and oblong- or elliptic-lanceolate) up to 19.5 em. long 
and 4.3 cm. wide, and racemes up to about 9 em. long. 
Klleanthus conchochilus has somewhat smaller leaves 
(up to 11 em. long and 2 cm. wide), a raceme up to 6 
em. long and floral segments (shown by analyses of the 
type as well as by the description) which are almost iden- 
tical with those of 7. Weberbauerianus. 
Apparently the only noteworthy difference between 
the concepts is one of flower-color, 17. Weberbauerianus 
being purple with white and brown lip and 2. conchochilus 
said to be yellow. 
It thus appears that these three concepts are specifi- 
rally identical.

Elleanthus discolor Reichenbach filius in Walpers 
Ann. 6 (1862-3) 480-1. 
In his original description of the Peruvian J/velyna 
discolor, Reichenbach cites as the more obvious differ- 
ences from the related 1’. hymenophora the violet under 
side of the foliage, the erect inflorescence, the denticulate 
(not entire) keels on the lateral sepals, the broader more 
denticulate lip and the erect triangular acute (not retuse) 
rostellum. 
A specimen of the type number of Zvelyna discolor 
in our herbarium does not show any noticeable difference 
in coloration between the leaf surfaces, and the floral 
parts appear to match those of //.hymenophora, with the 
keels on the lateral sepals entire or nearly so. Moreover,
