RANUNCULACEA. 
CLEMATIS Linn. 
1. Clematis macgregorii Merrill sp. nov. § Flammula. 
Scandens, inflorescentiis exceptis glabra, dioica vel polygamo-dioica ; 
foliis trifoliolatis, foliolis ovatis, membranaceis vel chartaceis, basi 5- vel 
7-nerviis, cordatis, apice breviter obtuse acuminatis, integris vel supra 
pauce denticulatis; floribus tetrameris, paniculatis, sepalis extus ferru- 
gineo-pubescentibus, antheris apice longe aristatis. 
A scandent woody vine, glabrous except the inflorescence, dioecious or 
polygamo-dioecious. Stems at least 5 mm in diameter, terete, covered 
with very large lenticels, the branchlets slender, striate, grayish- or reddish- 
brown. Leaves 3-foliolate, or the upper ones sometimes simple, their 
petioles 2.5 to 7 cm long, the petiolules 1.5 to 3 em long, the leaflets ovate, 
membranaceous or chartaceous, 4 to 6 em long, 2 to 3 em wide, somewhat 
shining when dry, the base broad, cordate, the apex shortly and obtusely 
acuminate, or sometimes obtuse or even rounded, the margins entire or 
sometimes with few, small, scattered teeth, especially in the upper part; 
nerves 5 or 7 from the base, rather distinct, anastomosing, the reticulations 
distinct, lax ; stipules about 4 mm long, often 1 cm wide, truncate, clasping 
the stem; tendrils infra-axillary, at least 6 em long, branched. Inflor- 
~ escence axillary, and terminating the short lateral branches, paniculate, 
more or less ferruginous-pubescent, the pedicels 1-flowered. Staminate 
flowers 4-merous, the sepals oblong-lanceolate, obtuse or acute, densely 
ferruginous-pubescent with short hairs on the outside, 10 mm long, 2.5 
to 3 mm wide, rather finely 5- or 6-nerved. Petals none. Stamens many, 
4 to 9 mm long, the connective slender, much produced above the anther, 
on the longer stamens often 3 mm in length, the anthers 1 to 1.5 mm 
long; filaments glabrous. Pistillate flowers larger than the staminate 
ones, the sepals similar but up to 18 mm long, 3 to 3.5 mm wide. Petals 
none. Staminodes slender, linear, about 8, up to 14 mm long, less than 
1 mm wide, some of them frequently antheriferous. Styles covered with 
long white hairs. Mature achenes unknown.
