PARSLEY FAMILY 625 



with a short stiff spreading pubescence, the plant otherwise glabrous; peduncles 

 equaling or little exceeding the leaves; umbel globose-capitate; involucels 5-lobed, 

 the lobes ovate-acuminate; rays membranously winged and web-footed at base, 

 very short (1 to 2 lines long) ; fruit densely white-pubescent when young, grayish 

 in age, sessile, globose, the calyx-teeth evident; pedicels of sterile flowers equaling 

 or only slightly exceeding the fruit; oil-tubes 3 to 5 in the intervals, 4 (or 3) on 

 the commissure; calyx-teeth of sterile flowers very conspicuous, star-like. 



Sandy granite mountain slopes or plateau flats, 6000 to 12,000 feet : southern 

 Sierra Nevada from Kearsarge Pass to the upper Kern River basin. July, f r. Sept. 



Tax. note. — The species in this work called Oreonana dementis Jepson (1925) was first 

 proposed as new by M. E. Jones in 1912 (Contrib. W. Bot. 14:33). In that year Jones definitely 

 named this species as a Drudeophytum and published it (I.e.) as such, "Drudeophytum Clementis 

 n. sp." There can, therefore, be no question as to his intent, though he adds the following sentence : 

 "I have named it Pycnothryx Clementis provisionally but put it here [that is in Drudeophytum] 

 for the present until the status of Deweya Hartwegi is fixed, which is the type of the genus." 

 Pycnothryx (1912) is, however, not acceptable as a genus name under the International Eules of 

 Nomenclature, because names published without definite intent are invalid. Moreover, in this 

 case there is also conflict of intention. The author cannot, obviously, refer the species definitely 

 to the genus Drudeophytum and at the same moment in the same paragraph refer it to a proposed 

 new genus Pycnothryx. Since both proposals cannot be right, the first plainly has the greater 

 weight.

2. 0. vestita Jepson. Woolly Parsnip. Plants 2 to 4 inches high; herbage 

 and inflorescence densely woolly, the wool obscuring the leaf -segments and par- 

 tially the rays; umbels dense, equaling or mostly raised above the leaves; involucels 

 of lanceolate 3 to 5-lobed bractlets; rays 6 to 10 lines long, not winged; sterile 

 pedicels 4 to 6 lines long, greatly exceeding the fruit; fruit sessile or nearly so, 

 ovate-oblong, soft-pubescent, 2 lines long; oil-tubes 3 or 4 in the intervals, 3 on the 

 commissure ; calyx-teeth of sterile flowers evident but not conspicuous.

14. VELAEA DC. 



Subglabrous perennials with thick yellow elongated odorous taproots. Leaves 

 mostly basal, pinnately or temately compound. Ours usually without involucre, 

 the involucels in our species of few small lanceolate bracts. Flowers yellow, in com- 

 pound umbels. Fruit oblong or orbicular, somewhat laterally compressed, with 

 acute or filiform equal ribs. Oil-tubes conspicuous, 3 to 6 in the intervals, 4 to 10 

 on the commissure. Seed-face strongly involute, inclosing a central cavity. — Spe- 

 cies 7, Pacific North America. (Sebastian Eugenio Vela, student of the Umbel- 

 liferae.) 



Leaves simply pinnate ; ribs of carpel prominent. — Subgenus Deweya 1. V. arguta. 



Leaves temate ; ribs of carpel filiform, slender or inconspicuous. — Subgenus Drudeophytum. 



Ultimate leaf -segments 1 to 2 inches long; bractlets conspicuous, often exceeding the um- 

 bellet; fruit 3 to 4 lines long 2. V.hartwegii. 



Ultimate leaf -segments usually less than 1 inch long; bractlets inconspicuous, shorter than 

 the umbellets.
