All but C. atteiitiata^ are in the herbarium of the Natural 

 History Museum at South Kensington. This species was seen 

 in Hb. Hooker, by Dr. Boott, and by him referred to C. rupestris 

 All. - 



C. affinis^ R. Br. Frankl. Narr. App. y6^, was referred by 

 Dr. ]5oott to C, ohttisatay Lilj. Three sheets were placed to- 

 gether in the museum, the specimens all collected on the same 

 expedition, of which two sheets are not labelled, but are evi- 

 dently C. ohttisata^ ^X'&iow^x too young for positive determina- 

 tion. The third sheet is Brown's type of C. affinis, and is Ko- 

 bresia scirpina^ Linn.

C. podocarpa^ Frankl. Narr. App. ed. ii. 36, has been entirely 

 misunderstood. It is apparently a form of C, atrofttsca, Schk. 

 {C. 7istulata, Wahl.). From most specimens of C. atrofusca it 

 differs more or less in the entire orifice of its perigynium, which 

 is not at all puncticulate, somewhat narrower spikes, and broader 

 leaves. But C, atrofusca Is a variable species, and in the absence 

 of more and better material, I throw the two to<:[ether for the 



present The plant which has passed for C, podocarpa R. Br. 

 (Boott. 111. 197 ; Bailey, Proc. Amer. Acad. Arts and Sci. xxiL 

 94), is C. macrochcBta^ Meyer. 



The following species are properly understood by American 

 botanists : 



C, aristata, Frankl. N*irr. App. 764 : C. trichocarpa var. aris- 



tata^ Bailey. 

 C, Richardsoni^ Frankl. Narr. App. j6'^. 

 C, viisandra^ Suppl. Parry's Voy. 283. 

 C. conciiina^ Frankl, Narr. App. ^62^^ 

 C^ cojnpacta^ Ross's Voy. App. cxliii. 

 C. media, Frankl. Narr. App. 763 : C. alpina, Swtz. 

 C. nmtica, Frankl. Narr. App. 'j6i\ C. anrca, Nutt.
