Nama Jamaicensis, ( LinnJ ): hispido-hirsuta; caule decumbente; foliis lanceolato-spathulatis 
in petiolura decurrentibus; floribus subgeminis axillaribus pedicellatis ; corolla campanulato- 
infundibuliformi calyce duplo-longiore; sepalis angusto-linearibus. Gravelly hills near the 
Great Colorado ; February 17. Also found near Fort Yuma by Major G. H. Thomas and Lieu¬ 
tenant Du Barry. It is a common species in the valley of the Rio Grande. We refer it to N. 
Jamaicensis with much doubt. 
Romanzoffia Sitchensis, Cham, in Linncea. 2, p. 609; Bong. Veg. Sitcli. t. 4. Redwoods, 
California ; April 12. It is interesting to meet with this species in California, where doubtless 
it is confined to the mountains. Dr. Bigelow’s beautiful specimens accord very well with those 
we possess from Sitcha, from Mertens’ collection. The calyx is glabrous. Choisy, (in DC, 
Prodr. 10, p. 135,) who had not seen the plant, has written “ calycis hirsuti,” doubtless by a 
slip of the pen, in place of glaberrimi , the word used by Chamisso. 
Hydrophyllum capitatum, Dougl. in Benth. Hydrophyll.; DC. Prodr. 9, p. 289. Hill-sides, 
Duffield’s Ranch, Sierra Nevada ; May. The peduncles are longer than usual, and the leaves 
are as large as in H. macrophyllum ; but the segments are sparingly incised, not coarsely 
toothed, and the lobes of the corolla have a pubescent line along the back. Perhaps the eastern 
and western plants may be united. 
Nemophila parviflora, Bentli. 1. c. With the preceding, and near Oakland, California; April. 
Nemophila atomaria, Fisch. & Meyer; DC. 1. c. Borders of fields, Corte Madera ; April. 
Nemophila maculata, Hartw.; Lindl. in Jour. Hort. Soc. 3, p. 319. Hill-sides, Duffield’s 
Ranch, Sierra Nevada ; May. A handsome species, now often seen in cultivation. 
Nemophila aurita, Lindl. Bot. Beg. t. 1601. Banks of the Stanislaus, at Robinson’s Ferry ; 
May. 
Nemophila insights, Benth. 1. c. N. li.niflora, Fisch. & Meyer, Hort. Petr op. Cajon Pass ; 
March. 
Phacelia tanacetifolia, Benth. Hydrophyll. 1. c. Los Angeles, San Francisco, etc.; March, 
April. Various forms. 
Phacelia circinata, Jacq. Eel. 1. t. 91; Benth. 1. c. Iiill-sides at Murphy’s, and in many 
other places in California ; May. 
Phacelia ciliata, Benth. 1. c. Los Angeles, and on the Great Colorado ; February, March. 
Eutoca hivaricata, Benth. 1. c. Near the Redwoods of California ; April. 
POLEMONIACE2E. 
Phlox occidentalis (Durand, Mss.) : glanduloso-puberula ; caulibus adscendentibus (subpe- 
dalibus) ; foliis lanceolatis rigidulis mucronatis ; pedunculis erectis brevibus ; calyce viscido 
corollas tubo paullo breviore, dentibus subulatis erectis tubo asquilongis ; corollas (albas ?) lobis 
late obcordatis contiguis ; ovarii loculis uniovulatis. P. divaricata, Durand , PI. Pratten in 
Journ. Acad. Philad. n. ser. 1855. Hill-sides, near Duflfield’s Ranch, May. Lower leaves not 
seen ; the upper 12-16 lines long, 2 or 3 wide, usually broadest at the base. Limb of the corolla 
an inch in diameter, the broad and rounded rather deeply obcordate lobes overlapping each other, 
not widely separate as in P. divaricata (in which, however, the lobes vary from strongly obcor- 
date-notched to barely retuse). Ovules solitary. Root doubtless perennial. The only species 
of the first section of the genus known west of the Rocky Mountains. 
Collomia gracilis, Benth. in Bot. Beg., & in DC. Prodr. 8, p. 308. Corte Madera and 
Sonoma ; April, May. 
Collomia glutinosa, Benth. 1. c. Sonora, California, along rivulets and ravines; May. A 
form with the corolla longer than usual; its slender tube half an inch long, and thrice the 
length of the calyx. 
Navarretia heterophylla, Benth. in DC. 1. c. Collomia heterophylla, Hoolc. Mokelumne 
Hill, and Grass Valley, California ; May.
