adopt, for the present at least, Chapman’s name, about which 
there can be no doubt, as above stated. The P. caespitosum longi 
Solum of Dr. Vasey would seem to me hardly worthy of the rank 
of a variety, as both long and short leaves occur on the same 
plant. 
PaspaLum SIMPSONI n. sp. 
Culms, upper sheaths, and surfaces of the leaves smooth and 
glabrous. Culms erect, slender, 2-8 dm. tali; sheaths loosely em- 
bracing the culm, the basal ones short and appressed-villuos, - 
the remainder longer and usually much exceeded by the inter- 
nodes of the mature culms, the uppermost one elongated; ligule 
very short and truncate; leaves erect or ascending, lanceolate, or 
linear-lanceolate, 2.5-14 cm. long, 2-10 mm. wide, rounded or 
slightly cordate at the base, acuminate at the apex, ciliate, glau- 
cescent above ; inflorescence 8-16 cm. long, the first internode of 
the main axis 3.5-5 cm. in length, the remainder gradually be- 
coming shorter; spikes usually strict, 3-5, spreading or ascending, 
2.5-7.5 cm. long, pubescent and pilose at the base, the rachis flat, 
winged, one-half to two-thirds as broad as the spikelets, narrower 
and more or less flexuous:toward the apex, minutely scabrous on 
the margins; spikelets in 4 rows, in pairs on flattened minutely 
scabrous shorter pedicels, obicular-obovate, 1.5 mm. long, the two 
outer scales membranous, 3-nerved, the first one concave, pubes- 
cent with short spreading glandular-tipped hairs, the second flat, 
glabrous, or sparingly pubescent at the very base, the third scale 
chartaceous, concave, smooth and shining, yellowish, enclosing a 
palet of equal length and similar texture. 
Collected by J. H. Simpson on No Name Key, Florida, in May, 
1891, no. 184. I take pleasure in naming this grass in honor of 
Mr. Simpson, whose extensive collections in southern peninsular 
Florida, have added much to the knowledge of the flora of that — 
Most interesting region. The Paspalum in question has been cun- 
founded with P. caespitosum Fluegge, a discussion of which species 
Occurs above under P. Blodgettii, and Mr. Simpson’s plant, referred 
to Previously, was distributed under the former name. Curtiss 
No. 5440, collected at the same locality on June 26, 1895, is this _ 
Same plant and was also distributed as P. caespilosum, — : 
This grass is readily distinguished from P. Blodgetti, to which 
it is related, by its smaller and differently shaped spikelets, the * 
Pubescence of which is short, spreading and glandular-tipped, and a 
by the broader and manifestly ciliate leaves. — The spikelets a
