 Tohnie. Dr Gairdner.^Tlus western plant seems to me scarcely to differ from C. coccinea, except in 

 being more \illous, rather than hispid. Bracteas sometimes full yellow, as is the case with the preceding-. 

 Mr Bentham remarks (ms.) : " Flowers of C. pallida ; foliage of C. coccinea. Nearly allied to this is the 

 C. parvijlora. Bong. Veg, de Sitch. p. 40." but of which no specific character is given ; there is however the 

 observation, '' valde affinis C coccinecs, a qua autem tam habitu quam floribus duplo minoribus differt." 

 The author has kindly sent me specimens, but the flowers do not appear to be fully developed. 



3. C. septentrionalis (Lindl.) ; pilosa v. rarius glabrata, foliis plerisque incisis calycibus 

 utrinque prassertim infra fissis segmentis apice bifidis laciniis ovatis corollam aequantibus.

 Gastjourney).— The species of this genus are liable to much variation, and their essential characters diflicult to 

 be determined ; hence there is much confusion among authors. Cbamisso and Schlechtendal consider the 

 C. septentrionalis of Lindley, and the Europaean/?fl//zVa (Lindley*s Sibirica) to be identical. I will not at- 

 tempt to decide the point from dried specimens, where the flowers cannot satisfactorily be examined, but con- 

 tent myself with Mr Bentham's definitions, made from our own specimens.
