"original"; the other is labeled "C. ienera D. Saddle Mt. [Williams- 

 town, Massaciiu.sett.s], June 20" and the usual word "original" added. 

 On other labels of similar plants sent to him by various collectors,— 

 Sartwell, Macoun, and others — Dewey has written "yes," etc. These 

 |)lants are mostly quite identical with the "original" specimens and 

 the species is clearly the plant which was understood as C. tenera by 

 Carey, Francis Boott, and others who had material from Dewey. This 

 plant as already indicated is identified with the Willdenovian C. 

 straminea} Thus since the name C. ienera Dewey can no longer be 

 applied to the larger plant to which it has recently been transferred, 

 and the name apcHa applied by Boott to the plant, as a variety of C. 

 straminea, is already usetl in the genus, it becomes necessary to desig- 

 nate the species by some other name; and on account of the usually 

 elongate moniliform inflorescence this coastal plant is here called C. 

 Iionnatliodes, of which the following varieties are noteworthy. . 



C. HORMATHODEs, var. invisa (W. Boott), n. comb. C. straminea, 

 var. invisa W. Boott, Bot. Gaz. ix. 8(5 (1S84). C. tenera, var. invisa

C. rosea Schkuhr and its varieties, radiata Dewey, and minor Boott, 

 have their perigynia with minutely serrulate margins, the scales blunt, 

 and the spikes mostly remote. C. retroflexa and its var. texensis, on 

 the other hand, have the perigynia with smooth margins, the scales 

 acuminate, and the spikes mostly approximate. In no character do 

 they .seem to diflfer excej)t in the outline of the j)erigynia, tho.se of C. 

 retroflexa being broadly ovoid, of var. texensis lance-ovoid to lance- 

 subulate. Though occasional transitional plants occur the two seem 

 to be fairly marked extremes, the variety standing in the same relation 

 to the species as C. sfelhdata, var. angnstata (^arey, C. inferior, var. 

 Josseli/nii Fernald, C. r/ra)iularis, var. Haleana (Olney) Porter, C. 

 vesiraria, var. Raeana (Boott) Fernald, &c. to the broad-fruited tyj^es 

 of their respective species. The occurrence of C. retroflexa, var. 

 texensis throughout the southern range of the s|>ecies — from Kentuck\'
