igS CLASSIFICATION 



sensitive leaves forming a leaf-mosaic, and bright- 

 yellow flowers which remain closed in bad weather, 

 fertilizing themselves cleistogamously ; kamranga 

 {AverrJioa Carambola), a tree with sensitive leaves 

 and five-angular exceedingly acid fruits, and often 

 trimorphic flowers; dopati {Impatiens Balsamma), a 

 herb cultivated in gardens for its showy often varie- 

 gated flowers — the capsules (see fig. 79) of it dehisce 

 elastically expelling the seeds to a distance, and 

 the valves twist upon themselves like a corkscrew ; 

 ban-narenga or lak-chana {Biophytum sensittvum), a 

 common weed on roadsides, with a rosette of sensitive 

 pinnate leaves and dimorphic flowers (the flowers 

 of all Biophytum are as a rule dimorphic); Hydrocera 

 triflora, a common water-weed with fistular floating 

 stem; Pelargonium or Garden Geranium, a com- 

 mon garden herb grown for its handsome spurred 

 flowers; Garden Nasturtium (Tropceoluvi majus), a 

 trailing as well as twining herb of gardens, climbing 

 by twisting its petiole round the support, with glabrous 

 round peltate leaves, and orange-red large spurred 

 protandrous bee-flowers provided with nectar-guides. 

 When the flower opens, the stamens are seen curving 

 downwards with the anthers still unripe, the style 

 still short, and the stigma closely apposed. The 

 stamens as they mature become erect one by one, 

 shed their pollen-grains exactly opposite the flower 

 entrance, and then again curve downwards. The 

 style in the meantime becomes so long that the mature 

 stigmas take up the position previously occupied by 

 the dehiscing anthers. An insect visiting first a 

 young flower and then an older one will necessarily 

 transfer the pollen of the first flower to the stigma of 

 the latter. The leaves of this plant have water-pores 

 in their margin (see fig. 43). Compare in this respect
