A shrub, three to iive feet, almost glabrous ; branchlets very 

 slender; leaves closely approximated, obovate, and somewhat 

 cuneate, slightly concave, but otherwise flat, pointless, quite 

 entire, the conspicuous oleigerous glandules particularly visible 

 beneath ; flowers short-pedicellate ; bracteoles soon mucli shorter 

 than the flowers, cymbous-ovate, fugacious ; calyx-tube turbinate- 

 semiovate, ten-striate and five-plicate ; calyx-lobes nearly thrice 

 shorter than the petals, semiorbicular, entire or nearly so; 

 petals almost orbicular, imperfectly denticulated ; stamens about 

 seven, much shorter than the petals ; anthers roundish, dark- 

 colored, opening by slits ; filaments at least twice as long as the 

 anthers; style much shorter than the stamens ; stigma depressed ; 

 ovules several. 



Differs from T. saxicola in shorter pedicels, in upwards less 

 dilated calyx-tube, in denticulated petals, which reach further 

 beyond the calyx-lobes, and in proportionately shorter stamens. 

 It is separated from T. EllioUii by less thickness and more 

 broadness of leaves, by much more disproportion between the 

 length of the calyx-lobes and petals, and by not absolutely defin- 

 ite number of stamens.
