OPHRYDES. 365 
A beautiful species, with deep yellow flowers twice as large as those of 
any other. 
2. Evota. Stigmatis brachia dilatata, conniventia, galee speciem formantia 
(Calota, Harvey, MSS.). 
6. CeraTanpra Harveyana. 
C. foliis linearibus acuminatis involutis, spicà pauciflorà laxiusculà, bracteis 
ovatis acutis convexis, petalis cuneatis rotundatis unguiculatis margine 
crispis, labello sagittato appendice rhomboideo carnoso integro.

I only know this curious plant from a drawing and description by Mr. 
Harvey, in the possession of Sir W. Hooker. It is represented as growing 
about six inches high, with green sepals, and all the other parts of the 
flower yellow. The dilatation of what I presume to be either the arms of 
the stigma or the rostellum, is very remarkable, and led Mr. Harvey to 
consider it distinct from Ceratandra and Pterygodium, naming it Calota 
capensis ; but it is in all other circumstances, so far as I can judge from 
the drawing, as well as in habit, so entirely a Ceratandra that I do not 
think it expedient to separate it. It forms however a good section of this 
genus, for which the name Calota might have been retained if we had not 
already a Calotis, and for which that of Evota, a word with the same 
meaning, has been substituted. 
CCVII. OMMATODIUM. 
Perianthium ringens. Sepalum supremum et petala inequaliter lobata 
apice fornicata in galeam agglutinata ; lateralia patula libera. Label- 
lum hastatum, sessile, columne adnatum, appendice membranaceo tu- 
buloso auctum. Columna membranacea, truncata. Anthera erecta, 
loculis distantibus, subparallelis, basi truncatis ; glandulis nudis. Stigma 
horizontale, brachiis incurvis. Herba radicibus testiculatis, Ace- 
ratis habitu. 
This genus is essentially different from Pterygodium in its anther being 
perfectly erect, and very much like that of a Platanthera. Its name is 
taken from the eye-like spots on the labellum.
