PREFACE
The author is very grateful to the following contributors : Roxana Stinchfield
Ferris for the family Euphorbiaceae, except for the genus Euphorbia whicii was con-
tributed by Louis Cutter Wheeler, and for the text of Hackelia in the Boraginaceae ;
Ira Loren Wiggins for the families Malvaceae, Cactaceae, except for the genus
Opuntia which he contributed jointly with Carl Brandt Wolf, and the Solanaceae;
George Neville Jones for the family Hypericaceae ; Philip Alexander Munz for the
family Onagraceae; Mildred Esther Mathias and Lincoln Constance for the family
Umbelliferae ; Rimo Bacigalupi for the family Garryaceae ; Herbert Louis Mason for
the family Polemoniaceae, except for the genus P olemonium which was contributed
by John Eraser Davidson and for the genus Gilia which was contributed jointly by
Herbert Louis Mason and Alva Day Grant ; Lincoln Constance for the family Hydro-
phyllaceae ; and Erancis Whittier Pennell for the family Scrophulariaceae, except for
the genera Orthocarpus and Penstemon which were written by David Daniels Keck.
The text of the remaining famihes was written by the author. Ira Loren Wiggins
has given much assistance in solving the nomenclatorial and taxonomic problems.
Roxana S. Eerris has selected the material for the original illustrations and, together
with Sylvia Vincent and Barbara Law, has done the necessary editorial work of
checking references and reading manuscript and proof.
As in Volume I the illustrations are original except those which were used from
Britton and Brown's Illustrated Flora of the Northern United States and Canada.
The use of these illustrations is gratefully acknowledged to the New York Botanical
Garden. The original drawings are, for the most part, the work of Jeanne Russell
Janish. The drawings for the Onagraceae and Polemoniaceae were, in part, made at
Pomona College and the University of California, respectively. A number of drawings
scattered throughout the various plant families have been made by William S. Atkin-
son, Alice Baldwin Addicott, Louise Nash, and Lawrence Beane.

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,

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.

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.

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,

recognition for albinism occurs throughout the genus, but the short, broad, glandular-puberulent capsule is dis-
tinctive. 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

Phlox Family.
Annual or perennial herbs or shrubs or vines. Leaves simple or palmately cleft
or pinnately incised, lobed or dissected, or compound, sometimes pungent or entirely
bracteate, opposite or alternate. Inflorescence usually a paniculate, glomerate, or
flat-topped cyme, or the flowers congested in densely bracteate heads, rarely solitary,
with flowers with 5-merous, rarely 4- or 6-merous perianth and androecium, the
gynoecium typically 3-merous. Calyx herbaceous to variously membranous or
chartaceous, accrescent or sometimes distended or ruptvired by the growing capsule ;
variously cleft to the herbaceous tube (herein called the tube proper), or cleft to
the base, the lobes free or more commonly the membranes of their margins coalesced
to form a tube of varying length (herein called the pseudotube) superimposed above
the tube proper, or the tube proper absent and only the pseudotube present. Corolla
sympetalous, campanulate to funnelform or salverform, the tube from nearly
obsolete to 3-6 cm. long; throat usually evident, exceeding or shorter than tube
and herein said to be ample when its sides form an angle of more than 60 degrees
with one another and narrow when they form an angle of less than 60 degrees.
Stamens equally or unequally inserted on the corolla, their filaments equal or
unequal. Ovary 3-celled, rarely 2- or 1 -celled, style simple, stigma-lobes usually
3, rarely 2, 4, or 1. Fruit a capsule, usually regularly dehiscent, rarely indehiscent.

Family 129. FOUQUIERlACEAE.
FouQuiERiA Family.
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.

LENNOA FAMILY 475
Family 130. LENNOACEAE.
Lennoa Family.
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.

regular, narrowly funnel form, with 5-7, rounded, prickly imbricate lobes. Stamens as
many as the corolla-lobes, and adnate to above the middle of the corolla-tube. Ovary
subglobose, 6-10-celled with each cell divided into two by a dorsal false partition. Stigma
crenately 6-10-lobed. Fruit subglobose, remaining within the persistent corolla, very
tardily breaking up. [Name Greek, meaning scale, referring to the scale-like leaves on
the stem.]

high, sparsely bristly otherwise usually glabrous except for a tomentose pubescence near the
base of the spikes. Basal and lower cauline leaves linear or linear-lanceolate, the upper lanceo-
late to broadly so, usually clasping at base and acute at apex, thinly hirsute on both sides
with spreading, often pustulate hairs; spikes short or usually elongated in fruit, usually leafy-
bracted at base; calyx-lobes linear-attenuate, about half as long as the corolla, rufous-hispid
on the back, densely" white-hirsute on the margins; corolla orange-yellow, 8-10 mm. long, the
limb 3-6 mm. wide; nutlets 2.5-3 mm. long, incurved, grayish, narrowly keeled on the back

An extremely variable species of wide geographic range. Suksdorf (Werdenda 1: 48-113. 1931) in a study
of the genus has proposed many new species, a large number of which belong to this complex, but extensive
cytogenetic studies are needed before the biological significance of these variations can be determined. In the
desert regions strongly pustulate forms which sometimes have been referred to Amstnckta echtnata A. dray
suggest hybridization between Amsinckia intermedia and Amsinckia tessellata.

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.
