which this species was based, it seems advisable to accept 
Lindley’s interpretation of Z’.paniculatum, particularly 
in view of the fact that he had seen a Pavon plant from 
Peru, in Herb. Lambert, collected in Huayaquil: the 
type was collected in Muna. Lindley described the plant 
as having oblong-lanceolate acuminate leaves, a many- 
flowered crowded panicle, oblong sepals externally vari- 
cose on the veins, filiform petals, and a 4-lobed labellum 
of which the forward lobes are divaricate and linear. In 
Foha Orchidacea Epidendrum (1858) 56, Lindley cites 
as representative of EH. paniculatum, among other collec- 
tions, Funck & Schlim 1448 and Schlim 68. We have 
photographs of these sheets which are characteristic of 
the conception of J7. paniculatum widely prevalent to- 
day. This form has been reported from Martinique, Co- 
lombia, Venezuela, Ecuador, Boliviaand Peruand belongs 
to one of the two basic groups into which the alliance has 
been previously divided. The other group is represented 
by Lpidendrum floribundum HBK. of which the type 
collection is from Brazil and represents a species which 
is distributed through Mexico and Central America ex- 
tending southward to Brazil, Ecuador and Peru in South 
America. It is described and illustrated (upper portion 
only) by Humboldt, Bonpland & Kunth (Nov. Gen. et 
Sp. Pl. 1 (1816) 358, t. 86) as a plant about a foot high 
with elliptic-lanceolate acuminate leaves and with a rath- 
er open panicle, the branches subtended by lanceolate 
acuminate bracts which are up to 8.8 cm. long. The flow- 
ers are about 1.5 em. across, with lanceolate acuminate 
and reflexed sepals about 1 em. long. The petals are lin- 
ear-spatulate and slightly longer; the lip is 4-lobed with 
an elongate tubular claw which is adnate to the column. 
The lateral lobes of the lip are subrotund-quadrate and 
the mid-lobe is transversely linear-oblong with divaricate 
lobules, separated from the lateral lobes by a much-nar-
