With the exception of Regnellia purpurea and Bletia 
Rodriguesu, all of the above names have previously been 
referred to the inadequately described Bletia catenulata 
Ruiz & Pav. 
The concept Regnellia purpurea, being a true Bletia 
and widely different from Bletia purpurea DC., was 
given the name Bletia Rodriguesii by Cogniaux. 
The plant which Reichenbach filius (in Bonplandia 4 
(1856) 216) attributed to B. catenulata, was cited by 
Cogniaux as Bletia Rodriguest (confined to Brasil). B. 
Rodrigues is said to differ from B. catenulata in having 
narrower leaves, more obtuse petals, and more rounded 
lateral lobes of the lip which has three yellow lamellae in- 
stead of four white lamellae through the center. In the 
first place, the breadth of leaf, which is a variable char- 
acter, Is separated by only 5mm. in the two contrasting 
species, according to the descriptions. Secondly, the pet- 
als of Peruvian specimens referable to B. catenulata are 
commonly broadly rounded at the apex (sometimes with 
a minute point at the tip). Again the lateral lobes of the 
lip are more or less broadly rounded at the apex, as in 
B. Sherrattiana from Colombia which was referred by 
Schlechter to B. catenulata. Finally, all of the Peruvian 
specimens of B. catenulata examined have from three to 
five low approximate thickened central nerves, which are 
‘alled lamellae in the description. B. catenulata is de- 
scribed as having these keels whitish, whereas those of 
B. Rodriguesu are noted as yellow. In all of the Peru-
