saw a few individuals. It is possibly not rare; but I suspect that the 



material formerly referred here belongs partly or wholly to one of the 



following species. 



8i#. Lechea racemulosa Michx. 

 Hyattsville, September 7, 1896; later at Lakeland, Congress Heights, 



and in the Paint Branch region. Plants gathered at the last station 



September 3, 1900, have the fruit and leaves of racemulosa, but are most 



remarkable in habit, forming low, bushy, and extremely dense clumps, 



heavily laden with fruit. A few specimens in the National Herbarium 



somewhat approach them. They were on ground which had been 



burned over the previous year. 



Sib. Lechea tenuifolia Michx. 



Addison Heights, July 25, 1896. Probably our most common species. 



*88a. Viola Brittoniana Pollard. 



Moist ground north of Berwyn, May 6, 1900; later seen near Lakeland. 



Adding these stations to that of Mr. Pollard's at Hyattsville, it may be 



expected that this violet will be found at intervals along the low ground 



from Bladensburg to Berwyn and perhaps farther. 



S6c. Viola sororia Willd. 



Woods, Forest Glen, May 17, 1900. 



82. Viola lanceolata L. 



Bennings, both in the wet ground near the railroad and the low ground 



towards the river; low ground above Riverdale. 

 860. Viola affinis LeConte. 



Abundant in woods at foot of bluff on the Giesboro road some distance 



beyond Congress Heights, April 27, 1899. Seen also on the Potomac 

 flats east of the railroad. 

 84. Viola cucullata Ait. 



Boggy ground beyond Silver Hill, May 25, 1899, and at points in Suit- 

 land. 

 *84a. Viola laetecaerulea Greene, n. sp. 



Acaulescent, with short, stout, branching rootstock, the foliage at time 

 of petaliferous flowering upright, 4 to 7 inches high, distinctly hirsutu- 

 lous, the young and growing peduncles, petioles, and cucullate unex- 

 panded leaves often rather densely so: leaves from rounded or subreni- 

 form-cordate to cordate-ovate, and 1| to 2| inches long, evenly and very 

 distinctly crenate, obtuse, light green; peduncles stoutish, scarcely 

 equalling the petioles; sepals oblong, obtuse, very narrowly scarious- 

 margined, often more or less plainly serrulate-ciliolate; petals rather 

 broad, well rounded, indistinctly veined, the odd one very conspicuously 

 shorter and every way smaller than the others, all light-blue, the lateral 

 ones with a strong tuft of hirsute subclavate or perhaps flattened white 

 hairs; apetalous flowers and their capsules on short horizontal and more 

 or less completely subterranean peduncles; capsules oblong. 



In sandy loam, open ground, Potomac flats below Long Bridge, a few 

 clumps only, these closely associated with an abundant growth of V.
