294 PITTONIA. 
PHacELIA ARTHURI. Annual, diffuse, the stoutish branches 
2 feet long or more: herbage not viscid, setose-pubescent, 
the inflorescence hispidulous : leaves loosely pinnate, or some 
lyrate, the lobes crenate-toothed : spikes numerous, solitary 
in the leaf-axils, and very short-peduncled: flowers crowded 
and biserial: ealyx-lobes entire, very unequal, four of them 
small and at length partly enfolded by the accrescent rhombic- 
obovate aeute outer one: corolla very small, open-campanu- 
late, about a line and a half broad, light blue: stamens not 
exserted. 
Discovered growing in a by-street toward the western part 
of the eity of Oakland, in 1887, by my former pupil, Mr. 
Arthur B. Simonds. The capsule and seeds are unknown; 
for the plant appears to have been sterile. It is nevertheless 
pretty clearly of the Euphacelia section of the genus ; doubt- 
less indigenous, and a local plant singularly preserved in the. 
midst of a city, where it is now on the verge of extinction. 
Strangest of all is the fact that it is a very near relative of P. 
scabrella (Pittonia, i. 35), which is endemic on a small island 
two hundred miles or more down the coast. In that species I 
had noted an inequality in the sepals. It is a good deal more 
pronounced in the present plant, where the enlarged outer 
ones lie imbricated over one another up and down either side 
of the spike iu such a way that one at first will be liable to _ 
mistake them for bracts. 
. Rises Vicrorts. A somewhat slender spinescent shrub, 
5 feet high, younger branches very prickly, young growing 
parts puberulent and somewhat viscid: leaves an inch broad, 
3 to 5-lobed, on slender petioles subtended by not very stout 
triple spines: pedicels with 1 or 2 persistent entire bracts 
and as many large nodding greenish white flowers: calyx-_ 
lobes linear-oblong, recurved: petals acutish at apex, and 
erose-toothed : filaments not exceeding the petals; anthers 
ovate-oblong, broad but not sagittate at base, obtusish at 
apex but not mucronate: ovary glandular-hirsute : fruit 
unknown.
