the branches, stout or occasionally acicular. Petiole 3/’-6” long, 
often spiny; stipular sheath % to % its length and frequently 
denticulate on the margins. Blade mostly coriaceous, sometimes 
rather thin, varying from broad-ovate to (more commonly) deltoid- 
hastate, hastate or panduriform (S. pandurata Pursh), green or 
shining on both sides, smooth or often denticulate or spiny on 
the margins and nerves beneath, especially in the southern hastate 
forms (S. hastata Willd., S. bona-nox B L.), acute or abruptly cusp- 
idate at the apex, obtuse truncate cordate or semicordate at the 
base, pellucidly punctate and lineolate, 5—9-nerved, 114’-414’ long, 
8”_214’ wide. Peduncles slender, compressed, 7-14” long, 15-45- 
flowered. Pedicels 2”_4” long. Segments of male perianth lan- 
ceolate, 2”_214” long; anthers as long as the filaments. Segments 
of female perianth 1’ long; ovary 3-celled, often only 1-ovuled; 
stigmas 1-3. Berries black, globular, 8-20 in number, 2’’—3” in 
diameter, mostly 1-seeded. 
The leaves of this species are very variable in shape. They 
are sometimes merely ovate with an obtuse, abruptly cuspidate 
tip, more commonly deltoid-hastate with broad, rounded lobes at 
the base, sometimes constricted above the lobes, acute and cus- 
Pidate at the apex, running from this into narrow, hastate forms, 
with Projecting, rounded lobes at the base, and an oblong, narrow, 
terminal lobe, the apex obtuse or acute and cuspidate. These 
natrow forms, are sometimes only 6” broad across the basal 
lobes, and 3” in width on the terminal lobe, and are often quite 
Spiny-bristly on the margins. Others again are fiddle-shaped, 
with 2 broad, rounded lobes at: the base, expanding above the 
“ontracted middle into a broad obtuse and cuspidate or acute 
"pper lobe. The venation is often somewhat peculiar, the main 
reticulations being oblong, beginning low down on the blade, giv- 
ing the appearance of a multitude of basal nerves, with secondary 
nerves as prominent as the primary. The nerves are 5-7 on the 
terminal lobe, and often from 2 to 4 additional ones on the basal 
lobes, The margins have a raised callous edge. 
In specimens collected by Dr. Gattinger in Tennessee (Herb. 
University of Tenn.), the stem exhibits in places little cushions or 
: Pads of stellate hairs, and large flat spines having the same kind 
: mt hairs upon them. In these instances the branches are flexuous, 
_ With short nodes, as in S. rotundifolia. In other cases I have seen 
forms with these stellate hairs on the nerves of the leaf, and at 
“le extremities of the spines, swamps and thickets. ;
