oD som The type, in the John Donnell Smith Herbarium, was collected at Santa 
6330. Barbara, Department of Solol4, Guatemala, at an altitude of about450 me- 
ters, in flower, January, 1894, by Heyde and Lux (J. D. Smith, no. 6330). 
Another specimen referred to this species was collected between Jalisco and Aurora, 
State of Chiapas, Mexico, by G. N. Collins and C. B. Doyle. 
This species has close affinities with L. atropurpureus Benth., but differs in the 
pubescence, the size of the flowers, the auriculate carinal petals, etc.
