Mexico: Chiapas, at 4000-6000 feet altitude, “‘moist bank of trail 
above Liquidambar,’’ flowers white, November 9, 1945, A. J. Sharp 
45977 (Tyrer in Herb. Ames No. 65446). 
Pleurothallis Broadwayi 4 mes Orch. 2 (1908) 267. 
Pleurothallis guadalupensis Cogniaux in Urban Symb. 
Antill. 6 (1909) 432. 
Pleurothallis Williamsti Ames Orch. 7 (1922) 120. 
Pleurothallisnana A. & 8. in Sched. Orch. 8 (1925) 29. 
The above synonymy, except for Pleurothallis nana, 
has already been published (C.Schweinfurth in Bot. Mus. 
Leafl. Harvard Univ. 8 (1940) 41). 
At the time when Pleurothallis nana was erected, it 
was thought to be distinct from the concepts referable 
to P. Broadwayt. It seemed to have longer and more 
branched stems than the other species of this group. It 
also appeared to be separable by reason of its longer pedi- 
cels, ‘‘snow white’’ rather than yellow or greenish yellow 
flowers and especially because of its narrower and more 
acuminate sepals. 
A recently acquired Mexican collection (Nagel & 
Juan G. 6447), although it appears to be inseparable 
vegetatively from the Costa Rican P. nana, has long 
pedicels and sepals intermediate in form between those 
of typical P. Broadwayi and P. nana. It is further noted 
as having pale yellow-green flowers, as in P. Broadway. 
A Costa Rican collection (Austin Smith H541) also has 
pedicels of a length intermediate between the two con- 
cepts and flowers noted as pale lemon yellow as in P. 
Broadway; but it has sepals of quite the form of P. nana. 
Therefore, in view of the great variability naturally to 
be expected of a wide ranging plant, it seems advisable 
to regard P. Broadwayi as representing one polymorphic 
species. It occurs in Mexico (Oaxaca), Honduras, Costa 
Rica (type of P. nana), Panama (type of P. Williamsii),
