 segments spinous, without long white hairs. Corolla blue, very thinly

 IJ by h in., narrow elliptic, spinous-margined ; sterile shoots in their 

 axils (as well as the lowest floral-leaves) reduced to simple spines

 leaves. One-flowered branches (reduced spikes) 2-^ together, axillary 

 or themselves grouped into short ovoid spikes; flower-bract § by nearly

In this species and its allies the axillary sterile shoots, above the 4-whorled leaves, 

 begin with simple spines (in place of leaves) and develop into the flower-spikes of the 

 next season, at the foot of which these simple spines persist as the lowest floral-leaves. 

 The very different group of Blepharis, wherein the lower jiair of each whorl of 4 stem- 

 leaves is reduced to compound (or even simple) spines, has been confused herewith. 



28. B. grandis, C. B. Clarke. Branches stout, glabrate. Leaves 

 in distant whorls of 4 (outer pair rather shorter) up to 5J by 1 in., 

 spinous-margined, glabrous; petiole i in. long. Heads of 1-flowered 

 branches (reduced spikes) several, axillary and terminal, 2-3 in. in diam., 

 globose, dense, softly hairy; bracts lanceolate, softly spinous; bracteoles 

 ^ in, long, linear. Two outer calyx-segments J in. long, lanceolate ; 

 2 inner J in. long, narrow-lanceolate. Corolla \\ in. long, fine blue, 

 shortly hairy within and without. Pistil glabrate ; 2 pits filled with 

 glands at the style-base.
