Sent from Sierra Nevada, Santa Martha, by our collector, Mr. 
Purdie, to the Royal Gardens of Kew. It has some characters 
in common with JZ. aromatica, Hook. Exot. Fl. t. 219, and with 
M. cruenta, Lindl. Bot. Reg., 1842, t. 13.; from the former it may 
be known by the larger size in every part of the plant, by the 
Scentless flowers and different shape of the lip; from the latter 
by its smaller differently coloured blossoms, by the very dissimilar 
labellum and the absence of the crimson blotch on its under side. 
Derscr. Pseudo-bulbs large, ovate, compressed, in age slightly 
wrinkled, bearing from the summit several large, oblong, mem- 
branaceous, waved, acute, Jeaves. Peduncles generally two, one on 
each side of a pseudo-bulb, much shorter than the leaves, partially 
sheathed with distant inflated scales, single-flowered. Flowers 
rather large, paleish yellow. Sepals ovato-oblong, spreading, . 
little waved, united at the base so as to form a short blunt spur. 
Petals shorter and broader than the sepals. Zip the length of the — 
petals, oblong, concave, three-lobed, spotted on the disc and with
