4. H. syrmanthera, Hiern. Glabrous except the inflorescence. 

 Branchlets snbterete, rather thickened at the nodes. Leaves elliptical, 

 acaminate, rather wedge-shaped at the base, thinly coriaceous, 5-6 by 

 2-2 J in. ; lateral veins about 4 pairs ; tertiary veins transverse, 

 slender ; petiole ^ in. ; stipules subtruncate apiculate. Flowers about 

 \ in. long, shortly pedicellate, in short dense axillary cymes ; bracteoles 

 shortly pubescent, the uppermost usually not cup-shaped. Calyx-limb 

 short, rather broad, deeply 4--6-lobed ; lobes ovate, obtuse, densely 

 ciliate. Corolla glabrous outside ; throat pubescent ; limb 4-5-partite ; 

 lobes oval-oblong, scarcely acute, not acuminate. Anthers 4-5, long- 

 acuminate ; filaments rather short. Style glabrous. Ovules about 2

5. T. bracteata, Hiern. Grlabrous except the inflorescence. 

 Branchlets subterete, rather thickened at the nodes. Leaves elliptical, 

 acuminate, rather obtuse at the base, thinly coriaceous, about 4 by

 one side. Calyx puberulous outside, small ; limb deeply 5-6-lobed ; 

 lobes ovate, ciliolate. Corolla glabrous outside, throat bearded ; 

 lobes 5, subapiculate. Anthers apiculate. Style glabrous. Ovules 

 2-5 together.

 Kraussia. Glabrous. Branchlets somewhat compressed towards the 

 extremities. Leaves elliptical, narrowed towards both ends,- obtuse, 

 subsessile, thinly coriaceous, paler beneath, 3-3^ by 1-1^ in. ; lateral 

 veins about 5 pairs, inconspicuous, net-veins marked above ; stipules 

 much apiculate from a subtruncate short base, ^-i in. long; Flowers 

 ^ in. long, shortly pedicellate, about 5-0 together, in short axillary 

 bracteolate subsessile clusters ; upper bracteoles forming a single 

 shortly lobed calyculus ; lower bracteoles often calyculate with one 

 larger foliaceous lobe. Calyx-limb deeply 5-cleft, broader than the 

 ovary ; lobes rounded. Corolla-lobes 5, equalling the tube , throat 

 densely bearded. Anthers 5, connective produced into a narrow claw.
