-Hab. Inter Restiaceas in clivo orientali montis Tabularis supra 
Kirstenbosch, alt. 2300 ped., flor. Dec. Legit H. Bolus anno 
1879. Herb. No. 4564! Zeyher 1574! 
A very curious plant, which affords an excellent instance of the 
peculiarity exhibited by many Cape plants of springing up in 
considerable numbers during certain years, while in several suc- 
ceeding years they fail to appear, and are apparently lying dor- 
mant, probably because the rainfall and requisite temperature 
have not coincided in a favourable manner. In the summer of 
1879 I saw this plant, with the allied C. Harveyana, Lindl., 
growing abundantly where I gathered it. In the summers of 
1880, 1881, 1882, 1883 I sought itin vain. It is distinguished 
from C. Harveyana by the smaller flowers and differently shaped 
labellum. The latter species seems to be rare. Lindley only 
knew it from a drawing and description by Harvey ; the drawing, 
or a drawing, appears in Lindley's herbarium ; but, by a singular 
error, Lindley himself affixed to the same sheet at a later date a 
quite different species collected by Pappe in Swartland, unknown 
to me, and, I believe, undescribed. 
Since the above was written, I have seen specimens in the Cape 
Government Herbarium collected by Pappe, which are over a foot 
high and bearing 5-7 flowers. 
* [The synonymy of this plant is rendered certain from a label in Lindley's 
herbarium with a specimen of this plant communicated by Dr. Sonder, upon 
which is written, in Sonder's handwriting, “Ceratandra bicolor, Sond., C. Hare 
veyana, Sond. in Orch. Eck. & Zeyhr., non Lindl. fide cl. Harv. in litt." —N. E.
