300 PITTONIA 
Known only from the Santa Inez Mountains behind Santa 
Barbara, by G. W. Dunn, 22 May, 1891; type in erb. 
Most like Æ. rigida in leaf-outline, but in that one particular 
only; unlike it in other important characters. 
6. D. SALIGNA. Leaves narrowly oblong-lanceolate, 2 to 34 
inches long, abruptly and pungently acuminate, obscurely or 
not at all denticulate, hard and rigid, indistinctly and flexuously 
feather-veined, but veins and yeinlets breaking into an irregular 
and smooth reticulation: corolla 2 inches wide: pods 24 inches 
long: seeds round-pyriform, marked with an unusually coarse 
favose reticulation. 
Encenitas, California, T. S. Brandegee; type in U. S. Herb., 
where, by the way, Mrs. Brandegee has attributed the specimens 
to Lower California. Mr. Brandegee (Zoe. i. 47) reports that 
this is a shrub six to ten feet high, with much the habit of 
D. flexilis; and perhaps its real affinities may lie with some 
insular species, but if so, with D. arborea rather than with 
D. flexilis. : 
7. D. ELLIPTICA. Evidently a larger, more luxuriant and 
leafy shrub than D rigida and wanting its yellow-green hue, 
pale and very glaucous, also less rigid: leaves mostly exactly 
elliptical, 2 or 23 inches long, mucronate-acute, closely and 
finely denticulate ; reticulation distinct but little elevated, 
smooth as to the upper face, sparingly muriculate scabrous as 
to the lower: corolla little more than an inch wide: pods 4 
inches long, marked by uncommonly strong ribs and alternating 
furrows: seed small; nearly spherical, marked with a slightly 
elongated minute enue running somewhat in lines. 
Common in mountain districts of all southeastern Cali- 
fornia, from the yalley of the Kaweah, Coville & Funston, and 
middle Tule River, Purpus, to Waterman Cañon, San Ber- 
nardino Mountains, Parish, and the Lower California boundary 
at Campo, San Diego Co., Calif., G. R. Vasey; all these speci- 
mens typical, as in U. S. He rb.
