scribed his 8. parviflora, he also cited specimens from 
Colombia. These Colombian specimens apparently rep- 
resent Kraenzlin’s concept of 8. AKalbreyert. My exami- 
nation of these materials confirms my belief in their 
identity with S. D’Orbignyana, of which I have also 
studied the type in the Vienna Herbarium. 
Spiranthes coccinea Garay nom. nov. 
Basionym: Stenorhynchus cernuus Lindl. in Ann. Mag. 
Nat. Hist. 15: 386, 1845, not Spiranthes 
cernua (L.) L.C. Rich. 
This striking and locally uncommon species 1s known 
from Colombia and Ecuador. It is closely related to the 
Peruvian Spiranthes corymbosa Kral.

em. latis; inflorescentia erecta, paululo arcuata, laxiflora, 
usque ad 30 cm. longa; bracteis lineari-lanceolatis, acu-

Without proper locality and collector. Typr in Herbarium of the 
Natural History Museum, Vienna (Reichenbach 37739) (W). 
This new species, probably of Andean origin, is easily 
distinguished from other members of the genus by its 
serrate petals.
