and somewhat villous upon the midrib beneath, 3 or 4 inches long, 
half as broad; segments about 7 pairs, irregularly toothed or 
again somewhat pinnatifid; petioles slender, about an inch long: 
peduncle solitary, slender, 14 inches or more in length: head half 
inch or more broad; involucre campanulate : scales ovate, acutish, 
strongly pubescent on both surfaces: true ligulate flowers none, 
the marginal disk-flowers bilabiate and ray-like, bisexual; the 
others regular, 5-parted, pubescent on the outer surface of the tube: 
scales of the disk unequally 3-parted and strongly striate.—Col- 
lected on Duncan Island, August, 1891. Apparently near S. incisa 
Hook. fil., but differing from the description of that species in its 
slender peduncle and ovate acutish involucral scales. 
Acnistus sp. Arborescent shrub: branchlets glabrous, cov- 
ered with grayish bark, leaf-bearing at their ends: leaves obovate- 
elliptic, entire, rounded at the apex, 2 to 4 inches long, 1 to 14 
inches broad, attenuate at the base to slender petioles (half inch 
long), thin, bright green, puberulent and finely punctate above, 
paler and soft pubescent beneath: pedicels axillary, rather few in 
a fascicle, filiform,somewhat thickened toward their ends, spread- 
ing or pendulous, nearly an inch in length: calyx broadly cup- 
shaped, about 2 lines long and broad; the limb subentire: corolla 
funnel-shaped, about an inch long, externally pubescent; throat 
gradually ampliate; limb 5-lobed; lobes ovate, obtusish, ciliated : 
stamens inserted a little below the middle of the tube, included : 
stigma obscurely 2-lobed.—Collected on Chatham Island, June, 
1891. Apparently near A. ellipticus Hook. fil., but differing in 
its pubescent leaves and in having a corolla about twice as long 
as described for that species. , 
SoLtaNacEA sp. Densely pubescent herb with habit, inflores- 
cence, and foliage of Datura: leaves broadly ovate (in some 
cases broader than long), open cordate, shallowly sinuate-toothed, 
2 to 3 inches in diameter, above green, glabrous or nearly so, 
under lens finely papillose-punctate, below pubescent upon veins, 
not paler; petioles pubescent, as long as the leaves: peduncles an 
inch or so long, axillary, solitary, 1-flowered, deflexed in fruit: 
‘calyx short-cylindric from an ovate base, densely pubescent, very 
obscurely angled, 4 to 5 lines long, persistent in young fruit; the 
limb of 5 erect unequal linear teeth: corolla funnel-formed ; tube 
rather slender, 14 inches long including the but sligbtly ampliate 
throat ; limb spreading, very shallowly 5-lobed, inch in diameter: 
anthers longitudinally dehiscent: young fruit ovoid, smooth, 3 or 4 
lines in length, loosely surrounded by the calyx.—Collected on 
Hood Island, July, 1891. A plant certainly new to the flora of 
the islands and of interesting, apparently somewhat anomalous 
generic affinities, possessing on the one hand the corolla, smooth- 
ish fruit, and more. or less persistent calyx of Nicotiana, but the 
leaves, axillary inflorescence, and general habit of a Datura. 
Insufficient material prevents a more accurate disposition.
