464 % HYDROPHYLLACEA HYDROPHYLLUM 
or slender embryo in cartilaginous or firm-fleshy a]bumen. 
TriIBe 1 Ovary and capsule strictly 1-celled, lined with a pair 
of expanded placente. 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 1t Ovary either strictly 1-celled or 2-celled by the meet- 
ing of the narrow placente 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, funnelfurm; the slender fila- 
ments unequally inserted more or less high up on its tube. 
+ + Style and even the stigma entire. 
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 1 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- 
centze undivided. 
9 Eriodictyon Shrubby plants: ss psg crustaceous, loculicidal then 
septicidal, thus apparently 4-valved. 
Tribe 1 Hydrophyllee B. & H. Gen. ti, 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 ut the 
apex, strictly l-celled, lined with expanded, at first fleshy, at matur- 
ity thin and membranaceous placentx, 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.
