284 HYDROPHYLLACEAE 



lineate wing or margin. Ovary l-celled, each placenta 2 or 3-ovuled. Styles 2, 

 distinct to the base, short. Capsule membranous, 2-valved. Seeds 4, roughly pit- 

 ted. — Species 1. (J. G. Lemmon, a pioneer botanical explorer of California.) 



Note on relationships. — The tube of the corolla of Lemmonia californica is very short but 

 distinctive and rather conspicuous. It is constricted at the top, at the point of stamen attachment. 

 The bowl-shaped throat, markedly expanding above the tube, is twice as long as the tube. The 

 ovary and capsule, described by Gray (Proc. Am. Acad. 12:162; Bot. Cal. 2:468) as 2-celled, are 

 really 1-eelled with closely parietal narrow placentae. In no way does Lemmonia differ in fruit 

 from the species of Nama as a whole. Indeed, Lemmonia californica resembles Nama pusillum 

 so closely that for the generic validity of Lemmonia one must look to the corolla character newly 

 described above and to the peculiar structure joining the bases of the filaments. In all other 

 essential respects, in habit, aspect, foliage, inflorescence and capsules, the similarity of Lemmonia 

 californica to Nama pusillum is remarkable. Lemmonia as a genua rests mainly on two slight 

 technical characters — that of the corolla-tube and the dilation-joined filaments. 



1. L. californica Gray. Plants prostrate or diffuse, forming dense circular 

 mats 3 to 9 inches broad; herbage pitberitlent; leaves rosulate at base, the blades 

 spatulate, entire, 3 to 9 lines long, tapering into a short petiole ; flowei's solitary in 

 the forks and crowded at the ends of the branches ; calyx-lobes subfiliform or nar- 

 rowly linear, densely white-hairy, in fruit twice the length of the capsule ; corolla 

 white, 5-lobed, 1^4 lines long, not exceeding the calyx-lobes; ovary densely hairy at 

 summit ; capsule slightly 2-lobed, 1 line long.

10. NAMAL. 



Low herbs. Leaves alternate, entire in ours (except N. rothrockii). Flowers 

 purple, bluish or white, borne in terminal mostly dense clusters or cymes, or some- 

 times solitary in the axils. Calyx deeply 4 or 5-parted. Corolla funnelform, the 

 tube without scales. Stamens included, commonly unequal and unequally inserted 

 on the middle or lower part of the corolla-tube (or the insertion often only very 

 slightly unequal). Styles 2, distinct, or united except at apex. Ovules 2 to 70 to 

 each placenta. Capsule thin-%valled, 2-celled (the 2 thin parietal placentae meeting 

 in the axis) or incompletely 2-celled (the placentae only approximate), finally de- 

 hiscing into 2 entire valves (or in N. lobbii into 4 valves).- — Species about 35, North 

 and South America and Hawaiian Lsls. (Greek nama, a spring.) 



Leaves of one kind ; stems herbaceous ; capsule 2-valTed. 

 Leaves entire ; annuals. 



Styles more or less connate. 



Ovary superior; leaves more or less petioled, not clasping; calyx-lobes linear, 

 straight. — Subgenus Conanthus. 



Corolla 4% to IV^ lines long; styles 3 lines long 1. N. aretioides. 



Corolla 1% to 214 lines long; styles % line long 2. N. densum. 



Ovary half -inferior ; leaves sessile, the upper clasping; calyx-lobes very narrow but 

 spatulate-dilated at tip, in fruit accrescent, spreading or recurved at tip, 



the midnerve strongly thickened. — Subgenus Zonolacus
