PARSLEY FAMILY 645 



Field note. — The petioles are mainly subterranean, straw-white, very wide, and serve, as is 

 often the case, to protect the embryonic shoots. The relationships of this species are mainly with 

 L. caruif olium C. & R. Typically the herbage of L. caruifolium is minutely pubescent, while that 

 of L. marginatum is glabrous (except sometimes the rays). There are, however, specimens of L. 

 caruifolium with glabrous or glabrate herbage: San Luis Obispo Co., Unangst ; Crystal Lake, San 

 Mateo Co., C. F. Baker 426.

20. L. triternatum C. & R. Buck Parsnip. Plants IV2 to 2% feet high; herb- 

 age minutely puberulent ; peduncles arising from the root-crown or borne on stems 

 3 or 4 inches long, the parts at base sheathed by scale-like petioles; leaves twice or 

 thrice ternate, then pinnate, the leaflets distant, narrowly linear, acute or long- 

 acuminate, 1 to 5 inches long, ^2 to 11/4 (or 3) lines wide; flowers bright yellow; 

 fruiting rays very unequal, 1 to ZY2 inches long; bractlets setaceous; fruiting pedi- 

 cels 1/^ to 2^/^ lines long; fruit oblong to linear, glabrous, 5 to S^/^ lines long; dorsal 

 and intermediate ribs prominent, the wings lialf the breadth of the body; oil-tubes 

 large, broad, 1 in each interval, 2 on the commissure.

Field note. — The roots are gathered and dried for food by the Indians ; they contain much 

 starch and have a mild sweet taste (Pac. R. Rep. 2 :121).

LoMATiUM GIGANTEUM C. & R. Contrib. U. S. Nat. Herb. 7:240 (1900), type collected by 

 Vasey in Cal., "probably" Mendocino Co. ace. to Coulter and Rose, who also cite Bolander 6521 

 (by error "5521", which number does not exist in the Bolander Field Book), Elk Ridge, nw. 

 Mendocino Co.; Jepson, Man. 725 (1925). Cogswellia gigantea Jones, Contrib. W. Bot. 12:32

 Ridge, nw. Mendocino Co., Bolander 6521. Peucedanum nudicaule var. puherulum Gray in 

 herb. Apparently Lomatium giganteum has not been re-collected since early days. Possibly 

 it is an outlying representative of some northern species (Oregon or Washington), such as 

 Lomatium triternatum C. & R., Trinity County material of which, such as Hayfork Mt., Tracy 

 6439, resembles Bolander 6521 rather closely. We have not seen the Vasey type, but the type of 

 Peucedanum nudicaule var. puherulum Gray, that is Bolander 6521, is the collection cited by 

 Coulter & Rose under Lomatium giganteum. The following notes are based on Bolander 6521 

 with quoted additions from the original character: Stems 14 to 17 inches high; herbage minutely 

 puberulent ; leaves in a basal tuft, 5 to 7 inches long, ternate, the divisions of the petiole elongated, 

 pinnately 3 to 5-foliolate at the middle or above; leaflets linear to oblanceolate, 1 to 1% (or 

 "3%") inches long; peduncles scapose, naked save one reduced leaf above the middle, not en- 

 larged at summit; rays 5 or 6, very unequal, i/^ to IY2 (or "4%") inches long; bracts none; 

 bractlets subulate; ovary glabrous or "pubescent"; "fruit linear-oblong, glabrous or nearly so, 

 9 lines long, the wings much narrower than the body."
