4. Conioselinum pacificum (Watson) C. & R. 
Selinum pacificum Watson, Proc. Am. Acad, 11: 140, 1876, 
Stout, 3 to 6 dm. high; leaflets 2.5 cm. long, laciniately toothed and 
lobed; umbel (on stout peduncle) about 15-raved, with a conspicuous 
involucre of 2 or 3-lobed and toothed leaflets 2.5 cm. long and equal- 
ing the rays, and involucels of ‘several narrowly linear or spatulate- 
linear bractlets, entire or 3 to 5-toothed or laciniately lobed above, 
equaling or exceeding the flowers; pedicels 4 to 8 mm. long; fruit 
oblong, 6 to 8 mm. long, 3mm. broad, with rather narrow thin wings; 
oil tubes solitary in the intervals or a small additional one in a lateral 
interval. 
~ Type locality, ‘ton the Saucelito hills, near San Francisco,” Cal. ; 
collected by Aellogg & Harford, no. 315, in 1868-69; type in Herb. 
Gray, duplicate in U. S. Nat. Herb. 
Only known from the type locality. 
Specimens examined: 
CALIFORNIA: Type specimens as cited under type locality. 
This is a very rare species and seems to be extinct at the tvpe locality. At least, 
Miss Alice Eastwood has examined for several years past all the hi'ls about Sausalito 
and San Francisco without finding it. A specimen of this species is in herbarium of 
the California Academy of Science and is said to have been collected at Long Val- 
ley, Mendocino County, by A. Kellogg. The label, however, is not an original one, 
and Californian collectors are urged to keep this plant in mind.

pedicels 2 to 4 mm. long; fruit oblong, about 4mm. long, with promi- 
nent wings, the lateral ones but little broader; oil tubes solitary in the 
intervals or a small one in a lateral interval.
