NOTES ON TWO CALIFORNIA NEMOPHILAS 



^^Nemophila Menziesii var. annulata, var. nov. — Plants slender, pros- 

 trate, very brittle: cotyledons with oval blade and slender petiole: leaves 

 rather less divided than in N, Menziesii^ mostly 5-lobed, the upper greatly 

 reduced but showing less tendency to become entire than in the variety 

 integrijolia Parish : peduncles usually twice or more exceeding the leaves, 

 often flexuous; flowers usually about or rather less than i*^^ across; calyx- 

 lobes obtuse; corolla pale blue to almost white, with a deep-purple irregular 

 ring above the scales, seldom dotted or hairy toward the center within; 

 scales from 0.2 to i^^ long, attached by one whole side or free at the tip 

 (seldom as much as half free), ciliate with stiff bristles, which are often as 

 long or longer than the scale is wide. 



*j 



This variety is distinguished from the type by the greatly reduced size, 

 lighter color, and peculiar markings of the corolla; the fewer-lobed, smaller 

 leaves; the oval cotyledons ; and the more delicate habit. From the variety 

 integrijolia it is distinguished by the smaller size and the markings of the 

 corolla ; the lack of hairs within the corolla ; the somewhat longer peduncles ; 

 the rather more divided leaves; and especially bv the corolla scales (cf. 

 note to N. Menziesii integrijolia^ Box. Gazette 34:205, 1902), 



This is the first Nemophila reported from the desert regions of Cali- 

 fornia, It was found among rocks at Dead Man^s Point, near Victornlle, 

 on the Mojave desert. The type collection is Hall and Chandler, no. 6769 , 

 and the type specimens are in the herbarium of the University of California. 



Nemophila Menziesii var. rotata (Eastw.), comb, nov, — Very close to 

 the variety integrijolia Parish, with which I united it in my Revision of the 

 Genus Nemophila (BoT. Gazette 34:194). The examination of more 

 abundant material seems to justify the retention of the form as a separate 

 variety. It differs from the variety integrijolia chiefly in the smaller flowers 



(usually less than 



I 



cm 



across), which are usually of much deeper blue and 



nearly or quite rotate. The sinuses of the corolla are comparatively deep 

 and the lobes comparatively narrow. The scales are oblong-linear, deeply 

 laciniate, and attached by the narrow base only. So far as seen, the corollas 

 were not dotted toward the center, but were covered with long hairs at the 

 base within. 



The range of this variety seems to be restricted to the vicinity of San 



California
