138 DE. HOOKEE AND DE. THOMSON'S PEJECTTESOEES 



Dr. Stocks remarks that C. pulchellus, Willd., is cultivated in Belu- 

 chistan ; his specimens so named are not in fruit, and resemble a garden 

 Erysimum very closely. 



We have from Zanskar (alt. 12000-14000 ped.) what may prove a third 

 Indian Cheiranthus : it is a small, woolly, alpine plant, closely resembling 

 C. Himaldicus ; but the leaves are entire, and the flowers white : it is not 

 in fruit. 



5. Atelaktheea, H.f. Sf T. 



1. A. perpusilla, H.f. Sf T. 



Hab. In Himalaya occidentali temperata ad Zanskar ! T. T. (fl. Jun.) 



(v.v.) 

 Herbula minuta, tenuis, annua. 



6. Nastttetium, Br. 



The Indian species of this genus are excessively variable ; and the fol- 

 lowing are, with the exception of N. officinale, perhaps to be regarded as 

 prevalent forms rather than constantly distinct species. 



1. N. officinale (Br. Hort. Kew. ed. 2, iv. 110). Foliis pinnatisectis, 

 superioribus 3-7-jugis, inferioribus trisectis segmentis repandis, petalis 

 albis, siliquis linearibus, valvis costatis. 



Hab. Affghanistan ! Griffith ; Kumaon ad Almora, alt. 5500 ped ! Jac- 

 quemont, Str. Sf Wint. ; mont. Nilgherrie, Gardner ! Kashmir ! T. T. 

 (fl. Jun.) (v.v.) 



Distr. In rivulis temperatis hemisphaerse borealis totse. 



We have specimens of this (the common English Watercress) from several 

 collectors, but doubt its being native. 



2. N. terrestre (Br. Hort. Kew. ed. 2, iv. 110). Suberectum, foliis 

 integris pinnatilobatisve, lobis confluentibus sinuato-dentatis, racemis 

 ebracteatis, petalis flavis, siliquis brevibus turgidis (j—J-")* pedicellis 

 horizontalibus v. deflexis, stylo brevi. 



Engl. Bot. t. 174. — N. palustre, DC. Syst. ii. 191 . — N. Madagascariense, 



DC. I. c. 192.— N. heterophyllum, Don, Prodr. 

 Hab. In Himalaya temperata tota, alt. 4000-10000 ped., a Sikkim!

galia inferiore \ J. D. H. Sf T. T. ; Assam superiore ! Griffith, (fl. tot. 



ann.) (v.v.) 

 Distr. Europa ! Asia borealis tota, Persia ! America borealis ab mare 



arctico ad Mexico ! Am. merid. temp. ! Australia! Nova Zelandia. 



3. N. Indicum (Linn. Mant. 93 ; DC. Syst. ii. 199). Robustum, ramo- 

 sum, foliis obovato-lanceolatis integris v. runcinato-pinnatifidis, race- 

 mis ebracteatis, petalis pallidis v. 0, siliquis teretibus (|— f") pedicellis 

 4-plo longioribus patulis erecto-patentibusve.
