204 BORAGINACEAE. 



298. HYDROPHYLLUM. WATERLEAF. 



Perennial herbs; leaves long-petioled, mostly pinnately-parted ; 

 flowers white or violet, in cymose dense clusters; calyx 5-parted 

 into narrow divisions; corolla bell-shaped, a nectariferous grooved 

 appendage opposite each lobe ; stamens and style exserted beyond 

 the corolla-lobes; ovary lined with dilated and fleshy placentae; 

 ovules 4; capsule 2-valved, 1-4-seeded. 



Flowers blue, in dense clusters. H. capitatum. 



Flowers whitish, in looser clusters. H. albifrons. 



Hydrophyllum capitatum Dougl. Rootstocks short, with long fascicled 

 fleshy roots; stems exceeded by the leaves, 10-30 cm. high; leaves ovate, 

 5-10 cm. long, soft-hairy, pinnately parted or divided into 5-7 lobes or divi- 

 sions, these cuneate, obovate, entire or coarsely toothed or cleft; petioles 6-12 

 cm. long, generally longer than the blades; peduncles shorter than the petioles; 

 inflorescence a dense round cyme, 2-4 cm. broad; calyx hispid, the divisions 

 lanceolate, without appendages in the sinuses; corolla blue. Moist stony 

 places, common. 



Hydrophyllum albifrons Heller. Roots densely fascicled; stems 30-40 cm. 

 high, exceeded by the leaves, sparingly hairy; leaves 10-20 cm. long, pinnately 

 5-7-divided; divisions ovate, incisely and coarsely cleft and toothed, 3-6 cm. 

 long; lower petioles elongated; inflorescence a rather dense cyme, exceeding the 

 leaves; calyx soft-hispid, deeply 5-parted into lanceolate divisions without 

 appendages in the sinuses; corolla whitish. In low copses common. 



299. NEMOPHILA. 



Diffuse and tender annual herbs; leaves opposite or partly 

 alternate, pinnatifid or lobed; peduncles terminal or lateral, 

 1-flowered, slender; calyx enlarging more or less in fruit, 5-parted, 

 with a reflexed appendage at each sinus ; corolla rotate or nearly 

 campanulate, deeply 5-lobed, the throat appendaged more or 

 less with 10 internal scales or plates; stamens and style shorter 

 than the corolla; ovules 4 or many; capsule similar to the pre- 

 ceding, ripening 1-16 seeds. 



Nemophila breviflora Gray. Whole plant sparsely hirsute, erect when 

 young, later prostrate; stems 5-40 cm. long; leaves alternate, 1-2 cm. long, 

 pinnately 3-5-parted, the divisions oblong-lanceolate, acute, entire; peduncles 

 about equalling the petioles; calyx appendages much smaller than the proper 

 lobes, both ciliate; corolla campanulate, white, shorter than the calyx lobes; 

 internal appendages cuneate, fringed at the summit; ovules four; seed solitary, 

 nearly filling the capsule. On the highest mountains. 



Family 78. BORAGINACEAE. BORAGE FAMILY. 



Mostly rough-hairy herbs; leaves alternate, entire, without 

 stipules; flowers regular, perfect ; calyx 5-parted; corolla 5-lobed, 

 sometimes with projecting appendages (fornices) in the throat; 

 stamens 5, inserted on the corolla-tube; style 1; ovary usually
