130 Poltdi'd Xetr Specie.* of Xorth Aincricn 



ovate-lanceolate, acute, auriculate at base; petals oblong, bearded, the 

 spur short and blunt: capsule prismatic, one-third longer than tin 1 calyx; 

 apetalous flowers borne on evidently erect scapes. 



Type in the U. S. National Herbarium, No. 200,214, collected at 

 Tryon, North Carolina, May f>, 1897, and communicated In Mr. ( '. 1). 

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

 liar and anomalous foliage, showing Affinities to the Sagittalae, but dis 

 tinguished from all the species of that group by its oddly shaped leaves, 

 large flowers and broad sepals. 



Viola pruinosa. n. sp. 



Plant low (about 1 dm. high), sending up numerous branching stems 

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

 decompound, the ultimate divisions oblong-linear, 5-7 mm. long* under 

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

 white, pruinose pubescence, so that the 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 petals 

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



Type in the U. S. National Herbarium, No. 342,190, collected by John 

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

 April 17, 1898 (No. 3307). Related to V. Douijlaxii, but at once dis 

 tinguishable on account of the small flowers and the peculiar frosted 

 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 1-5-flowered, each cluster subtended by a pair 

 of foliaceous bracts; flower 1^-2 cm. long, yellow: calyx campanulate; 

 the ovate-lanceolate, somewhat unequal lobes longer than its tube: 

 corolla tubular-campanulate, with 4 or rarely 5 erect ovate lobes, one- 

 fourth the length of the tube, quite destitute of sinus-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, State of Mexico, August 18, 1892 (No. 

 419(5) and distributed as (i. \YritjJttii A. Gray, from which it differs in 

 certain important particulars. In his description of Wri(jJitii Dr. Gray 

 emphasizes the fact that the leaves nearly equal the internodes: the 

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

 ulate-funnel-form with lobes fully one-third 1 the length of the tube. I 

 have also examined the type of G. \Vri<//itii. which was collected in 

 southern Arixona, and find little in common between the two species ex 

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

 gle's No. 4237, also from Toluca, collected at an altitude of 11,000 feet, 

 is evidently a depauperate alpine form of (}. ritrinn.
