 Calyx glandular and Hoccose. Corolla blotched and

 Corolla tubular-campanulate 5-6-lobed, puberu- 

 lons inside. Stamens 10-12, finely puberu- 

 lous at base. Leaf mat on both surfaces or 

 somewhat glossy underneath. Petiole tloccose

Calyx glandular and jjuberulous, rarely gland-

 Corolla widely tubular-campanulate 7-lobed, 

 puberulous inside. Stamens 14, pubescent to 

 middle. Leaf mat on l)oth surfaces or some- 

 what glossy underneath. Petiole glandular

Agastum. 



The two species included here are alike in foliage-form 

 but differ in many other characters. The leaves are rigid, 

 long, narrow, oblong, and blunt, with an abrupt beak-point, 

 the surface mat on both sides, the under-leaf punctulation 

 very evident. One of them (Rh. agastuoii) tends to 

 eglandular indumentum, the other (Rh. eritiinum) to be 

 glabrous. The largo red flowers form a large compact 

 truss, and the corolla is conspicuously 7-lobed but is some- 

 times only 5-lobed in Rh. agastum, and the stamens which 

 ought to be and are 14 in Rh. eritiraum are only 10-12 in 

 Rh. agastum ; I have not found a flower of this with 14 

 stamens, nor have I seen a 6-lobed corolla. One species is 

 from the Chungtien plateau in the far N.W., the other 

 from the Shweli-Salween divide in the W. As they 

 stand, one can hardly speak of them as allied within the 

 series to which they both certainly belong; they are only 

 alike in shape of leaf. Perhaps uniting links may be 

 found. For purposes of recognition in the series it is 

 convenient to place them together.
