464 HYDRO PHYLL ACE AE hydrophyllum 



with a close and usually reticulated or pitted coat, and a small 

 or slender embryo in cartilaginous or firm-fleshy albumen. 



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

 of expanded placentae. Capsule loculicidally dehiscent. 



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



nearly unchanged in fruit; style and stamens exserted. 



2 Nemophlla 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 

 meeting 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 entire. 



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



on the base of the tube. 



* * Leaves and 1-flowered peduncles all radical : style 3-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 Nama 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 Hydrophylleae B. & H. Gen. ii, 825. Calyx sometimes 

 appendaged at the simises. Corolla m,ostly convolute in the hud. 

 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 

 maturity thin and membranaceous placentae, which form a lining 

 to the pericarp, and enclose the -k or more amphitropous ovules. 

 Capsule globose. Seed's by abortion commonly fewer than ovules, 

 globular or dngled by mutual pressure: albumen cartilaginous. 



1 HYt)ROPHYLLUM Tourn. L. Gen. n. 204. 



Perennial herts 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.
