ORCHIDACEiE 



multiflorus, bracteis membranaceis, ovato-lanceolatis, setaceo- 

 acuminatis. Flores purpureo-fusci etflavo-variegati. Pedicelligra- 

 ciles. Sepala lateralia ovato-lanceolata, acuta, leviter undulata. 

 Sepalum dorsale simile. Petala elliptico-ovata apice rotundata et 

 minute apiculata. Labellum trilobatum, anguste longeque un- 

 guiculatum; lobi laterales erecti late falcati, ad apicem rotundati; 

 lobus medius prope basim quadratus, superne dilatatus, late retu- 

 sus ; discus inter lobos laterales crista oblonga carnosa quadrilo- 

 bata ornatus. Columna clavata, crassa, exalata. 



Roots rather coarse, whitish in dried specimens, smooth. Pseu- 

 dobulbs erect, 5-8 cm. long, ±1.5 cm. in diameter below the mid- 

 dle, in dried specimens much wrinkled and with yellowish brown 

 annulae at the five to eight points at which the leaves were borne, 

 the fibrous remains of the leaves persistent. Leaves ±1.5 dm. long, 

 ±5 mm. wide at flowering time, ±4.5 dm. long, ±1.5 cm. wide 

 when mature, erect, coriaceous, many nerved, linear, acute, apicu- 

 late, soon surpassed by the elongated scape with which they arise 

 from the base of a mature and defoliated pseudobulb, middle 

 nerve prominent beneath. Scape ±4 dm. tall, erect, with a few 

 scattered bracts below the raceme, the bracts ample, the lower- 

 most one sheathing and obliquely truncate, acute. Raceme ±1.5 

 dm. (sometimes exceeding 3 dm.) in length, for the most part 

 simple sometimes branching below, many flowered. Bracts of the 

 raceme about 1.5 cm. long, membranaceous, ovate-lanceolate, 

 acute, a little shorter than the pedicellate ovary. Pedicels slender 

 with the ovary up to 2 cm. long. Flowers about 2 cm. across, some- 

 times 2.5 cm. across between the tips of the lateral sepals, brown- 

 ish-purple with yellow spots and blotches. Sepals and petals 

 spreading. Lateral sepals 9-12 mm. long, up to 6 mm. wide, 

 ovate-lanceolate, acute, margins undulate. Petals 8-11 mm. long, 



±7 mm. wide, elliptic-ovate, very slightly clawed, apparently little
