58. Lomatium giganteum C. & R., sp. nov. 
Caulescent or sometimes acaulescent, 4 to 7 dm. high, finely pubes- 
cent throughout; leaves very large, ternately compound; leaflets 
elongated, sometimes reaching 8 cm. in length, usually entire, very 
pale; rays very unequal, the longer ones 10 cm. long; pedicels 2 to 4 
mm. long; involucel of linear bractlets; ovary pubescent; fruit linear 
oblong, f8 mm. long, with wings much narrower than body, glabrous 
or nearly so. 
Resembling ZL. suAsdorf? in its stout habit, but with more elongated 
leaflets, pubescent ovaries, smaller fruit, ete. 
Type locality, California; collected by G. 2. Vasey in 1875; type in 
U.S. Nat. Herb. 
Western California. 
Spectinens examined: 
CairorntaA: Mendocino County, Bolander 5521. in L867; probably same station, 
Vasey, in 1875. 
“Peucedanum (Ferula, Gey.) tenuissimun Gey, MS.’ (in Hook. Lond. Journ. 
Bot. 6: 285. 1847) is still doubtful. [Tt is probably a good species, but more 
than likely has been described under some other name. 
Peucedanum triternatum leptophylliin Wooker |. ¢. is also uncertain. 
Both of these types are probably in the British Museum. Material which seems 
to represent these two forms was sent to Mr, E.G. Baker for comparison, and it is 
to be regretted that his report, now in transit, can not be incorporated in this work. 
Peucedanum jaredi Eastwood (Zoe 5: 88. 1900) isa new name which has come to 
us during the final proof revisian. 
59. EURYPTERA Nutt. in Torrey & Gray, Fl. 1: 629. 1840. 
Calyx teeth minute or obsolete. Fruit strongly flattened dorsally, 
orbicular to shortly oblong. Carpel with filiform and approximate 
dorsal and intermediate ribs, and with broadly winged laterals (often 
much broader than the seed body and more or less distinet at base, 
making it cordate or emarginate) cohering until maturity with those 
of the other carpel; pericarp thin, Stylopodium wanting: disk 
impressed, Oil tubes one to several in the intervals. Seed strongly 
dorsally flattened, with plane face. 
Acaulescent or caulescent glabrous perennials, with elongated roots, 
branching only at base, leaves once or twice compound, leaflets 
either broad or broad in outline and always sharply toothed, and yel- 
low flowers. 
Type species, Auryptera lucida Nutt. 
A genus of 6 species belonging to the Pacific coast and islands. 
The genus differs from typical Lomatinn especially in its foliage, which is much 
more simple, with broad often orbicular leaflets, and sharp mucronate teeth. The 
wings of the fruit are inclined to be distinct, while in Lomatium the wingsare united 
and project below the seed. Nuttall’s genus Huryptera, based on a single species, 
was published by Torrey & Gray in 1840, but was reduced to a section of Peuceda- 
num by Bentham & Hooker in Genera Plavtariin in 1867, where it has since remained.
