(Fremontia napensis Eastw. Leaflets West. Bot. 1: 140. 1934.) Shrub, often spreading from the base, 2-3 m. high, young twigs of the season densely stellate-pubescent with very short-rayed stellate hairs, the older portion of the branchlets glabrous and reddish brown. Leaves 1-2 cm., rarely 2.5 cm. long, entire to shallowly 3-5-Iobed, obtuse or rounded at base, rather dark green above with scattering short-rayed stellate hairs, pale green and densely stellate beneath, the pubescence whitish at first, becoming ferruginous in age; calyx yellow or often tinged with rose, small, the sepals commonly only 1-1.5 cm. long. Chaparral-covered slopes, Upper Sonoran Zone- Coast Ranges of southern Lake County and adjacent Napa County, California. Type locality: north side of Mount Saint Helena, Napa County. Small-flowered plants usually with smaller subentire leaves occur almost throughout the range of the species, but none of these seems as extreme in its variations as the plants from the Mount Saint Helena region. Margaret Harvey (Madroiio 7: 100-110. 1943) has made critical herbarium studies of Fremontia and recognizes 5 species: F. californica Torr., F. napensis Eastw., F. crassifolia Eastw., F. obispoensis Eastw., and F. mexicana (Davidson) J. F. MacBride. Under F. caltformca she also recognizes 4 varieties, which she distinguishes as follows: Leaves variously lobed: (a) leaves dull green or dark green above, pubescence decidedly tawny below and often matted, variety typica (Shasta County to San Diego County); (6) leaves bright green above, pubescence whitish below, not tawny, variety viridis (Tehama County). Leaves entire, dull green or dark green above, pubescence of lower surface becoming tawny: (c) petioles short, one-half to one-third the length of the blade, variety integra (Tulare and Kern Counties); id) petioles longer than one-half the length of the blade, variety diegensts (San Diego County). As the typical form of the species seems to occur throughout the range, the biological significance of these variations is not clear. Much more study, especially in the field, must be given before the constancy of the characters noted can be determined. ST. JOHN'S-WORT FAMILY 115 2. Fremontia mexicana (Davidson) J. F, Macbride.

Leaves obovate to oblong-oblanceolate, rounded to acutish at apex, narrowed to a distinct petiole about equaling the blade, 5-10 cm. long including the petiole, 1-25 cm. wide ; scapes rather stout, 10- 20 cm. high; flowers 1-3, rarely more in the umbel, 5-merous; corolla deep purple varying to rose-purple or rarely white, tinged with yellow at the base of the lobes, these 15-20 mm. long; anthers sessile, distinct, 6 mm. long, dark purple ; capsule cylindric, 8-12 mm. long, circumscissile below the apex then splitting into valves ; seeds broadly ellipsoid, slightly flattened, brown. Moist slopes and thickets, Arid Transition Zone; Chelan County, Washington, to Lassen County, California, and Steen Mountains, southeastern Oregon, east to Montana and Wyoming. Type locality: "My first specimens were from Prof. Kelsey, who obtained them on dry hills near Helena, Montana. Better material is now in hand collected in southeastern Oregon, in 1893, by Mrs. R. M. Austin." It is obvious from this statement that Mrs. Austin's specimen is the type and therefore the type locality is "southeastern Oregon." March-May. Dodecatheon conjugens var. viscidum (Piper) H. L. Mason ex St. John, Fl. S.E. Wash. 311. 1937. CD. viscidum Piper, Bull. Torrey Club 28: 43. 1901.) Whole plant, including calyx and capsule, glandular- puberulent; capsule cylindric, narrow, 10-15 mm. long, circumscissile near the apex. In describing this species Professor Piper wrote: "collected by the writer ten miles west of Spangle, Wash. 24 May 1898. The plant was found on a grassy hillside in one spot only, and is apparently very rare." Subsequent collections have been made bv Suksdorf on "damp low ground near Spangle." These specimens are dated April 26, May 17, and June 30, 1916. 5. Dodecatheon Cusickii Greene. Columbia or Sticky Shooting Star. Fig. 3767. Dodecatheon Meadia var. puberula Nutt. Journ. Acad.

