ACANTHACEAE.

deciduous ; corolla 1^ inch, pubescent, yellow, with a brownish 

 tube, tube curved upwards, base cylindric. 

 Strobilorhachis prismaticus = Aphelandra Hydromestus. 

 Thunbergia, L. — This is about the only genus in the order with 

 climbing species ; other genera yield scandent or straggling plants 

 (such as Asy stasia scandens and Adhatoda cydoniaefolia), but not 

 true climbers. All the species have beautiful flowers and are great 

 favourites in our conservatories and stoves. 



affinis, S. Moore, "Jour. Bot." xviii. (1888) 5; (fig. " Bot. Mag." 

 t. 6975). — Tropical Africa. Stem quadrangular, rambling ; leaves 

 elliptic, entire, short-petioled ; flowers subsolitary, corolla violet, 

 tube yellow, curved above the base. The figure in "Bot. Mag." is 

 the variety pulvinata. Closely allied to erecta. 



alata, Hook., "Ex. Fl." t. 177; (fig. "Bot. Mag." t. 2191 and t. 

 3512). — Tropical Africa ; cultivated and run wild in India. Softly 

 villous. Leaves ovate, cordate, petioles winged; calyx 12-cleft ; 

 corolla 1^ inch, the tube curved, limb campanulate. There are 

 several varieties only differing in the colour of the flowers : yellow, 

 yellow with black eye, orange or dark yellow, the same with black 

 eye, pure white. This is a very showy greenhouse climber, and 

 should be grown by everyone possessing a conservatory ; it answers 

 well in very small pots. It is annual, and should be sown early 

 in the spring ; it makes a show all the summer. See also " Flor. 

 des Serres," fig. 415. 



angulata, Hilsenb. & Boj. ex Hook. " Exot. FL" iii. t. 166.— 

 Madagascar. A graceful climber. Leaves broad, angularly cor- 

 date, on very long petioles ; flowers axillary, solitary, opposite, on 

 long peduncles ; bracts 2, large, ovate, 1 -nerved, ciliate ; calyx cup- 

 shaped, multifid ; corolla 1 inch long, tubular, swollen upwards, 

 pinkish- blue. 



atriplicifolia, E. Mey. in "Dreg. Zwei Pfl. Docum." 226.— South 

 Africa. Stems hirsute ; leaves sessile, lower ones ovate, obtuse, 

 with mucro, upper oblong, acute ; corolla yellow, infundibuli- 

 form, tube narrow, limb spreading. Allied to capensis. 



Lately introduced. Not a good grower. I have not succeeded 

 in flowering it, though I have had it for two years. 



Capensis, Retz in " Phys. Sell. Handb." i. 1776, 163 ; (fig. Lodd. 

 "Bot. Cab." t. 1529). — Cape of Good Hope. Leaves nearly round, 

 toothed, obtuse ; petioles very short, hairy ; flowers yellow ; calyx 

 tubular- campanulate. 



Chrysops, Hook. (fig. " Bot. Mag." t. 4119).— Sierra Leone. Leaves 

 cordate, angular.; calyx truncate ; corolla campanulate, infundibuli- 

 form, the tube yellow, much contracted at base, limb purple ; 

 peduncles axillary, solitary, 1 -flowered, shorter than the leaves.

COCCinea, Wall., "Tent. FL Nep." 49, t. 37; (fig. "Bot. Mag." 

 t. 5124). — India and Burma. Leaves elliptic, toothed ; racemes 

 lax, pendent, elongate, up to 18 inches ; bracts 1 inch ; calyx a 

 rim only ; flower red, tube 1 inch long. Frequently grown in 

 our stoves.
