1 . N. PARviFLORA (Dougl. MSS.), foliis pinnatifidis, lobis paucis latis subden- 



tatis, calycis sinubus breviter appendiculatis, corollis calycem vix super- 

 antibus, placentis 2-ovulatis. 

 Flores parvi. Calycis appendiculi ssepius brevissimi interdum evanidi, rarius 

 post anthesin elongati. Squamae corollinse parvse, angustae. (v. s. sp.) 



Received both from Mr. Douglas and Dr. Scouler from the Columbia. 



2. N. PEDUNCULATA {Doiigl. MSS.), foHis pinnatifidis, calycis sinubus breviter 



appendiculatis, corollis calycem vix superantibus, placentis 6-ovulatis. 

 Habitus, calyx et corolla omnino N. parviflorce. Folia angustiora, lon- 

 gius petiolata, lobis magis integris distinctisque. {v. s. sp.) 



Gathered by Mr. Douglas on the Columbia. 



3. N. PHACELioiDES {Bartou, Fl. Amer. 61.), petiolis exappendiculatis, corollis 



calycem breviter superantibus, calycis sinuum appendiculis lanceolatis 

 ipsiusque dimidium sequantibus, placentis 2-ovulatis. 

 N. phacelioides. Bot. Mag. t. 2373. vix Bot. Reg. 



The above character is taken from the figure and description in the Bo- 

 tanical Magazine, as I have not seen the plant. It appears very nearly allied 

 to N. parv'iflora, differing chiefly by the flowers, which are twice as large as 

 the larger appendiculse of the calyx. The figure in the Botanical Register, 

 vol. ix. t. 740, appears to me to represent the N. msigms. 



4. N. AURiTA {Lindl. Bot. Reg. xix. t. 1601.), petiolis basi auriculato-dilatatis, 



calycis sinuum appendiculis elongatis, corollis calyce duplo longioribus, 

 placentis 2-ovulatis. 

 Folia dum opposita basi connata ; lobi lanceolati integerrimi divaricati vel 

 ad basin folii spectantes. Pedunculi ad apices ramorum subracemosi. 

 Corolla fere poUicem diametro. (v. s. sp.) 



From Mr. Douglas's Californian collection. 



5. N. iNsiGNis (Dougl. MSS.), petiolis exappendiculatis, corollis calyce duplo 



longioribus, placentis 10 — 12-ovulatis. 

 N. phacelioides. Bot. Reg. ix. t. 740. ? 

 Foliorum lobi utrinque 3 — 4, integerrimi vel incisi. Pedunculi folio lon-
