464 HYDROPHYLLACE^E hydrophyllum 



or slender embryo in cartilaginous or firm-fleshy albumen. 



Tribe i Ovary and capsule strictly 1-celled, lined with a pair 

 of expanded placenta?. Capsule loculicidally dehiscent 



1 Hydrophyllum Root perennial or biennial : leaves all alternate : calyx 



nearly unchanged in fruit : style and stamens exserted. 



2 Nemophila Root annual : some or all of the leaves opposite : calyx en- 



larged in fruit : stamens and style shorter than the corolla. 



Tribe ii Ovary either strictly 1-celled or 2-celled by the meet- 

 ing of the narrow placentae in the axis. 



* Leaves all or all but the lowest alternate. 

 +■ Style 2-cleft, at least at the apex. 



3 Phacelia Corolla not yellow, deciduous: stamens equally inserted low 



down on the corolla. 



4 Emmenanthe Corolla yellow or yellowish, persistent : stamens equally 



inserted low down on the corolla. 



5 Conanthus Corolla purple, deciduous, funnelform; the slender fila- 



ments unequally inserted more or less high up on its tube. 



+- +■ Style and even the stigma entiie. 



6 Romanzoftia Corolla white or pink, funnelform ; the stamens inserted 



on the base of the tube. 



* * Leaves and 1-flowered peduncles all radical : style 2-cleft at 

 the apex. 



7 Capnorea Corolla campanulate or rotate, with the stamens inserted 



on its base. 



Tribe hi Ovary completely or incompletely 2-celled. Cap- 

 sule loculicidal bearing the half dissepiments on their middle. 



8 Is am a Mostly low herbs : capsule membranaceous, the valves and pla- 



centae undivided. 



9 Eriodictyon Shrubby plants: capsule, crustaceous, loculicidal then 



septicidal, thus apparently 4-valved. 



Tribe 1 Hydrophyllese B. & H. Gen. ii, 825. Calyx sometimes 

 appendaged at the sinuses. Corolla mostly convolute in the bud. 

 Style more or less 2-cleft at the apex. Ovary hispid, at least at the 

 apex, strictly 1-celled, lined with expanded, at first fleshy, at matur- 

 ity thin and membranaceous placentas, which form a lining to the 

 pericarp, and enclose the 4 or more amphitropous ovules. Capsule 

 globose, Seeds by abortion commonly fewer than ovules, globular or 

 angled by mutual pressure: albumen cartilaginous. 



1 HYDROPHYLLUM Tourn. L. Gen. n. 204. 



Perennial herbs with alternate petioled and lobed or divided 

 leaves and small flowers in terminal scorpioid racemes or heads 

 on long naked peduncles. Calyx early open, without appendages 

 at the sinuses, nearly unchanged in fruit. Corolla campanulate, 

 the tube within bearing a linear longitudinal appendage opposite 

 each lobe with infolded edges, forming a nectariferous groove.
