286 PITTONIA. 
greenish yellow, segments erect: stamens nearly equalling 
the corolla; anthers small, orbieular.— E. lanceolata of page 
264 preceding. 
Probably common on the Lower Californian islands and 
shores. ‘The description is drawn from Lieut. Pond's San 
Benito specimen, now in flower. The anthers of C. lanceolata 
are linear-oblong, and its filaments are much shorter; but 
the difference in form of leaves, ete., is very considerable. 
SAXIFRAGA CaLIFORNICA. Perennial, fibrous-rooted and 
propagating by small oblong tubers produced at the ends of 
filiform subterranean branches : stem scapiform, 6—18 inches 
high, bearing a loose cymose panicle of bracteolate and few- 
flowered racemes: leaves oval, oblong or elliptical, an inch 
or two long, on broad petioles half as long, the margin from- 
coarsely crenate to somewhat repandly denticulate, or almost 
entire, both surfaces more or less pubescent and the margin 
ciliolate-tomentose: calyx free from all but the base of the 
ovary, the sepals reflexed : petals white, narrowly elliptical 
or a little spatulate below, 14 lines long, obtuse at apex: 
stamens 10; filaments filiform or flattened; anthers roundish, 
dark-red : styles erect and approximate in flower, carpels at 
length divergent.—S. Virginiensis, Boland, Catal. 11; Brew. 
& Wats. Bot. Calif. i. 194, not of Linn. 
Very common in the central parts of California, in the 
Coast Range especially. It was latterly referred by Dr. Gray 
to S. reflexa, Hook., but apart from the reflexed sepals it is 
more like S. Virginiensis. It is, however, quite distinct from 
both; and its propagation by tubers has hitherto remained 
unnoticed. These are scarcely to be observed in the most 
carefully preserved herbarium specimens, because of the 
delicacy and fragility of the subterranean branches which 
bear them. In the fresh flower the summit of the ovary 
appears as if very broad and flat; but this is owing to the 
presence of a partly epigynous nectariferous disk the margin 
of which coheres with the calyx and touches the base of the 
filaments. The floral structure in S. reflexa is not in the
