11. N. mitracarpa Greene. Stem with few to several slender branches from 

 or near the base, 2 to 10 inches high, erect or sometimes diffuse, sometimes reduced 

 to a short stem (1 inch hig-h) and a single head; herbage puberuleut; leaves i/^ to 

 11/2 inches long; lower leaves (sometimes only the very lowest) pinuately divided 

 so as to be remotely and regulai'ly pectinate, the segments short-acerose, entire, cus- 

 pidate, 1/2 to iy2 lines long; upper leaves pinnately divided, the acerose segments 

 bipartitely lobed, the terminal segment (in all or some of the leaves) oblaneeolate 

 with the margin cut into upwardly pointed laciniae; bracts glandular-pubescent, 

 similarly twice piunatifid but with the terminal segment oblaneeolate, its margin 

 laciniately toothed; calyx about % as long as corolla, its lobes nearly twice as long 

 as the calyx-tube, entire or 1 or 2 of the longer lobes toothed ; corolla blue, S^/o to 5 

 lines long, the tube white, filiform, the throat ample, yellowish above and white 

 below, about as long as corolla-lobes or a little shorter, the limb 2 to 2i/4 lines broad ; 

 stamens inserted at base of corolla-throat; capsule 4-angled at summit, 1-celled, 

 1-seeded, 4-valved; apex of capsule with a papilla-like apiculation; cotyledons as 

 if 6, each of the 2 cotyledons deeply parted into 3 lobes.

Field note. — In southern San Benito and Monterey counties and in northern San Luis Obispo 

 County in the drainage basin of the upper Salinas River, is an area inhabited by a Navarretia of 

 quite constant aspect. Its stems are slender and erectly or somewhat corymbosely branched from 

 the base ; the terminal segment of the pinnatifid leaves tends to be lanceolate with upwardly- 

 pointed marginal laciniae; the heads are somewhat glandular and rather constantly uniform in 

 size. This plant has been described as Navarretia jaredii Eastw. (1900), but it agrees in every 

 detail of habit, flower, fruit and embryo with an isotype of Navarretia mitracarpa Greene (1887). 



Navarretia mitracarpa was first collected in June, 1884, by M. K. Curran, "somewhere in Lake 

 County." On account of the disorderly habits of the collector, M. K. Curran, in handling and 

 labeling plant materials, and by reason of the fact that Navarretia mitracarpa has not since 1884 

 been collected in Lake County, it is a natural query whether the type specimens may not liave come 

 from Monterey County. On the other hand, this is to be said: an itinerary of M. K. Curran (K. 

 Brandegee), although compiled from doubtful, incomplete, fragmentary and sometimes contradic- 

 tory records, seems to show that M. K. Curran was definitely in Lake County in June, 1884, and 

 it is here suggested that Navarretia mitracarpa should be sought for on or near Kelsey Mountain. 



In Lake County and in southwestern Colusa County a Navarretia resembling Navarretia 

 mitracarpa has been frequently collected and labeled as that species. It is a coarser plant than 

 Navarretia mitracarpa, has a prostrate habit, finely bipinnatifid leaves and larger heads. It dif- 

 fers from Navarretia mitracarpa also in details of flower and capsules. It is a different thing 

 and is described below as new. 



The representation of Navarretia mitracarpa in the South Coast Ranges is distinguished by 

 an outstanding character of the embryo, namely this, that the cotyledons are so deeply cleft into 

 three lobes as to seem like six cotyledons. As soon as it was established that the embryo in the 

 isotype material of Navarretia mitracarpa had also this remarkable character of deeply cleft 

 cotyledons, then the prostrate plants of Lake County, referred to above, were not merely excluded 

 on thus being uncovered, they became at once fugitives from Navarretia mitracarpa. Nameless, 

 they have been named Navarretia jepsonii V. Bailey. Their cotyledons are entire.
