Mr. Schivcinitz on the Genus Viola. 61 



harha brevissima, globoso-clavata. Infimo iiudo, limbo 

 acuto nee rotundato, postice naviformi, carinato. Calycis 

 laciniis glabris, submarginatis, oblongis acutis. 



Scapis quadratis, canaliculatis, longioribus foliis. Stipu"- 

 lis binis brevissimis versus apicem scapi sitis. 



Capsulis glabris. Radice saepe obliqua parum radicu- 

 losa. 



The general habit of this species, is much taller and 

 stricter than the former species. The flowers have a re- 

 markably deep blue or indigo color with scarcely a tint of 

 red in them. It is almost exclusively found in swampy 

 meadows, or on the grassy margin of small branches. Not 

 rarely it flowers there indiscriminately with the former, al- 

 though it begins to appear rather later. The following con- 

 trast of the characteristics will serve to distinguish the two 

 species. 



V. cucuUata V. obliqua 



Stipulis radical: minoribus, linearibus. = majoribus, uncialibiis, lauceolatis. 

 Scapis : teretibus, brevioribus. = quadratis, long^iodbus. 



Pelalo infimo : rotundato, barbato. = limbo acuto, carinato, imberbi. 

 Barha laleralium; magna, cylindrica. = brevissima, globoso-clavata.

Elliott, p. 297. n. 3. Walter, p. 219. 



Nuttall, p. 148. n. 6. exclusive ofvar/3 cordifolict. 



Muhl. Cat n. 2. harhata, by specimens, confounded how- 

 ever with cordifolia. 



The Sororia of Pursch and Willdenow belongs decidedly 

 to the next, which I think specifically different. 



V. Acaulis. Foliis rotundato-cordatis ac reniformibus, 

 obtusis, crenatis, terrae adpressis planissimis tenuioribus ; 

 sinu parvo sed aperto, rectilineo, integro; pagina superiori 

 pilis longis pubescentibus, immo pube canescentibus ; va- 

 riegatis venis purpurascentibus, demum et in siccis evan- 

 idis; pagina inferiori, glabris, purpureo tinctis. Petiolis 

 brevioribus, glabris, marginatis, difFusis. Stipulis radical- 

 ibus minutis, purpurascentibus. 



Florihus minoribus, horizontalibus, rosaceo-purpureis. 

 Fetalis limbo rotundatis, postice attenuatis ; laieralibus, 

 barba longa alba; infimo nudo, fundo albescenti, purpureo- 

 striato. Calycis laciniis glabris, punctatis, non ciliatis sed 

 margine albescenti undulato, postice auriculatis. Stigmate 

 deflexo, marginato, cupulaeformi. 



Scapis longioribus foliis, subangulatis, glabris, rubro 

 punctatis. Stipulis minutis, oppositis, versus basin sitis.
