14. D. DENSIFOLIA. Probably dwarf, all the branches short, 
stoutish, densely leafy with foliage ascending and imbricated 
on young shoots, less so on those older and floriferous: leaves 
of only subcoriaceous texture and decidedly glaucous, of oblan- 
ceolate-elliptic outline, or a few quite elliptic, obtusish, muero- 
nate, a narrow and thinnish margin more or less revolute and 
crisped but not denticulate, the whole 1 or 2 inches long, finely 
feather-veined and reticulate, the reticulation not at all pro- 
nounced, rather faint, low, perfectly smooth: peduncles ex- 
tremely short, not equalling the leaves even in fruit: pod barely 
12 inches long. 
Known to me only as collected on Santa Rosa Island in 1388 
by Mr. Brandegee, reckoned by him to be what he would call 
var. Harfordii of D. rigida, but, as I have intimated above, not 
at all related to D. Harfordii, only imitating that in habit. 
The foliage here is remarkably thin, recalling that of some 
ericaceous shrubs. 
15. D. FLexinis, Greene, Bull. Torr. Club. xiii. 216. D. 
Harfordii, Kell. l. c. in small part. Arborescent, 6 to 20 feet 
high, not rigid, the branches often drooping with the heavy 
weight of a dense mass of coriaceous foliage: leaves of mature 
branches typically oblong-obovate, about 2 inches long, obtuse 
or acutish, mucronate, perfectly entire, strongly glaucous on 
both faces as well as finel y and closely feather-veined, but with no 
trace of reticulation, the texture strongly coriaceous but pliable, 
not rigid; leaves of vigorous young shoots broadly oblong- 
elliptic, some more than 5 inches long and 3 in width, no foli- 
age erect or even ascending, usually widely spreading : peduncles 
numerous, axillary, short, never equalling the leaves: corolla 
2 inches wide: pods usually 3 inches long: seed spherical, very 
finely reticulate, not large, the caruncle apparently entire an 
cup-shaped. 
Ten years before my own discovery of this most remarkable 
papaveraceous tree on Santa Cruz Island, Dr. Rothrock had 
brought a branch of it from the same island; this now pre-
