Hydrolea,| | LXXXVIII. HYDROPHYLLACER (BAKER AND BROWN). 3 
inserted at the sinuses of the corolla ; filaments fiilform, usually dilated at 
the base; anthers sagittate. Ovary 2- (rarely 3-) celled; placentas 
fleshy, adnate to the dissepiments; ovules many in a cell; styles 2, 
distinct from the base, subulate; stigmas simple or capitate. Capsule 
globose, ellipsoid or ovoid, membranous, usually septicidally 2-valved. 
Seeds many, minute. Herbs or undershrubs, sometimes spinous, 
glabrous or softly glandular-pilose. Leaves alternate, entire. Flowers 
blue, usually in peduncled bracteate cymes, which form a panicle, some- 
times in axillary clusters or racemes. 
Species, about 20, spread widely in the Tropical and Temperate regions of both 
hemispheres. 
All the following species are herbaceous, without spines,

Allied to H. zeylanica, Vahl, but easily recognised by its more clustered flowers 
and much shorter pedicels.
