Before seeing any Bet piliferous form I ag: expressed the opinion 
to Rev. W. W. Watts, of Sydney, N.S.W., that C. bicolor was properly 
viewed as a hairless form of what should be, normally, a piliferous species. 
Shortly afterwards Mr. Watts sent me a plant as “ C. duvalianus Watts 
n. sp.,” which had been cas named C. clavatus R. Br. by Brotherus. 
The basal areolation is, however, quite different from that of C. clavatus 
(cf. my note in Journ. Linn. Soc. (Bot.), xl, 438), and I do not think there 
is any doubt that this plant is a tone form of C. bicolor, and in fact 
many of the leaves have the abru spate — of the ordinary forms. 
I had proposed to call this pliers form “ r. duvalianus,” but I find on 
examination of the type o er’s C. er eto that it is certainly the 
same thing, and [ have sieretais Seats the name for the variety. From 
a morphological point of view the piliferous ued should no doubt be 
considered the typical form, the muticous the varietal; but the far greater 
prevalence of the latter, apart from priority of description, warrant its 
retention as the type.

C. Kirkii is systematically nearly allied to C. ase but is a quite well- 
marked species, and fairly easily recognized ; and is one of the most distinct 
of the genus. The leaves are less tapering, more oe and cucullate
