Class V. Order I. 95 



ibund smooth and bearded. Both are somewhat fragrant, the 

 blanda most distinctly so. Meadows. May. Perennial 



These two violets, with almost every intermediate form of 

 the leaf, grow together abundantly in wet, open situations about 

 this city. I am not without suspicion, that they are all descend- 

 ants of one species. 



* VIOLA ACUTA. Jlcute Violet. 



Acaulls ; foliis ovatis, glabris, petalis acutis, 



albis ; bracteis petala longitudine subcequantibus. 



Stcmless ; leaves ovate, glabrous ; petals acute, 

 white ; bractes nearly as long as the petals. 



This is our smallest native violet, and after observing it for 

 several years I am satisfied that its characters are sufficiently 

 permanent to render it a distinct species. Among the other 

 white violets it is noticeable by its even and always acute petals, 

 and likewise well distinguished by its long linear bractes which 

 greatly exceed those of any similar violet. Root creeping. Sti- 

 pules linear subulate, sometimes a little ciliate-toothed Leaves 

 ovate, smooth, crenate, rather obtuse. Petioles mostly smooth, 

 and shorter than the leaves, hardly winged, but in dry soils ciliate 

 with reflexed hairs. Scapes four sided, supporting a pair of 

 Unear-lanceolate, foliaceous, incurved bractes, which are nearly 

 as long as the petals. Calyx smooth, acute. Petals oval, re- 

 markably even or tlat, and acute, the odd one obovate, striate 

 with purple at base, the lateral ones slightly striate, and rarely 

 bearded. Stigma capitate, rostrate. Grows in Cambridge, par- 

 ticularly about the pine trees on Craigie's road, in moderately 

 damp soil. May, June. Perennial. 



VIOLA PALMATA ? fVilld. Palmated Violet. 



Stemless ; pubescent, leaves cordate, hastatc-lo- 

 bate or palmate, the divisions toothed ; segments of 

 the calyx lanceolate, smooth. 



Hoot denticulate. Petioles hoii-y. Leaves pubescent, veiny, 

 with a long crenate, subacute middle lobe, and one or two 

 lateral lobes, the base cordate. The first leaves are simply cor- 

 date. Stipules lanceolate, ciliatc-scrrute. Bractes linear, about
