^/Valeriana furfures cens 



l 



Root fleshy, smooth, vertical, cylindro-conical, 1-2 dm. long, 

 usually only 6-12 mm. in diameter, but slightly enlarged at the 

 crown : stems singly (rarely more) from the crown, strict, slender, 

 striate, glabrous, 5-10 dm. high including the long inflorescence : 

 leaves largely basal, all narrow, glabrous except for a minute puber- 

 ulence on the margins and sometimes on the veins : root-leaves 

 linear-oblanceolate, entire (seemingly always so), acute at apex, 

 tapering gradually into a slender, scarcely margined petiole, 10—20 

 cm. long including the variable petiole (petiole usually much 

 shorter than the blade) ; stem-leaves few, entire or with a few ap- 

 proximate lobes, with broader, shorter, often connate petioles : 

 bracts linear : bractlets minute, ovate, acuminate, scarious margined: 

 inflorescence a greatly elongated open-paniculate cyme, often 

 more than half of the height of the plant : flowers exceedingly 

 minute, light yellowish-green, very numerous; corolla 1 — 1.5 mm. 

 long, the ovate-orbicular lobes about equalling the campanulate 

 tube: stamens 3, included, nearly sessile : fruit about 3 mm. long, 

 ovate, compressed, glabrous but minutely scurfy-rugulose, or in 

 age merely splotched with brown. 



This excellent species finds its nearest ally in V. edulis Nutt. 

 but the specific distinctions are so evident that it is almost unnec- 

 essary to direct attention to them. The enormous root, the pu- 

 bescent, semi-fleshy, pinnate leaves, the less open inflorescence, 

 the relatively large white flowers and pubescent fruits of V. edulis 

 will at once separate them. 



V. furfur esc ens was secured in a small grassy mountain valley 

 where it occurred in the greatest abundance and seemed to be un- 

 usually uniform in aspect and size of all the organs characterized. 

 Chug Creek, near Iron Mountain Station, July 2, 1900, no. 7381. 



'Chrysopsis resinolens 



Perennial, green and resin scented : root woody, conical, the 

 expanded crown bearing few to many ascending or suberect 

 stems : stems 2-4 dm. high, very leafy especially upward, 

 sparsely hispid-ciliate and minutely glandular or resinous : leaves 



numerous, erect or but slightly spreading, with minute, gland- 



tipped hairs or dotted with resinous particles, hispid-piliate es- 

 pecially on the margins ; the lower dead and falling away at an- 

 thesis ; narrowly oblanceolate, on short, hispid-ciliate petioles ; 

 the upper sessile, narrowly oblong or subspatulate, 3-5 cm. long, 

 obtuse or subacute, apiculate : inflorescence terminal, crowded,
