Miers, affinis; foliis tamen subtus minutissime papilloso - pruinosis, 
corollae tubo graciliore parte infrastaminali breviore parte suprastaminali

flexuosus, 1-1°5 em. longus. Inflorescentiae axillares, racemoso-cymosae, 
cum pedunculo gracili flexuoso 8-12 cm. longae, floribus superne approxi- 
matis, nutantibus; bracteae ovatae, tenues; pedicelli 1-1-5 cm. longi. 
Sepala ovata, obtusa, superne membranacea, 4—5 mm. longa, intus glandula

staminum insertionem situm sulphurea, 4 cm. longa; tubus basi angustus, 
ad staminum insertionem constrictus, abhince in flore plane aperto gradatim

Dr. Stapf finds that the South American Hchitideae, more 
particularly those referred at one time or another to Eehites 
and the more nearly allied genera, are in a state of such 
confusion as to stand in urgent need of revision. The most’ 
recent attempt to elucidate the affinities of the species in 
this group was that of Miers, whose memoir, “A pocynaceae of 
South America,” based on somewhat scanty material, is not
