This species has a double interest as being the first known of the 

 genus, and also the basis of tlie identification of Manettia with 

 Lijgistum and Petesia (P. Lygistuni; see historical introduction, 

 supra). According to Alexander the flowers are " deep blue." It 

 is essentially a West Indian species, and is distinguished from its 

 allies bj the manifestly apiculate stipules, the nearly orbicular leaves, 

 and the narrow, rather elongated calyx-lobes, curling and more or less 

 setaceous at the tip. K. Schumann, in the Flora Prasiliensis, treats 

 several of these allied species as varieties of M. Lygistum ; but their 

 characters seem well worthj^ of the specific rank to which Sprague 

 (Bull. Soc. Herb. Boiss. ii. v. (]90o)) has assigned several of them; 

 among these the latter author has properly recalled Willdenow's 

 M. picta {3f. alba, infra), a native of Guiana.

Discovered in Guiana nearly a century and a half ago by Aublet, 

 this species has not yet been recorded elsewhere — unlike the widely- 

 distributed 3f. coccinea, also the discovery of Aublet, the only other 

 native Guianan syjecies (infra). Its most notable character is tiie 

 short, stout corolla, densely hairy in the mouth (see Richard's excellent 

 figures quoted). This connects the J/. Li/r/istum-group with tliat 

 species-group characterized by a short infundibular corolla, by way of 

 M. barbata.
