1900] Robinson, — Variations of Ilex verticillata 105 
of the varieties (padifolia and cyclopAy//a) have been confused by re- 
cent writers, and a third (Zezuifo/ia) should have a different authority 
from the one usually cited. 
I. vERTICILLATA, Gray. Leaves oblanceolate to obovate-oblong, 
acuminate, dark green and nearly or quite glabrous above, finely pubes- 
cent, chiefly upon the midnerve and veins beneath, thickish and of 
firm texture, 3 to 7 (rarely 9) cm. long, scattered upon the branches, 
in a dried state opaque or nearly so, except along the smaller veins; 
the larger veins and midnerve usually impressed above.— Manual, ed. 
2, p. 264 (1856). Prinos verticillatus, L. Spec. i. 330.— Common 
and generally distributed in New England; by no means confined to 
“swamps,” the habitat assigned to the species by Britton and Brown. 
Var. TENUIFOLIA, Watson. Leaves of the same general although 
rather variable size and contour as in the typical form, but thinner and 
more flaccid, membranaceous, lighter green, in a dried state pellucid 
punctate, the veins not impressed above, the pubescence scanty.— 
Bibliog. Ind. 160 (1878), where the combination is erroneously as- 
cribed to Torrey, who employed ¢enujifolia, not under //ex verticillata, 
but under Prinos verticillatus, Fl. N. U. S. 338 (1824).—Less fre- 
quent than the typical form, yet not rare. From New England Ihave 
to date seen specimens from the following localities: Martner, Bangor 
(Oakes,) Stillwater, Penobscot County (Fernald), Somesville, Mt. 
Desert Island (Fernald); Massacuusetts Oak Island (Young); 
RHODE IsLAND, north of Cat Swamp, Providence (Co//ins) ; CONNEC- 
TICUT, in not very characteristic form from Southington (Andrews, 
Bissell). 
Var. cyclophylla. Leaves small, broadly obovate or suborbicular 
2 to 2.5 cm. long, 1.5 to 2 cm. broad, rugulose above, paler and puber- 
ulent upon the principal veins beneath, clustered near the ends of 
the branchlets.—//ex verticillata, var padifolia, Britton, Bull., Torr. 
Club, xviii. 314 ; Trelease, Syn. Fl. i. pt. 1, 391, in part; Britton A 
Brown, Illustr. Fl. ii. 392; not Wats., nor Prinos padifolius, Willd.— 
Collected long ago in the neighborhood of Lake Erie, without more 
exact data. Type in herb. Gray; co-type in herb. New York Bo- 
tanical Garden. Although this striking small-leaved form has been 
confidently referred to var. padifolia by Professor Britton, l. c., it is 
clear from Willdenow’s excellent description, Enum. Hort. Berol. 394, 
as well as from an authentic fragment in herb.Gray, that his Prinos padi- 
folius of Pennsylvania was a very different plant, with larger obovate- 
oblong leaves, velvety tomentose beneath. The name Pad/fo/ia, as a 
varietal designation under / verticillata, was first published by 
Watson (Bibliog. Ind. 160), its sole definition being the synonym 
Prinos padifolius, Willd. The variety thus rests exclusively upon the 
type and description of Willdenow’s species. A form bearing small, 
roundish leaves and approaching var. cyclophy//a, has been found in a 
ravine on Jordan Mountain, Mount Desert Island, Maine (Rand).
