P. cixctum (Baker). Caule herbaceo ramoso breviter griseo-canescente, 
bracteis parvis ovatis, foliis rotundato-reniformibus distincte zonatis 
ad tertiam vel dimidiam latitudinis palmatisectis, utrinque tenuiter 
griseo-pubescentibus, umbellis 2—3-floris, petalis parvis equalibus 
rubro maculatis sepalis non excedentibus. 
A native of Cape Colony, imported in a living state, like the 
three last, by Mr. Cooper. 
General habit as in the three last, but the whole plant ona 
smaller scale. The stems slender, harsh to the touch, the hairs 
throughout short and subadpressed. Bracts ovate, two to two 
and a half lines long by about half as broad. Fully-developed 
leaves one and a half inch to two inches broad, firm in texture, 
the pubescence thin and adpressed like that of the stem, the 
divisions reaching from a third to half-way down, the zone of 
brown very prominent and quite permanent, even in dried speci- 
mens. lowers never more than two or three in an umbel. The 
pedicels, including the calyx-spur, six to eight lines long. Sepals 
four lines deep, linear-acuminate, thinly canescent on the back. 
Petals subequal, four lines long by under a line broad, just 
equalling the sepals, the two upper ones erect, close to each other 
three-quarters of the way up, pure white with a distinct scarlet 
spot in the middle and sometimes with a few dots above and 
below it. Beak with carpels an inch long.

A very pretty-foliaged plant, particularly in the state before 
flowering, when the bright rich green leaves, with black horseshoe 
zones, cover the surface of the pot. The flowers are small, but 
lively in appearance and produced freely. This is another species 
of Mr. 'T’. Cooper’s collecting in South Africa, and I received the 
plant from him. Requires the same treatment and soil as the 
foregoing species.--W. W. S.
