< Dichaea intermedia Ames & Correll hybr. nov. 
(D.squarrosa Lindley X D.trichocarpa (Sw.) Lindley) 
Folia linearia vel lineari-lanceolata, obtusa et apiculata 
usque ad acuminata vel angustata et longe apiculata. 
Sepala ovato-elliptica vel elliptico-lanceolata, obtusa vel 
subacuminata. Petala oblongo-elliptica vel elliptico- 
oblanceolata, acuta vel apiculata. Labellum carnosum, 
in circuitu late oblongo-quadratum, concavum, lobulo 
parvo angulari prope apicem utrinque instructum. Col- 
umna brevis, carnosa, ligula parva erecta subglabra vel 
ciliata antice ornata. 
This natural hybrid is vegetatively similar to J. tricho- 
carpa. However, florally, it is more or less intermediate 
between the above-mentioned species and D. squarrosa. 
Its fleshy-thickened leaves, which are 7-17 mm. long and 
2-8 mm. wide, are typically linear to linear-lanceolate 
and acuminate or tapering and long-apiculate as in D. 
trichocarpa. They are, however, sometimes obtuse and 
apiculate as in D.sqguarrosa. The lip and column (fig. 2a) 
are distinctly intermediate between those of the putative 
parents. The lip, which is 6-7 mm. long and 38-4 mm. 
wide across the middle, is fleshy and concave, broadly 
oblong-quadrate in outline (fig. 2b), with a small angu- 
lar lobule on each side near the apex. The broad, concave 
basal half of the lip resembles the condition found in D. 
trichocarpa, whereas the somewhat spreading, not strong- 
ly conduplicate, apical half resembles the typical lip of 
D. squarrosa. The column (fig. 2a) is short and fleshy, 
being 3-4 mm. long, and is provided with a small, erect, 
nearly glabrous to ciliate ligule on the ventral surface. 
The sepals, which are 8-10 mm. long and 3.2-5 mm. 
wide, are ovate-elliptic to elliptic-lanceolate and obtuse 
to subacuminate. The petals, which are 7-9 mm. long 
and 2.5-4 mm. wide, are oblong-elliptic to elliptic-oblan- 
ceolate and acute to apiculate. The flowers are described
