transversely oblong or oval-oblong and retuse-apiculate 
rather than ‘‘suborbicular.’’ The dates of collection ex- 
tend from June 16 to August 21, 1922. 
Spiranthes maculata C. Schweinfurth comb. nov. 
Pelexia maculata Rolfe in Kew Bull. (1893) 7—Sum- 
merhayes in Bot. Mag. 158 (1985) t. 9418. 
In accordance with our plan of simplification, the genus 
Pelexia is referred to Spiranthes and a new combination 
is thus necessitated. 
Although the habitat was cited as ‘‘not recorded”’ in 
the original diagnosis and was later cited by Summer- 
hayes as questionably from Venezuela, we have seen a 
definitely localized collection from the Herbarium of the 
Field Museum. The data are as follows: 
Peru: La Merced, at about 600 meters altitude, edge of mountain 
stream, leaves mottled with lighter green, flowers “‘white tipt, slightly 
reddish without’’, August 10-24, 1923, J. Francis Macbride 5526. 
This Peruvian collection differs from the type in having 
somewhat larger leaves which are up to about 18 cm. long 
and 8.5 em. wide. 
Spiranthes Rimbachii (Sch/tr.) C. Schweinfurth 
comb. nov. 
Cyclopogon Rimbachii Schlechter in Fedde Repert. 
Beihefte 8 (1921) 166. 
The transfer of this concept to the genus Spiranthes 
requires a new combination. 
A Peruvian collection of this species has been recently 
examined. It differs from the Ecuadorian type in the 
following particulars: one plant reaches about 6 dm. in 
height (in contrast to a maximum height of 5 dm.), one 
plant bears six basal leaves and another specimen bears 
eight cauline sheaths (in contrast to a maximum of four). 
The lip is slightly broader than that of the type and is 
about 7 mm. wide.