Unfortunately the original collection is the only material I have seen. Field studies are greatly needed of this plant and of D. conjugens var. viscidum (Piper) H. L. Mason of the same region. It is possible that the two entities are h\brids between D. Cusickii and D. conjugens. Type locality: damp or dry, mostly rocky places near Spangle, Spokane County, Washington. 6.

Spiny branched shrubs or small trees, or in Idria with a simple columnar trunk. Leaves alternate on the end of elongated petioles that soon develop into stout spines, secondary leaves fascicled in the axils of the spines. Flowers showy, in terminal panicles. Sepals 5, imbricated, persistent. Corolla sympetalous, tubular, 5-lobed. Stamens 10-15, attached to the base of the corolla-tube ; filaments thickened at base. Ovary solitary, imperfectly 3-celled by the protruding placentae. Ovules few, usu- ally 3-6. Fruit a 3-valved capsule. Seeds winged or the angles fringed with hairs. A unique family comprising 2 closely related genera, the following and Idria with one species, Idria colum- naris Kell. of Lower California. The botanical relationship of the family is not clear. In the Botany of California Sereno Watson (1876) placed the genus Fouquieria in the family Tamaricaceae with this comment: "Its char- acters are anomalous, and it has been placed by different authorities in the orders [families] Polemoniaceae, fia)ikcniactac. t oi iviacaccue, and Lrassuiaccae, and taken for a distinct order Fouquieraceae." At the present time it is generally accepted as a distinct family, some authors placing it in the choripetalous order Parietales near the 1 atnaricaccae and others (Diels, in Engler's Syllabus der Pflanzenfamilien, 1936) in the sympetalous order Tubifiorae near the families Convolvulaceae and Polemoniaceae. 1.

Fleshy brownish herbs without chlorophyll, parasitic on roots, leaves reduced to bract-like scales. Flowers perfect, in densely flowered spikes or heads. Calyx deeply parted into nearly distinct narrowly linear segments. Corolla sympetalous, tubular, the limb 5-8-lobed. Stamens as many as the lobes of the corolla, inserted on the throat alternating with the lobes ; anthers 2-celled, dehiscent by longitudinal slits. Pistil 1, composed of 6-14 completely united carpels; style 1, simple; stigma sub- capitate or peltate, crenate ; ovary divided by dorsal false partitions into twice as many cells as carpels with one ovule in each cell. Fruit a drupaceous capsule, tardily and irregularly circumscissile, breaking up into 12-28 nutlets. Seed with endosperm and a globular embryo not differentiated into caudicle and cotyledon. A genus of 3 genera and 5 species. Besides the following, the genus Lennoa, with 2 species inhabits Mexico. The Lennoaceae is an anomalous group of plants, often placed in the Ericales, but other than the Parasitic habit of the Monotropaceae, it has little or no morphological affinities with that group. Diels (Ivngler, byllabus der Pflanzenfamilien, 1936) has placed it in a suborder of the Tubiflorae, between the suborder Convo/rM/otdeae and the suborder Borraginineae. The character and position of the stamens would indicate that this is a more natural classification. Flowers in a dense terminal spike; sepals puberulent. 1- Phohsma. Flowers on a terminal peltate disk; sepals plumose. 2. Ammobroma. 1. PHOLISMA Nutt. ex Hook. Ic. PI. pi. 626. 1844. Fleshy parasitic herb with scale-like leaves.

March-July. X Salvia bemardina Parish ex Gieene, Bull. Calif. Acad. 1: 211. 1885. (Salvia Columbariae var. bernar- dina Jepson, Man. Fl. PI. Calif. 869. 1925.) As pointed out by Asa Gray (Syn. Fl. N. Amer. ed. 2. 2i : 460. 1886) and Munz (Man. S. Calif. 444. 1935) these plants are probably natural hybrids between Salvia Colum- bariae and S. mellifera. They flower as an annual, but some plants persist longer, the stems becoming lignescent; leaves once-pinnatifid; upper lip of calyx with 3 spine-like teeth. These apparently natural hybrids are found mainly in the San Bernardino Valley, southern California, and occur where the two supposed parents grow together. If future genetic studies bear out the conclusions of field observation, these hybrids offer one of the strongest arguments for uniting Bentham's genus Audtbertta with the genus Salvia. 4.
