260 HYDROPHYLLACEAE 



commonly linear or oblong in outline, once or twice pinnately and (for the most 

 part) finely dissected, the ultimate segments V2 to 3 (or 11) lines long; petioles 

 ^ to 1 inch long, or the uppermost leaves sessile ; racemes scattered, solitary or 

 geminate, at maturity divergent, often subtended by the upper leaves ; calyx-lobes 

 unequal, lanceolate, oblanceolate or narrowly oblong, rarely linear ; corolla rotate- 

 campanulate, sordid white, blue, or violet, 3 to 4 lines long, its scales short, strongly 

 lobed or broadened at the middle, spreading transversely and so curved as to be 

 a little dome-shaped or inversely bowl-shaped, at base united to the filaments and 

 thus forming a slight sac behind the filaments; stamens shorter than the corolla or 

 a little esserted ; fruiting pedicels ascending ; capsule globose, hairy to at least be- 

 low the middle.
