Rh, chamaetortum, Balf, {. et Ward). They agree in having a 
reddened calyx without marginal hairs but fringed with scales. 
The reddening of the calyx occurs also in Rh. chamaetortum 
where it is associated with a slightly ciliate margin but is 
not common in the Cephalanthum series. They agree also in 
having a style which is longer—only slightly—than the ovary 
and which does not show the marked clavate enlargement 
upwards to the stigma as in other species of the Cephalan- 
thum series. In the general run of their other characters the 
species are well within the Cephalanthum limit, and they 
differ from one another in a way which marks their distinctness. 
The following are easily observed points by which Rh. nwaiense 
is diagnosed from its ally: leaves smaller, of a maximum 
length of 2 cm,—I should interpolate here that the material 
of neither of the species is abundant and of Rh. nwaiense in 
particular is rather scanty ; the leaves may therefore be larger 
than the specimens available show—scale-leaves of the vegetative 
buds narrow-pointed and persistent, fertile bracts much smaller 
and narrower, bracteoles shorter than the calyx, pedicels lepidote, 
and corolla lobes outside sparingly lepidote. 
Rh. nwatense may be taken as the southern form of what 
appears in the north as Rh. gymnomiscum.
