Type in the U. S. National Herbarium, No. 2(H),214, collected at 

 Tryon, North Carolina, May 5, 1897, and communicated by Mr. V. 1). 

 Beadle, Curator of the Biltmore Herbarium. A violet with very pecu- 

 liar and anomalous foliage, showing athnities lo the Sagittatae, but dis- 

 tinguished from all the species of Ihal group by its odtlly shaped leaves,, 

 large flowers and broad sepals. 



Viola pruinosa. n. sp. 



Plant low (aboul 1 dm. higii), sending up numerous branching stems 

 from a very short and thick rootstock; leaves slender-petioled, pinnately 

 decompound, the ultimate divisions oblong-linear, ^^-" mm. long; under 

 surface of the dull green foliage densely clothed with short and stiff, 

 white, pruinose pubesceni-e, so thai Ihe plant appears glaucous; petioles, 

 especially those of the basal leaves, with broadly sheathing scarious. 

 margins; flowers solitary in the axils, borne on slender peduncles, rather 

 small (1-li cm. broad); sepals linear, very short; petals narrowly oblong, 

 beardless, bright yellow with purple veinings, the two uppermost i)elals 

 often entirely overcast with purple; spur wanting; capsule not observed. 



Type in the U. S. National Herbarium, No. 842, IOC), collected by John 

 B. Leiberg in Bear Valley, California, at an altitude of 2200 meters, 

 April 17, lSi)8 (No. ?>'M)1]. Related to V. I)<iu,,Ii(xii, but at once dis- 

 tinguishable on account of the small flowers and the peculiar frosled 

 appearance of the foliage. 



Gentiana citrina n. sp. 



Annual; stem simple, strict. 2-4 dm. high; leaves about six pairs, ob- 

 long or ovate-oblong, sessile or slightly clasping; inflorescence narrowly 

 paniculate, the branches 1-o-flowered, each cluster svd)t ended by a pair 

 of foliaceous bracts; flower li-2 cm. long, yellow: calyx campanulale, 

 the ovate-lanceolate, somewhat une(jual lobes longer than its lube; 

 corolla lubular-campanulate, with 4 or rarely 5 erect o\ate lobes, one- 

 fourth Ihe length of the tube, ([uite destitute of siuus-appendages; 

 throat crowned with a copious fringe of setae; capsule sessile. 



Type in U. S. National Herbarium, No. 22,087, collected by C. G. 

 Pringle in the valley of Toluca, Stale of ^lexico, August IS, 1892 (No. 

 4190) and disi rihuled as (r. Wii(j]itii A. (iray, fi'om which it differs in 

 certain important particulars. In his descripl ion of \Vrl(/htii \)y. VtVA\ 

 emphasizes the fact that the leaves nearly ecjual the internodes; the 

 calyx lobes are said to have scabrous margins and the corolla is campan- 

 ulale-runncl-rorm with lobes fully one-lliird the length of the lube. I 

 have also examiiie<l the type <)f (1. Wrujiitii. which was collected in 

 southern Arizona, and tind lillle in common between the two species ex- 

 cept the characters of the subgenus to which both belong. Mr. Prin- 

 gle's No. 42;!7, also fiom Toluca, collected at an altitude of ll.dOO leel, 

 is e\idently a depauyxM-ate al])iiie form of (!. cUriiin.
