 and corolla, the latter plaited in the tube, and 

 with an equally-parted limb, which is generally 

 five cleft ; and an equal number of stamens 

 with broad filaments, and arrow-shaped anthers. 

 The seeds are numerous, and are usually in two 

 follicles. 



The orders Spigeliacese, Loganiacese, and 

 Menyanthacese, have been separated from Gen- 

 tianese, and are adopted by some botanists. 



ORDER CXXX.— BIGNONIACE^. 



The most interesting genera are — Bignonia ; 

 from which Tecoma has been divided by some 

 botanists, on account of a slight difference in 

 the seed-pod ; Jacaranda, said to produce the 

 rosewood of commerce ; Eccremoearpus, and 

 Catalpa. All the plants included in this order 

 have winged seeds, and generally very long 

 horn-like seed-pods. The different species of 

 Bignonia or Tecoma have trumpet-shaped flowers 

 with a five-toothed calyx, and four stamens of 

 unequal length, with the rudiments of a fifth. 

 The capsule is very long and narrow, resembling 

 a silique in shape, but broad on the outside, and 

 the leaves are pinnate. Eccremoearpus^ or Calam- 

 pelis scabra^ is a well-known climber, with orange- 

 coloured, bag-like flowers, which are produced 

 in secund racemes ; large, roundish warted
