ALNUS OBLONGIFOLIA Torr. 



Alnus rhombifolia Nuttall. 



The alder is a slender tree occurring 

 along our perennial streams, from Mis- 

 sion valley to the Cuyamaca mountains 

 in Lower California, and north and 

 eastward. Rarely exceeds 50 feet in 

 height and 2 feet in diameter. 



ER1OGONUM FASTIGIATUM Parry. 

 "Fruticose, 3-6 inches high, fastigiately 

 branched from near the base and dicho- 

 tumous above, the younger stems densely 

 la nose; leaves crowded below, more scat- 

 tered ajbove, linear lanceolate, 3-5 mm in 

 length, loosely hairy above, densely to- 

 mentose beneath, strongly revolute, ta- 

 pering below into a slender petiole with 

 a broad membranous clasping base; invo- 

 lucres sessile in the upper axils, or ter- 

 minal on the dichotomous branches, 2 

 mm in height, deeply 5-parted, with acu- 

 minate segments, united below into a 

 membranous tube; perianth with broadly 

 oval segments nearly equal, with short 

 turbinate tube; bractioles linear-hispid 

 shorter than pedicels; stamens 9, anthers 

 reddish, akenes narrowly winged, embrio 

 not seen. A low, densely branched shrub, 

 its slender fastigiate branches forming a 

 flattened summit, with the remains of 

 dead foliage below, flowers rather con- 

 spicuous, intermixed with the projecting 

 dichotomous branches. To be placed in 

 the virgate section though the inflores- 

 cence is mainly reduced to a single ter- 

 minal involucre. Is apparently near B.

MICROSERIS PLATYCARPHA A. Gray. 

 Span or more high, head %' or less in 

 length; main bracts of involucre about 8, 

 oblong; akenes turbinate, 2" long, taper- 

 ing abruptly into a very, short awn. San 

 Diego county, Cal., southward. 



PHACELIA LYONI A. Gray. 



Viscid'-pubescent and heavy-scented, a 

 fot or more high, robust: leaves pin- 

 nately divided into narrow oblong and 

 deeply pinnatified divisions; their short 

 lobes oval and crenate: spikes dense: 

 corolla (pale or ochroleucous) 2 or 3 lines 

 long, broadly campanulate; appendages 

 semi-oval, their base united to the fila- 

 ment: stamens and style not exserted: 

 capsule narrowly oblong, many-seeded, 

 nearly equalling the linear-spatulate 

 hispid and viscid sep: seeds oval, scro- 

 biculate. Cat (Nevin & Lyon). 



PHACELIA ORCUTTIANA A. Gray. 



Viscid, pubescent, about a foot high: 

 leaves pinnatified, somewhat lyrate, the 

 lobes short-oblong and entire: fls sessile 

 in the at length elongated dense spikes: 

 ccrolla ro-tate-campa-nulate, double the 

 length of the calyx, with limb 3 or 4 lines 

 broadi, white with yellow eye, nearly or 

 quite destitute of internal appendages: 

 capsule oval, nearly equalling the nar- 

 rowly spatulate (barely 2 lines long) sep- 

 pals, 12-14-seeded : seeds oval, obscurely

 PHACELIAi PARISHII A. Gray. 



Very like P. pulchella in foliage and 

 habit: peduncles fully as long as the 

 fruiting spike, primary ones scape-like: 

 fls almost sessile, crowded: corolla (2 

 lines long) blue or bluish, hardly at all 

 surpassing the calyx, the appendages ob- 

 scure or none: fructiferous sepals broad- 

 ly spatulate, equalling the oblong about 

 20-seeded capsule: seeds over l / 2 line in 

 length, narrowly oblong, scrobiculate.

 PHACELIA SUFFRUTESCENS Parry. 



"Plant decumbent, branching from a 

 perennial root, with occasional suffru- 

 tescent stems persistent for several 

 years; hispid pubescent throughout, the 

 setose-hispid hairs intermixed with short- 

 er stalkedl glands containing an amber- 

 co'ored, viscid, oily secretion; lower 

 Ivs interruptedly pinnate, pinules 5-7, 

 sessile, ovate, pinnatifid-incised or lobed; 

 fl'ng branches divaricate from the axils 

 of the upper leaves, rather short, with 

 close spikes; fls shortly pedunculate, se- 

 pals spathulate, about twice the length 

 of the capsule; corolla inconspicuous, lit- 

 tle exceeding the calyx, short, funnel- 

 form, lobes shorter than the tube; appen- 

 dages oblong, obliquely truncate above, 

 nearly as long as the tube, slightly 

 broader, but not auriculate or hooded, be- 

 low; stamens moderately exserted; style 

 long, divided nearly to the base; ovary 

 short-oval, hispid-pubescent, quite con-

 NEMOPHILA AURITA Lindl. 



Plant prickly, weak and straggling, 

 leaning on other plants for support: 

 branches 2-6i dm long, hirsute, angled or 

 winged, the angles armed with sharp 

 prickles which aid in climbing: leaves all 

 but the lower alternate, 5-15 cm long, 

 more or less deeply pinnatifid into mostly 

 7-13 entire or shallowly lobed downward- 

 pointing divisions; retrorsely barbed 

 along the principal veins beneath; pet- 

 ioles winged, expanded below into an au- 

 rieulate-clasping base: fls mostly in very 

 loose naked racemes at tips of branches: 

 calyx-lobes lanceolate, 4-10 mm long; ap- 

 perdages usually less than a third as 

 long, spreading: corolla with a short 

 throat constricted below the top and 

 spreading limb 1-3 cm across, violet, paler 

 outside: scales triangular, usually fim- 

 briate. below covering base of the sta- 

 mens, above turning away from them, 

 often 3 mm long: nectaries prominent. 1

 times as long as ovary, cleft only at tip: 

 capsule globular, 5-9 mm in diam., thin 

 v, ailed: seeds 4 per capsule, globular, 1.25-
