NOTES ON SOUTHERN VIOLETS — I 



By Homer Doliver House 



The fact that a mere superficial resemblance between two 

 species in the field can be accentuated in dried specimens to an 

 extent which has prevented their separation cannot be better 

 illustrated than in the case of the following new species remark- 

 ably distinct from Viola pcdata in the field, but losing its charac- 

 teristics to a large extent when pressed and dried. 



Viola redunca sp. nov. 



Related to V. pcdata and V. avipliata. Plants solitary, rarely 

 clustered: rootstock short, 6-1 5 mm. thick : earliest leaves short- 

 petioled, reniform-ovate in outline, lobed or divided into 3-5 blunt, 

 wedge-shaped segments, later leaves with petioles 6—15 cm. long, 

 blades dark-green above, paler beneath, divided into 5-9 linear- 

 lanceolate, acute segments, these usually with one or two teeth 

 near the ends, the outermost segments of the mature blades 

 spreading nearly at right angles to the petiole, margins minutely 

 ciliate : sepals linear-lanceolate, acute or acuminate, strongly 

 truncate at the base, 13-15 mm. long, the lateral ones 3 mm. 

 broad or more: corolla 3-4.5 cm. broad, lavender-blue, the 

 lateral pair of petals slightly smaller than the others, the upper 

 pair turned back to back ; spur of the lower petal 5 mm. long 

 or more, curved strongly upward and projecting between the two 

 upper petals, tinged with purple, flattened laterally but rounded 

 in outline at the end : capsules 8—9 mm. long ; seeds pale-brown
