diametro.) (Vide figuram.) PeUilum inferius aspectu reliquis 

 subaequilongum, concaviini, obtusissimum vel minute retusum, 

 nudum, lineis violaceis supra medium vel apicem versus ramosis 

 eleganter notulatis. (Lineae in petalis lateralibus paucae minus 

 ramosae et in superioribus tantum binae vel ternae simplices.) 

 Bracteolae at medium pedunculi breves lineares subulatae appositae. 

 Calcar breve rotundatum purpureis vel violaceis puncticulis ex- 

 terius coloratum. 



Flores apetali aestivi, subterranei sed se ad superficiem fructu 

 facto erigentes, sepalis 5 verisimiliter subaequalibus acutis, ad 

 apicem involutis, et pistillum cum duobus staminibus appresse 

 includentibus, stylo longo brevi hamato vel incurvato staminibus 

 binis appendiculatis alatis compresso: stigmate binis vel quaternis 

 staminum antheris appresso. Aliquando tertium adest parvum et 

 omnino sterile stamen inter altera insitum, vel cum duobus vel 

 tribus minutis tuberculis ad pistilli basim. Folia prima reni- 

 formia, viridescentia, crassula, rotunda, cordata, apice obtuso 

 vel rotundato, margine crenato vel obtuse serrato. Folia aestiva 

 majora ad apicem plus elongata circa 6.8 cm. lata et usque 7.5 

 cm. longa, perglabra, vel cum perpaucis minutis pilis in venis ad 

 apicem superficiei. 



In locis humidis sed arenosis inter gramina et carices ad 

 stagnorum ripas crescere invenitur. 



Spring plant about 13 cm. high perfectly glabrous growing 

 in clumps: leaves never becoming as long as the flowering ped- 

 uncles until the summer phase, usually about one half as long. 

 Lower sepals about 7 mm. long obtuse or rounded, glabrous, 

 obscurely 3-nerved, the margins narrowly scarious or membranous. 

 Corolla pure white (!) broader than long: the upper petals broadly 

 obtuse or rounded, suborbicular, 12 mm. long, 10 mm. wide or 

 wider, the lateral ovate or obovate, obscurely retuse, bearded 

 with short and long clavate hairs: (the larger hairs 1.7 mm. long 

 about 24 fi wide below, and 57-99 ^i near their apex; the shorter 

 ones more obtuse or rounded) (Fig. 4.) Lower petal apparently 

 in flower equal in length to the others, concave or somewhat cari- 

 nate obtuse or slightly retuse, naked, elegantly striped with cross- 

 branched violet lines to above the middle, the striations on the 

 lateral and upper petals are much fewer, only about 3 in the 

 latter. Bracts short subulate linear on the middle of the peduncle,
