 Stajidishii (Standish's) ; resembles the last, but has more slen- 

 der and less silvery foliage ; Japan ; 1861. 



Thunbergia. [Acanthaceae.] Stove evergreen climbers. 

 They thrive best in a mixtifre of turfy loam, peat, and rotted 

 dung ; but the best of them, T. alata, and its varieties, be- 

 ing very liable to attacks of the red spider, are best raised 

 from seeds, and treated like tender annuals, only they re- 

 quire a trellis on which to train their branches. T. alata 

 aurantiaca is the best, having deep orange blossorfs, with a 

 black centre ; T. alata alba, with white flowers and a black 

 centre, is also very pretty, and there are several others ; 

 the color of T. alata itself is buff-yellow, with a black centre. 

 The varieties all bloom throughout the summer, and at that 

 season are splendid objects in a greenhouse, if well man- 

 aged : they may also be grown out-doors, and are very beau- 

 tiful objects in the garden, preferring moist peat soil. All 

 of the species, strike freely ; and cuttings in sand, under a 

 bell-glass, v/ith a little bottom-heat, are rooted in a short 

 time. The seeds may be sown in March, in wide-mouthed 

 pots, and as soon as the plants are large enough, potted off 

 in the smallest-sized pots, to be treated the same as cut- 

 tings ; or planted in the borders in May.
