SOME NEW TEXAS PLANTS. 121 
Dry sandy soil along streams, eastern and central 
Texas. Summer. 
P. subulata is allied perhaps more nearly to P. hypogaea 
Nutt., butis abundantly distinct from that species in the 
larger differently shaped leaflets, larger and longer spikes, 
and different habitat, P. hypogaea Nutt. growing on the 
rich prairies about Dallas. It is easily distinguished from 
P. esculenta Pursh, by its nearly acaulescent habit, dif- 
ferently shaped leaflets, larger and stouter petioles, differ- 
ent habitat, and the long subulate beak of the pod. 
Specimens examined: Texas; Dallas County, Bush 697, 
May 10, 1900, type: Hempstead, Hall 1350, June 28, 
1872. 
PsoORALEA PALUSTRIS 0. sp. 
Perennial from a deep elongated tuber. Stems 6-9 dm. 
tall, slender, erect, simple, unbranched, strigose-hirsute ; 
stipules linear-subulate; leaflets 3, the blades lanceolate to 
narrowly oblong, strigose-hirsute, 4—7 cm. long, and 1-1.5 
cm. wide, rugose-veiny, acutish; peduncles 5-10 cm. long, 
as long as or longer than the subtending leaves, equalling 
or exceeding the racemes in length; racemes 4—5 cm. long, 
not elongating in fruit; pedicels of the flowers 3-6 mm. 
long; tube of the calyx campanulate, thickly glandular- 
dotted; corolla 6-9 mm. long, deep purple; bracts linear- 
aristate ; pods suborbicular, apiculate by the style, 4-5 mm. 
long, strongly transversely wrinkled, scarcely margined, 
thickly glandular-dotted. 
Sandy swamps, eastern Texas. Summer. 
This species differs from P. pedunculata (Muhl.) Vail, 
in the taller, unbranched stems, more strigose foliage, 
larger and longer leaves, longer pedicels of the flowers, 
lax racemes, shorter peduncles, and especially in the © 
marshy habitat, and in the large deep purple flowers which 
are produced much later in the season, P. pedunculata
