144 POLEMONIACEAE 



Leptodactylon calif omieum is distributed nearly throughout the coastal phytogeographic area 

 from San Luis Obispo Co. to Orange Co. and western Riverside Co. It is of especial interest that 

 on no one of the Santa Barbara Islands has it as yet been discovered — or at least recorded. It has 

 been attributed to Monterey (Bot. Cal. 1:492) and may yet be found in southern Monterey Co.

4. NAVARRETIA K & P. 



Small annuals with mostly rigid stems. Leaves alternate, once or twice piu- 

 nately divided or piunatifid or the lowest sometimes entire or subeutire, the seg- 

 ments mostly rigid, subulate to lanceolate or acicular, cuspidate or spinose. Lobes 

 or teeth of bracts and calyx spiny or cuspidate. Calyx not accrescent, its teeth or 

 lobes mostly unequal, tootlied or spiny or entire, its tube scarious between the 5 

 angles or ribs. Corolla tubular-funnelform or salverform, blue, white or yellow. 

 Stamens exserted or included, the filaments mserted in the corolla-throat; anthers 

 oval (oblong in N. viscidula). Capsule commonly 3-celled and 3-valved, or in a 

 few species 1-eelled and 4-valved, or circumscissile or indehiscent. — Species 34 in 

 western North America, 1 in South America. (Fr. Ferd. Navarrete, a Spanish 

 physician.) 



Flower and fruit in Navarretia. — All the species of Navarretia exhibit a marked similarity 

 of habit, foliage, inflorescence and flowers, so much so that many species, as here set down, are 

 difficult, in the absence of constant technical characters, to recognize unless in their most marked 

 phases. 



Several species, however, show strong departures in flower and fruit characters from the main 

 generic pattern or even from the prevailing ordinal character. In Navarretia cotulaefolia and 

 N. bowmanae the flower is usually 4-merou3, instead of 5-merous as prevailing in the family 

 generally. In Navarretia cotulaefolia the style has 2 stigmas and the ovary is 2-celled with a single 

 ovule in each cell. During development one ovule is crowded upwards so that the two ovules do 

 not lie side by side, but somewhat obliquely. As the capsule grows the partition disappears and 

 the 1-celled capsule usually contains only one seed. Since the ovary is 2-celled a 2-valved capsule 

 would be expected, but each valve splits along the median line from below making four valves. 

 Such 4-valved capsules characterize also Navarretia pubescens, N. mitracarpa and N. filieaulis, 

 whereas the capsule is 3-valved in the family generally. In Navarretia nigellaeformis, N. bow- 

 manae, N. pubescens and N. jepsonii the capsule is 1-celled or usually so, or sometimes imper- 

 fectly 2-celled. Yet again, in Navarretia intertexta, N. leucocephala and N. prostrata the capsule 

 is indehiscent (with the seeds agglutinated in a mass) or with the thin walls breaking down irregu- 

 larly. In Navarretia setiloba the capsule is circumscissile. The style, typically 3-cleft, is in some 

 species 2-cleft as in Navarretia intertexta and N. setiloba, or quite entire as usually in Navarretia 

 leucocephala, N. minima and N. filieaulis. 



A remarkable peculiarity sometimes characterizes the embryo. While investigating embryos 

 in Polemoniaceae in 1896 the writer discovered that the embryo in Navarretia pubescens is fur- 

 nished with apparently six cotyledons instead of two. In reality there are two, each so deeply 

 cleft into 3 loljes as to appear Uke 3 cotyledons, although in one instance (Calistoga, Beardsley) 

 the embryo showed 3 cotyledons, each 2-cleft. The peculiar 3-divided cotyledons were described 

 in this author's Flora of Western Middle California (1901), a description cited by A. Brand in 

 connection with further accounts of the matter in Engler's Botanische Jahrbiieher (36:77, — 

 1905). Since that time similar cotyledons (deeply cleft into 3 lobes) have been demonstrated in 

 the embryo of Navarretia mitracarpa. The embryo in Navarretia setiloba is also very unusual. 

 It has 3 cotyledons which are slightly unequal and so deeply cleft as to give somewhat the appear- 

 ance of 6 cotyledons. 



Toothing of leaf-segments or character of the segments are features reflected sometimes in
