The name Schweiggeria was originally given by Sprengel 

 to a Brazilian shrub, of which he examined specimens in a 

 dried state, and described in his usual unskilful manner. 

 At a later period Von Martius, not recognizing the genus by 

 the former author's character, called it Glossarrhen, from 

 yXcoacrr), a tongue, and appev, a male, in allusion to the pro- 

 cesses which proceed from the front anthers, see fig. 1 . and 

 which look very like the rolled up tongue of a butterflv. 

 The right of priority, however, requires that the first name 

 should be preserved. 



The only two species are bushes inhabiting Brazil ; one 

 of them in mountainous places, and woods in the province of 

 St. Paul's ; the other, which is now figured, in wet shady 

 stony places near the river Itahype in the province of Bahia. 

 They are very nearly Violets ; but differ in having a calyx 

 whose divisions are extremely unequal, three being large and 

 heart-shaped at the base, but not decurrent, the other two 

 being very small and enclosed within the others. The stigma 

 too has a different form from that of Viola. 



Our drawing was made in the nursery of Messrs. Lod- 

 diges, who imported the species. It is a stove shrub, re- 

 quiring the same kind of cultivation as Ixoras and plants of 

 that description. 



Fig. 1. represents the apparatus in the interior of the 

 flower ; that is to say, the stamens with their membranous 

 appendages, and the two tongue-shaped processes, and the tip 

 of the style surmounted by a two-pronged stigma. 



M. Auguste de St. Hilaire seems to doubt whether there 

 is really more than one species of this genus ; but it is evident 

 that the plant he has figured under the name of Schweiggeria 

 floribunda in his Plantes remarquables du Bresil et du Para- 

 guay must be different from this, if any dependence can be 

 placed upon his drawing of the labellum. The species dis- 

 tributed from the Vienna herbarium, under the number 192, 

 appears to be the latter.
