Descr. Stem fhrubby ; branches glandulofe -warty. Leaves 

 alternate, linear, flefliy, (lightly mucronate, glandular, clammy. 

 Inflorefcence corymbofe. Pedicles leafy, one-flowered. Calyx 

 ov ate, clammy : leaflets imbricated, keeled, bluntifh, with 

 white membranaceous margins. Common flower radiate, refembling 

 an Achillea; but the radius does not confift of the flofcules, 

 out of the petal-like paleae, Flofcules hermaphrodite, tubular : 

 tube cylindrical, greenifh : limb revolute, white tinged with 

 purple. Anthers united, yellow. Germen oblong-ovate, white, 

 villous, without any pappus. Each floret is embraced by a 

 fingle palea with involute, fcariofe, jagged margins and fmall 

 petal-like termination. In the centre the petal-like appendix to 

 the paleae is very fmall, but gradually enlarges as thefe approach 

 the circumference, and in the outer row, their claw part is 

 more expanded, and does not involve a floret. Thefe may 

 therefore be very well regarded, as compofing the inner
