10. PONERA ROSEA Rchb. fll. in Bonpl. II. 22. Huc : Scaphyglotlis rosea Hook. Ic. 

 Plant. IV. (1841). ib. 313. 



Pseudobulbis elongafo-cylindraceis sulcatis proliferis, foliis Hnearibus 

 obtusis, floribus geminatis , labello obovalo, spathulato, apice recurvo 

 trilobo lobo medio acuminato. Hab. Demerara C. S. Parker Esq. 



Near S. vfolacea Lindl. bul as we examined this in a lliving state we pronounce it 

 disiinct. The flowers of this are of a much paler hue , the sepals and petals of an 

 uniform rose colour: but Ihe chief characteristical lies in the labelium, which is here 

 attenuated below into a long narrow claw , while the upper half is curved down, 

 ihe apex 3Iobed, ihe middle coming to a ralher sharp point. The habit of this gcnus 

 is peculiar in its proliferous pseudobulbs : but the struclure of ihe flowers seem to 

 me scarcely diirering from that of Maxillaria.
