of the branches when in flower (the flowers small, with 

 spatulate and unguiculate ivhite petals) ; in fruit raised, in our speci- 

 mens, upon a peduncle of from 2 to 4 lines in length, and therefore 

 more or less exserted beyond the leaves; the pedicels somewhat 

 umbellate, a line or a line and a half long. Silicle ovate, canescent, 

 about 2 lines in length, tipped icith a very short style. 



The plant described by Dr. Hooker (from Cerro Pasco, in the same 

 district) is in flower, and with some barely mature fruit; in which 

 state it deserves the name of D. cryptantha. Our specimens are not 

 only in fruit, but far advanced, the valves and seeds having fallen 

 from the pods ; and in this state the peduncles are more or less ex- 

 serted. The species properly belongs to the second section of Dr. 

 Hooker's revision of the South American Drabce; so that his first 

 section might be suppressed. 



2. Draba Macleani, Hook, f 



D. incano-tomentosa ; caide brevissimo diviso e radice perenni; foliis 

 confertis obovato-oblongis obtusis; pedunculo elongato nudo; corymbo 

 subcapitato; floribus parvis breviter pedicellatis albidis; silicidis gla- 

 berrimis ovatis in stylum brevissimum attenuatis, valvis planis.
