DOUBTFUL SPECIES 



15. S. OVALIS, Lindl., Orch. PI. 466 (1840): "S. glaberrima, 

 foliis radicalibus et caulinis lineari-ensiformibus acutis, spica ovali 

 densa multiflora, bracteis ovatis acutis, sepalis petalisque lineari- 

 bus obtusis, labello oblongo membranaceo apice recurvo crispo; 

 callis elongatis falcatis sagittam referentibus. 



" Hab. in Texas, Drummond. {exam. s. sp. in herh. Hooker.) 

 " A plant from 6 to 9 inches high. Spike like that of S. odo- 

 rata, but much smaller, and the flowers not larger than those 

 of S. gracilis. A very distinct and apparently rare plant ; for it 

 seems that Mr Drummond found only three specimens, all pre- 

 served in Hooker's Herbarium."
