P. LEHMANNI, Regol. — A plant collected by Herr Consul Lchmann in the 

 Western Cordilleras of Colombia at an altitude of 7,000 feet. It is allied 

 to P. fragrans, of which indeed it may possibly prove to be only a variety. 

 Pseudobulbs ancipitous ovate monophyllous ; flowers white, sepals and petals 

 narrow linear-lanceolate; lip sub-quadrate with a bilobed apex, and a round 

 orange stain at the base. — U.S. of Colombia. 



Fig.— Gartenflora, 1890, t. 1276, f. 2. 



Stn. — TriclwpUia Lehmanni. 



P. NOBILIS, Rchb. f. — This beautiful species is worthy of a place in every 

 collection, and indeed should be grown in quantity by every one, so attractive 



and useful are its fragrant 

 flowers. The pseudobulbs arc 

 elongate oblong compressed, 

 clustered, monophyllous, the 

 leaves being broadly oblong 

 acute ; the flower scapes are 

 radical, erect, bearing four or 

 five deflexed blossoms, which are 

 larger than those of P. fragrans, 

 and are also sweet-scented; the 

 white sepals and petals are linear- 

 lanceolate undulated, and the 

 lip is sub-quadrate, constricted 

 near the top so as to appear 

 obsoletely three-lobed, the upper 

 lobes rounded and meeting over 

 the throat, the front one much 

 larger, retuse. If inch bread, 

 pure snow white, having en 

 each side of the throat an 

 orange- coloured blotch, the two 

 blotches meeting to form a 

 central eye-like spot. — TJ. S. of 

 Colombia; Peni.
