in P. setacea they are longer. The calyx of the new species is 
sharply diagnostic, being urn-shaped with a much enlarged base, 
the calyx of P. setacea being turbinate and narrowed at the 
base. The cusps terminating the sepals are much stouter and 
only about one-half as long as the very slender cusps of P. setacea. 
Mr. Heller’s number 1729, distributed as P. setacea, is Paronychia 
chorizanthoides, but, being quite young, it has not yet assumed the 
characteristic habit that Dr. Palmer’s specimens exhibit. 
SIPHONYCHIA CORYMBOSA. 
Perennial, stoutish, the foliage pubescent with recurved hairs. 
Stem branched at the base, the branches tufted, 1-3 dm. tall, erect 
or ascending, olive-green or brownish, forking, especially above, 
ribbed, topped by the corymbosely disposed cymes ; leaves oblan- 
ceolate to oblong-oblanceolate, .5-1.5 cm. long, acutish, ciliate, 
sessile; stipules ovate, silvery, long-acuminate; inflorescence sil- 
very; calyx 2-2.2 mm. long, pubescent at the base, the segments 
oblong or ovate-oblong, white, longer than the tube, obtuse, con- 
cave, slightly hooded at the apex; stamens included; style ex- 
serted; utricle ovoid, 1 mm. long. 
The original specimens were collected by Professor L. M. 
Underwood on Ship Island, on the coast of Mississippi, in June, 
1896. 
Siphonychia corymbosa is most closely allied to Siphonychia erecta, 
which it simulates in habit. The characteristic difference in ap- 
pearance between the two species is in the foliage, that of S. erecta 
being glaucous, while that of the new species is clothed with a 
pubescence consisting of short recurved hairs; the inflores- 
cence of Siphonychia corymbosa is more lax; the calyx furnishes 
good distinctive characters: that of the new species is shorter 
and stouter, the segments oblong, with converging tips, instead 
of lanceolate, with erect tips, as in that of S. erecta. 
Vv CLEMATIS GLAUCOPHYLLA. 
Perennial, bright green, glabrous. Stem rather slender, 2-5 
meters long, climbing over bushes or trees, nearly simple, dark 
red, furrowed, much enlarged at the nodes; leaves ovate, 3-10 cm. 
long, thickish, acute, often apiculate or acuminate, entire, 3-lobed 
or trifoliolate, with conspicuous white nerves above, prominently 
nerved and glaucous beneath, cordate or subcordate ; floral leaves 
with petioles 1 cm. long, the nerves gradually diverging from the 
midrib; flowers reddish purple, glossy, 2-2.5 cm. long; calyx
