Tins plaut would almost form the type of a uew subsection 

 of the geiiUH, differing, as it does, from the rest of tlie genus 

 in the entire absence of any pubescence, and the erect lanceolate 

 leaf; the rest of tlie species, as far as known to me, having one 

 or two ovate or orbicular radical leaves lying flat upon the ground. 

 The flowers are rather larger t'^au in most species, densely packed 

 in a sccund raceme. According to a drawing made hj Deans 



Cowan, they are greenisli-yellow in colour. The lip is three-lobed, 

 the lateral lobes shorter and narrower than the lanceate triangular 

 middle one. There are, as in most species of the genus, two 

 small oval granular bodies on either side of the column, hotno- 

 logons to the lateral lobes, or auricles, occurring in some of 

 the Ilahenarice, It seems likely that they are rudiments of the 

 two lost stamens.

This is certainly the largest Satyrium known to me. Tlte 

 great size, long curved spurs, and narrow petals make it an easily 

 distinguishable plant. Other Satyria obtained by Dr. Foi 

 were: — S. irinerve^ Lindl., common in damp places, Andrango- 

 loaka, Ambatovory, &c. ; and S. amoenum, Lindl., Ambatovory, 

 not hitherto recorded from Madagascar.
