9. Stems irregularly branched; leaves squarrose, or erect-spreading (mostly larger 

 and robust species.) 



19. H. triqu^trum, L. [Three-sided] : Stems 3 to 5 inches 

 high, nearly erect, sparingly divided, firm, the divisions thickened 

 at their tips, pinnate ; branchlets somewhat recurved, attenuated ; 

 leaves squarrose, triangular-lanceolate, acuminate, serrulate, stri- 

 ate, 2-nerved at base ; capsule oblong-ovoid, nodding ; pedicel about 

 J of an inch long ; lid conic, apiculate. Woods, on the ground. 



{j 10. Leaves rather squarrose, stellately expanding at the summit of the branches.
