Wahl. Car. no. 73. 



This is the C. folliculata, L. (3. xanthophysa in Mnh. 

 We have his authority that it is the above named species of 

 Wahl., and perhaps the C. intumescens ofRudge. Wahl. con- 

 sidered the two species to be distinct, and there is much 

 reason for adopting his opinion. The Fig. of C. folliculata 

 in Schk. bears no resemblance to this species. 



C. folliculata. is readily distinguished by its one to three 

 pistillate spikes, aggregated, scarcely peduncled, supported by 

 long leafy bracts ; its close-set oval-conic or ovate-acuminate, 

 much inflated fruit, much longer than the ovate-cuspidate 

 scale. The whole plant is deep green. 



C. xanthophysa has two to four pistillate spikes, often on 

 very long peduncles and very distant, staminate at the apex, 

 inclosed in sheaths, often long^ and terminating in long leafy 

 bracts ; oblon^-conic, inflated fruit, close-set, horizontal, and 

 a little longer than the ovate-acuminate, or ovate-lanceolate 

 scale. The whole plant is pale yellow. 



Both species are commonly described as having spikes 

 about six-flowered. This is rather an indefinite character, 

 and many specimens differ considerably from this number. 

 C. xanthophysa, especially, often has several more. But, 

 while both species have one staminate spike, they differ ve- 

 ry much in the pistillate spikes, in their sheaths, in the 

 shape of their fruit, and in the shape and length of their 

 scales. The whole appearance of the two plants is very 

 dissimilar. They differ much more than several of the 

 species which are considered as distinct. 



To prevent error, it may be proper to remark, that de- 

 scriptions and figures of C. folliculata and C. intumescens, 

 are given by Rudge in the Lin. Trans., and that the char- 

 acters of C. intumescens in Rees' Cyc , which seem to have 

 been taken from the Lin. Trans., prove that C. intumescens, 

 Rudge, and C. xanthophysa, Wahl. cannot be the same 

 plant. The popular characters of C. intumescens are there 

 g'ven, pistillate spikes loosely imbricated and on short pedun- 

 cles, with scales oblong-ovate, acute, and half the length of 

 the erect, ohlong-ovate, much inflated, long and acute beaked 

 fruit. The C. intumescens may be a var. of C folliculata 

 perhaps, but not of C. xanthophysa. Neither can the C. 

 intumescens be the same with C. lurida, Wahl., as stated in 

 Rees' Cyc, which is more probably the C. lupulina, Muh,
