CATALOGUE. 131 



It is apparently not the Var. ellipticum of Beckwith's collection in the Sierras 

 of Northern California. As observed by Dr. Gray, the plant does not accord 

 with Nuttall's description, nor in all respects with the characters of the 

 genus ; the lateral wings, however, are contiguous until the full maturity of 

 the seed. Very frequent in Western Nevada from the Washoe to the West 

 Humboldt Mountains, and the eariiest flowering plant of spring; 4,500-6,000 

 feet altitude ; March-June. (469.) 



Peucedanum (!) VILLOSUM, Nutt.-MSS., (in Herb. Gray.) Caulescent 

 or often nearly acaulescent, from a deep often branching rootstock, pruinose- 

 pubescent ; leaves with broadly dilated scarious petioles, 2-3-pinnate and 

 sometimes ternate, the segments laciniately lobed, often minute and 

 crowded ; stems 3-10' high, with one or more subcapitate umbels ; the 

 rays elongating in fruit; involucre none; involucels unilateral, of several 

 distinct linear-subulate membranous-margined leaflets ; calyx-teeth small ; 

 petals yellow, narrower than in the last ; fruit similar. — Collected by 

 Nuttall on the plains of the Platte ; Nebraska, (Hayden ;) New Mexico, 

 (Newberry ;) and near Virginia City, (Bloomer.) Resembling P. dasy- 

 carpum (which includes P. tomentosum) in habit, but difiering in the 

 involucels, more capitate umbels, less tomentose fruit and especially in its 

 more numerous vittae. It is P . fceniculaceum, r-, T. & G. Western Nevada, 

 from. the Washoe to the Battle Mountains; 5-8,000 feet altitude; April- 

 June. (470.) 



Heeacleum lanatum, Mx. From North Carohna to Kentucky and 

 northward to latitude 58° ; Missouri, New Mexico, and on the western coast 

 from Sitka to Monterey. Found in the Goose Creek Mountains, Utah, and 

 frequent in the Wahsatch ; 6,000 feet altitude; July-October. (471.) 



CoRiANDEUM SATIVUM, L. Ditchbank, Unionville Valley, Nevada; 

 introduced. (472.) 



CORNACEiE. 



CoENUS PUBESCENS, Nutt. MSS. (C sericea, ^. ? occidentalism T. & G.) 

 Branches suberect, branchlets spreading, more or less reddish, puberulent 

 when young ; leaves ovate or elhptical, acute or acuminate, slightly pubescent, 

 as well as the somewhat crowded cymes, obtuse or acute at the base ; calyx- 

 teeth minute ; petals oblong-lanceolate, rather obtuse ; drupes subglobose, 

 white, becoming lead-color. — On stream-banks in mountain canons; 6-8°
