524 DESCRIPTIONS AND NOTES FROM THE BOTANICAL GAZETTE. 
Some ADDITIONS TO THE NoRTH AMERICAN FLORA. 
DICENTRA OCHROLEUCA, n. sp. Stem erect, 3-4 feet high, leafy, leaves glaucous, large (lower ones a foot [223] 
or more long), 3-pinnate, ultimate divisions deeply cleft into lanceolate-linear lobes ; flowers panicled on very 
short pedicels, about 15 lines long, ochroleucous ; membranaceous sepals suborbicular ; exterior petals slightly saccate 
at base, upwards narrower, somewhat concave below the acute tip, and scarcely spreading ; inner petals widened above 
into a deep purple circular tip, crested with two very broad flat and elongated appendages ; stamens subulate scarcely 
cohering. 
In valleys of the Santa Monica Mountains near Los Angeles, Cal., where it grows with the rather rare Ceanothus 
spinosus, the rootstock of which, named red-wood, furnishes the principal firewood there. — Together with D. chrysan- 
tha this handsome species constitutes the subgenus Chrysocapnos, in which the crest, single and inflated in the true 
Dicentre, is formed of two distinct lamella, flat and Jarge in our species, short and curly in D. chrysantha. This 
latter is a coarser plant with much smaller golden yellow flowers (6-9 lines long) and deeply concave, spreading outer 
petals.

Escuscuoirzia Cattrornica. The different forms of this common and extremely variable plant deserve [235] 
to be studied more carefully at their homes, where they are found in such untold abundance. It is quite possi- 
ble, as indicated in the Flora of California, that the several species into which it had been divided, may be sustained 
by reliable characters. All the forms, however, are said to be annuals with colorless juice. Now, on the sandhills of 
the ocean, quite close to the well-known Cliff-house near San Francisco, I found last October a form with long peren- 
nial roots, } inch thick, abounding in orange-colored juice, and bearing several stems ; leaves shorter than the inter- 
nodes, often opposite, flowers 1 inch wide ; torus broadly margined, capsule about 2 inches long, seeds reticu- 
lated. In most respects it represents the typical form of EL. Californica, but the perennial ‘rootstock seems to [236] 
distinguish it ; annuals, to be sure, in mild climates not rarely last for several years, e. g. Solanwm nigrum in 
Southern California, but in these the stem becomes ligneous and no rootstock forms, the normal tap-root not losing its 
characters, even if it does become 3 or 4 years old. It is barely possible that EZ. Cadifornica is one of those perennials 
which will flower as seedlings in the first years, and that then the aridity of the climate in many instances kills it, root 
and all; but if so, why has this mate (2) perennial character not been observed before ? 
PORTULACA SUFFRUTESCENS, . — Erect, about a span high from a stout, branching and apparently perennial 
rootstock, ligneous at base; leaves Sorel 5 a 1 inch long, with sparingly hairy axils ; flowers clustered at the end 
of the branches, large (7 to 10 lines wide), yellowish buff-colored ; petals “beaNiats or emarginate ; stamens numer- 
ous ; filaments, like the 5 or 6 stigmas, red ; seeds dark, with metallic lustre, tuberculate. 
In W New Mexico, at the copper mines, C. Wright, 874, coll. 1851; Cowes & Palmer, Fort Whipple, 
Northern Arizona, 1865; found by myself, 1880, on rocky banks in the Santa Rita Monetaitis, Southern Arizona. 
ery near P. pilose, with which I had formerly united it ; the seeds of both are similar, their tubercles, magni- 
fied 40-60 diameters, appear very prettily as overlapping excrescences with a toothed free edge ; both have dark seeds, 
ours with a metallic lustre, the others more dull. The number of stamens in different flowers was about 40 ; while in 
P. pilosa it is stated to be 15 to 25, but in cultivated specimens of the latter I have found as many as 50! The color 
and size of the flower, the larger leaves with sparing hair in the axils, and the stouter stems and perennial (?) rootstock 
distinguish it from its purple-flowered annual relative. 
Rosa spITHAMEA, Watson, FI. Cal. 2, 444. —In the deep shade of the Big Trees of Fresno County, Cal., where 
searcely + deep else grows, I found what I take to be a form of this pretty little species, blooming in September, I 
may designate it 
Var. SUBINERMIS : stems a s span high, glabrous or more or less glandular hispid, with a few scattered setaceous 
spines (none stipular) or spineless ; stipules skert and narrow with short narrow divaricate free points ; leaflets mostly 
5, thin, pale below, elliptical or nearly orbicular, obtuse, sharply serrate and glandular serrulate; rhachis glandular- 
pubescent and often spinulose, petiolule of terminal leaflet almost its own length ; flowers single (1} to 14 inches wide) 
rose-colored ; peduncle slightly glandular, calyx tube globose, naked, lobes entire. 
The stems of the same season bear the flowers, us is the case in R. foliolosa of Texas; or is it in this instance an 
autumnal form ? There may be characters enough, especially the absence of any stipular spines, to distinguish speci- 
fically this southern form from the northern type, but considering the great variability of roses it is thought best to 
keep them together for the present. 
The western roses, and to some extent all our roses, are in some confusion and what my cursory visit to [237] 
the Pacific coast may have done to clear them up is offered here.
