BICKNELL: FERNS AND FLOWERING PLANTS OF NANTUCKET 121 
rounded or subcordate at base, 4.5-7 cm. long, 2.5—5 cm. wide, the 
stalk about 2 cm. long; middle leaflets obovate-elliptic or oblong, 
rounded or somewhat cuneate at base, subsessile or on petiolules 
sometimes I cm. long; flowering branchlets 8-15 cm. long, bearing 
below about two frequently reduced trifoliolate leaves and above 
a single, oval or orbicular, often cordate, unifoliate leaf; inflores- 
cence a slender pubescent raceme, its axis sparsely setulose and 
bearing some slender gland-tipped hairs; pedicels slender, ascend- 
ing, or spreading, I-3 cm. long, subtended by greenish bracts 
. . or the lower axillary from the leaves, unarmed or nearly so, 
pubescent and bearing few or numerous gland-tipped hairs; 
calyx lobes softly pubescent, attenuate; flowers rather small, 1.5- 
2.5 cm. wide; petals oblong to obovate-oblong. 
Bank of Reed Pond, June 18, 1910, in full flower, erect-ascend- 
ing and partly trailing forms; Tom Never’s Pond in low thicket, 
erect form; not yet in flower June 13, 1908, in full flower June 24, 
1910. On Long Island I have collected a similar erect form from a 
single colony near Jamaica. 
Widely different aspects are presented by the erect and the 
partly trailing states of this plant, and but for their obvious 
intergradation two different crosses might be supposed. In the 
erect forms the racemes are sometimes almost without glandular 
hairs and are small and somewhat appressed along the upper part 
of the stem. On the spreading forms the larger racemes terminate 
conspicuously leafy branchlets, and the pedicels are often clothed 
with gland-tipped hairs, sometimes twice the length of the pubes- 
cence. 
* RUBUS FRONDOSUS X PROCUMBENS. 
R. multispinus Bld. 
At several stations. In full flower June 18, 1908; ripe fruit 
August 4, 1906, September 20, 1899. d 
Stems commonly more slender and trailing than in Rubus 
argutus X procumbens, armed with fewer, shorter and_broader- 
based, more hooked prickles; leaves more pubescent, more ovate 
and long-acuminate, the marginal pattern more coarsely serrate; 
inflorescence more leafy-bracted and corymbose, with longer, more 
erect pedicels.
