Rio by the discovery of a wonderfully beautiful orchid growing on 
the trunk of the pond apple (Anona palustris) in a little marsh. 
The orchid was in full bloom, its flowers of a bright magenta, 
forming clusters a foot or more long, the individual blossoms 
more than an inch across. Only four individual plants could be 
found after a long search and these were all on one tree. he 
plant seems to be in the genus Broughtonia ad is apparently 
undescribed 
The second schooner expedition occupied the period from March 
8 to March 16, sailing west from Coloma as far as the Bay of 
Corrientes, near the western end of the island, touching, both 
going and coming, at the Laguna de Cortes, near Cape Francis, but 
at no other intermediate points, because from just west of Cape 
Francis to Cape Corrientes the coast is an unbroken vertical es- 
carpment, with no harbors and no way of landing upon it safely, 
except when the wind blows from the north or northwest, which is 
unusual. Along Corrientes Bay, after we had rounded the Cape, 
after sailing against the strong current for some time, we found the 
rock wall setting back from the coast and landed at four different 
points and were thus able to obtain a good view of the vegetation 
and to make quite extensive collections. The flora was quite 
varied, containing many species common to the coastal woodlands 
and thickets of other parts of Cuba, but also a number of others 
with which we are unacquainted and which = form interesting 
objects for study. The stout ‘palma cana,” a palm of the genus 
Sabal, related to the palmetto of Florida and the Bahamas, 
occurs here in large groves in places almost to the exclusion of 
other trees, so striking i in appearance from the sea that one of

thatch palm, ‘‘palma lana” (Thrinax sp.) so-called from the vel- 
vety coating of the inner surface of its leaf sheaths, was exceed- 
ingly abundant, its slender trunks attaining a height of 4o to 
50 feet, and with it the “ sae blanca”’ (Copernicia sp.) attained 
almost equal height. Two cactuses were abundant on the rocks, 
one an upright bushy pees the other a trailing and climbing 
Selenicereus, both night-flowering species, but not in bloom at
