monograph of Euphorbia and its allies, published in the 

 fifteenth volume of De Candolle's ' Prodromus.' The genus 

 as there constituted consists of two species, a Natal and Mada- 

 gascar one ; these being described from dried specimens are 

 necessarily difficult of recognition, and S. Grantii is evidently 

 closely allied to the Natal S. arborescens, but according to 

 Boissier's careful description that must be a much smaller 

 plant in all its parts, with longer petioles ; and the involucre 

 in our species differs from it, and indeed from the generic 

 character, in being entire. 



8. Grantii was found by Captain Grant near villages in 

 lat. 3° 15' N., in February, 1862, and there only. The Kew 

 plant flowered in November, 18G6. 



Descr. An erect bush, six to ten feet high, with a stout, 

 terete, green stem, few very thick, erect branches, and co- 

 lumnar branchlets thicker than the thumb. Leaves scattered, 

 three to four inches long, obovate-spathulate, obtuse, not 

 very succulent, quite entire, dark green above, paler below. 

 Cymes axillary, corymbosely branched, six to eight inches 

 long, sparingly dichotomously, green. Pedicels purplish. 

 Floral leaves or bracts appressed, obtuse, tomentose, green. 

 Involucre a quarter of an inch in diameter, consisting of an an- 

 nular, tomentose, red-purple cushion, on the inner margin of 

 which are five broadly-oblong, pubescent, toothed, erect scales. 

 Stamens on separate cymes from the pistils, twenty to thirty, 

 with purple anthers and fimbriate calycules at the base of 

 their pedicels. Styles green, with bifid recurved stigmas.
