18. T. hirsuta, T, Anders, in Journ. Linn. Soc. vii. 20. Stem 

 moderately stout, pilose. Leaves broadly ovate, rounded below, obtuse 

 above, covered with stiff hairs on both, sides, with one or two teeth on 

 each margin, \^ in. long, 1 in. broad; petioles 2-3 lin. long. Flowers 

 on pilose peduncles, which attain 3 in. in length ; bracteoles cordate,

19. T. Gibsoni, S. Moore in Journ. Bot. 1894, 131. Stem and 

 leaves unknown, the latter said to be ovate. Flowers on pubescent 

 peduncles 3 in. long ; bracteoles large, ovate, very shortly acuminate, 

 covered outside with short, rather stiff hairs, puberulous within, at 

 flowering 1|- in. long, 10 lin. broad. Calyx-teeth fairly long. Corolla- 

 tube IJ in. long; lobes J in. long, retuse, orange-yellow with a waxy

Wile Xiand. British East Africa : Mau, in a damp spot at 8200 ft., Gibson! 



It is probably safe to place this species very near to T. alata and T. Erythrace. 

 All that was collected consists of two flowers with their peduncles, which are preserved 

 in the British Museum.
