HYDROPHYLLACE^E. 251 



-i H Corolla broadly funnelform above the short tube. 



12. L. grandiflorus (Benth.), Greene. Very rigid and strict, % 1% 

 feet high, the rigid linear-subulate leaf-segments 5 11, ascending, 

 spinulose-serrulate on the margin and toward the base somewhat ciliate : 

 corolla lilac; tube little exserted; limb more than ^ inch broad. At 

 Alameda, San Francisco, and southward. June, July. 



6. PHLOX, Linn. Opposite-leaved herbs with usually cymose and 

 terminal inflorescence; differing from the last genus in that the stamens 

 are unequal and unequally inserted on the upper part of the tube of the 

 salverform corolla, and the leaves not rigid nor palmatisect. Our only 

 species belongs to a chiefly Texan group of annuals with a scattered 

 inflorescence: the upper leaves being alternate. 



1. P. gracilis (Dougl.), Greene. Only a few inches high, pubescent: 

 lowest leaves obovate; upper lanceolate: corolla less than ^ in. long, 

 rose-purple; tube hardly exceeding the linear calyx-lobes; limb only 2 

 lines broad. Not rare in the more hilly districts. April, May. 



OEDEB LXXI. HYDROPHYLLACE^E. , 



Ours (with the exception of one gummy coriaceous-leaved shrub) 

 herbs remarkable for much of the hispid and rough in pubescence, coin- 

 cident with a thinnish and juicy herbage; the juice watery and without 

 special properties. Leaves exstipulate, often pinnately lobed or dis- 

 sected. Flowers complete, 5-merous, very often in unilateral and 

 scorpioid false racemes or spikes. Calyx persistent, of 5 deep lobes or 

 distinct sepals. Stamens borne on the tube of the corolla, alternate with 

 its lobes. Ovary not lobed or divided, 1- or 2-celled; the 2 styles distinct 

 at apex if not throughout (except in Romanzoffia}. Fruit capsular; the 

 2 placentae parietal, or borne on the half-partitions. 



* Ovary 1-celled, the placentx forming a sac-like lining to the ovary-walls. 



Seeds uniform, globular or ovoid NEMOPHILA 1 



" not uniform within the capsule EUCRYPTA 2 



* * Placentse narrow, not lining I he cell, sometimes almost 

 partitioning it into two. 



Style-cleft at apex, or to the middle; 



Corolla blue or white, deciduous PHACELIA 3 



yellow, persistent EMMENANTHE 4 



Style and stigma entire; flowers white ROMANZOFFIA 5

1. NEMOPHILA, Null. Diffuse annuals with tender herbage, pin- 

 nately lobed or divided leaves, and axillary peduncles usually 1-flowered. 

 Calyx 5-parted, usually with a supplementary reflexed lobe at each sinus. 

 Corolla deeply 5-lobed, broadly campanulate to nearly rotate, convolute
