seldom, if ever, sufficient water to float them, and they are often found 

 on perpendicular rocks, down which the water trickles. 



Some of the European species have been employed medicinally, 

 but their use is now almost, if not quite, discontinued. 



Nimaber of species about 180, 



Calyx of 2 sepals. Utricles blaader-like, ovoid or 



globose. Utricdlaria. 



Calyx deeply 5-partite. Utricles tubular with 2 spirally 



twisted arms. Genlisea. 



ORDER CXIX. GESNERACE^. 



Another small Order, one genus only of which is represented in 

 our flora. Plants of the family have little, if any, economic value ; 

 but many are highly ornamental, and are largely cultivated for their 

 beauty. From Streptocarpus Wendlayidii of Natal, and 6\ Dunnii of 

 Transvaal, hybrids of great excellence have been produced, and are 

 now in cultivation in Europe. Other species have also been utilised 

 for the same purpose. 



Number of species about 700. 



Stemless herbs, with scape-like peduncles. 



Streptocarpds.

ORDER CXX. BIGNONIACEiE. 



An Order confined to tropical and subtropical countries, and 

 quite absent from Europe. Many of the species are cultivated for 

 ornament ; and in their native countries some have been used medi- 

 cinally. Jacaranda mimosaefolia, in addition to being a very orna-
