WyAsveEva LLIA PACHYANTHA was first described by Professor Reichenbach in 
Iss4, from specimens sent to him by Messrs. Carder and Shuttleworth, in whose 
collection it flowered for the first time in cultivation. Whether the original discoverer 
of this species was Mr. Cross or Consul Lehmann seems uncertain, for Reichenbach 
states that he had specimens “a long while ago,” collected by Mr. Cross; adding, 
“Lehmann also wrote to me about it long ago.” 
Z In the British Museum of Natural History there are dried specimens collected by 
Mr. Lehmann in 1881 on the western slopes of the Central Cordilleras of Popayan, at an 
elevation of 3,000—3,500 metres (9,500 to 11,375 feet), and others found by him in 1882, 
growing upon trees in damp mountain woods on the western slopes of the Paramo de 
Moras, at an elevation of 3,000 metres. 
The plant here represented is rather a small specimen, and in the collection at 
Glasnevin, Dublin, both leaves and flower-stalks attain a greater length.
