78 Easrwoop: SOME NEW SPECIES OF CALIFORNIAN PLANTS 
line leaves few and distant, with large, obliquely ovate stipules 
which are adnate to the petiole up to the blade; these are similar 
in form to the leaflets but larger: cyme with 2-4 branches, each 
1—2-flowered: calyx clothed with appressed pubescence, more 
densely so at base; divisions ovate, obtuse, 6 mm. long, 3.5 mm. 
wide : bractlets % as long, ovate : petals yellow, 6 mm. long, 5 mm. 
wide, cordate with shallow sinus: receptacle white-hairy : filaments 
narrowly subulate, 2 mm. long: style slender, attached to the 
akene a little below the apex, glabrous, 3 mm. long: akene gla+ 
brous, gibbous. 
This seems to come nearest to Potentilla Plattensis Nutt., from 
which it differs in having larger flowers, with obtuse calyx lobes 
and bractlets and digitately cleft leaflets less imbricated. The 
_ broad stipules are noticeable on the cauline leaves, those on the 
radical leaves being much narrower. 
This was collected in a forest of Pinus radiata Don., near the 
reservoir which supplies Pacific Grove, California, along the road 
to Cypress Point, April 4, 1900. It is named in honor of Mr. J- 
B. Hickman who has collected many interesting plants in Monterey 
county and who was my guide on the trip on which this was col- 
lected.

Orthocarpus psittacinus 
Perennial, stems several frony a branched caudex, generally 
also branching above, i.5—2 dm. high, striate, pilose with spread- 
ing white hairs: lower leaves linear, entire, 2-6 cm. long; upper — 
ones broader, 3—5-cleft near the apex into linear lobes, the middle 
lobe longest ; floral leaves broader, the middle lobe generally ir- 
regularly 2—5-cleft, the ultimate division often broadening at the apex, 
greenish-yellow, surpassing the flowers: calyx with membranous 
tube enclosing the corolla and with four lanceolate-filiform divi- 
sions, equal or unequal, extending below to the ovary and above 
to the throat of the corolla, greenish-yellow: corolla the same 
color, 2 cm. long ; upper lip straight, slightly surpassing the lower, 
obtuse ; lower lip 3-cleft with oblong, obtuse divisions, 2 mm. 
long, plicate below: stamens with glabrous filaments and 2-celled 
anthers, the cells unequal: style exserted ; stigma capitate ; ovary 
acute, minutely papillose : seeds 1 mm. long, the outer coat mem- 
branous, deeply pitted. 
This is probably one of the forms included under Orthocarpus 
pilosus Watson. The leaves are not divaricately lobed as in that
