This species is of particular interest as representing the earliest 

 j)ublished recognition of the generic identity of Vellozo's Guagnehina 

 and Ma)iettia (see Introduction, supra, p. 3).

This species has been well distinguished by the author in his 

 description, cited above. A further interesting feature, which seems 

 to me to be critical, is the presence of long tapering jointed hairs, 

 that compose the indumentum of the outside of the corolla in 

 M. injlata. The corresponding hairs in M. luteo-ruhra are short, 

 relatively broad, and one- (at most two-) celled. As the author 

 points out {loc. cit.'), M. injlata is confined to Paraguay and 

 Uruguay; while M. luteo-ruhra is essentially a native of tropical 

 Brazil.

The large, bulbous flowers, with ample spreading calyx-lobes, are 

 striking featm*es.

This species is transitional, in the characters of the small size and 

 sub-hypocrateriform shape, between § Heterochlora and § Lygistum, 

 •approaching the latter in the mode of grouping of the flowers (see 

 Introduction, jDp. 5, 8).
