68 THE ORCHID REVIEW. [May-June 1920. 
feet by the Aerenometer), on the banks of the Caldera River, where we 
made our headquarters. From there, riding or walking the hills and valleys 
in all directions, we covered the territory selected for exploration. I 
suspect that Lino is the spot Warscewicz made his headquarters, as it is 
the only place on the Caldera river at 4000 feet elevation. Not many 
plants were in flower while I was there, many having flowered out, and 
many were in flower spike, but not fully developed. 
Having before me the list from the Biologia Centrali-A mericana, which 
you kindly sent me, I can say that Warscewicz did not get one-third of the 
Orchid flora of Chiriqui. A peculiar condition seems to maintain there— 
every hill, valley or river bank seems to have its own series of plants, 
distinct from the others, though, of course, some were found universally. 
I procured many handsome plants which I did not possess before—I cannot 
yet say how many, but estimate them at some 50 or more—and I believe 
that I have now procured most of these listed by Warscewicz, and many 
more. I brought back with me eleven crates ot plants, and have been very 
busy staging them. From these you will ultimately receive botanical 
specimens as they come into flower.—C. W. PowELt, Balboa, Canal Zone, 
Panama, March, 1920. 
Six interesting views are enclosed by Mr. Powell, Bouquette Village, at 
4000 feet elevation, pleasantly situated in the Bouquette Valley, through 
which the Caldera River runs; a native hut with eight residents; a view 
overlooking Bouquette Valley from Lino Rock, a bare pinnacle of rock, on 
top of one of the hills; looking towards Chiriqui from Lino; Narajos 
Valley—this and the last showing the Log Slide, 4500 feet, and Chiriqui 
Volcano in the distance; and Narajos and Lino from Log Slide, with 
scattered farm houses. They give a graphic idea of the locality, and show 
the Chiriqui Volcano, estimated at 12,000 feet altitude, as the highest peak 
of a long mountain range. 
The list of Panama Orchids mentioned above contains 104 species. 
It was based chiefiy on Reichenbach’s earlier Orchidez Warscewicziane, 
the exclusion of a few non-Panama species being about balanced by 
subsequent additions. From an introductory note we learn that 
*Orchidez are plentiful in the vicinity of the rivers, where the trees are 
literally loaded with them. The vanilla climbs in abundance up the stems 
of young trees, and often increases so much in weight as to cause the 
downfall of its supporters.” 
As to Warscewicz’s localities, we should judge that he collected up to 
near the summit of Chiriqui, for altitudes are cited from 1000 right up to 
10,000 feet, though few other details are given. When the plants 
mentioned by Mr. Powell have been worked up we anticipate some 
interesting additions to the flora.
