 dunculi inferiores oppositifolii, superiores in racemo laxo unilaterali simplici dispositi. 



1. E. membranacea (Benth.); glaberrima, petiolis exappendiculatis, foliis pinnatifidis 

 segmentis integerrimis, calycibus vix auctis. Benth. I. c. p. 274. 



Mr Bentham describes the lobes of the leaves as broadly lanceolate, but in all our specimens they are 

 broadly linear and obtuse. 



2. E. chrysanthemifolia (Benth.); hispido-scabra, petiolis basi auriculato-dilatatis, foliis 

 subbipinnatifidis, lobis inciso-dentatis obtusis, calycibus fructiferis parum auctis. Benth.

1. N. parviflora (Dougl.~) ; foliis pinnatifidis, lobis paucis latis subdentatis, calycis

2. N. pedunculata (Dougl.) ; foliis pinnatifidis, lobis paucis latis subintegerrimis, calycis 

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

 Benth. I. c. 



In the Columbia plant, the leaves are almost as broad as in JV. parviflora ; in that from California they 

 are narrower, the lobes shorter, more distant from each other, and quite entire. The calycine appendages 

 are so very minute as not to be detected without careful examination. 



3. N. aurita (Lindl.) ; petiolis basi auriculato-dilatatis, calycis sinuum appendiculis 

 elongatis, corollis calyce duplo longioribus, placentis 2-ovulatis. Benth. I. c. 



4. N. Menziesii (Hook, et Am.) ; petiolis exappendiculatis, foliis pinnatifidis, segmentis 

 approximatis ovatis integerrimis vel bi-tridentato-lobatis, pedunculis oppositifoliis elonga- 

 tis, corollae (coerulea; parce nigro-punctatae) rotatae fundo pilosse laciniis obovatis calyce 

 subduplo longioribus, placentis sub-10-ovulatis. — a. corollaa calycem vix duplo superante. 

 — N. Menziesii. Hook, et Arn. supra, p. 152. Benth. I. c. p. 276.-/3. corolla calycem plus 

 duplo superante — N. insignis. Dougl. ms. Benth. 1. c. p. 276 (excl. syn.). Hort. Soc. 

 Trans. N. Ser. 1. p. 643. Lindl. in Bot. Reg. t. 1713. Hook, in Bot. Mag. t. 3485. 



Our first variety has the flowers considerably smaller than P., as small indeed as in IV. atomaria, Fisch. et 

 Meyer, Ind. Sem. Hort. Petr. 2. p. 43 (Lindl. in Bot. Reg. t. 1940), but the flowers of the latter are white, 

 and strongly marked with numerous dull lead-blue specks, and therein seems to lie the principal difference 

 between the two species. Dr Lindley states that in JV. atomaria the peduncles are hairy, and in N. insignis 

 glabrous ; but in our specimens of the latter, the peduncles vary from almost glabrous to perfectly hairy. 

 We fear that the two species ought to be united. JV. phacelioides, of the Bot. Reg. t. 740, appears to us 

 a large cultivated form of the true N. phacelioides of Barton.
