PELARGONIUM tortuosum. 
Twisted-petaled Stork's-bill. 
P. tortuosum, foliis cordatis subseptemlobis planis mar- 
gine undulatis acute dentatis utrinque pilosis multi- 
nerviis, stipulis ovato-lanceolatis acuminatis, umbel- 
lis multifloris, petalis tortuosis margine revolutis, 
tubo nectarifero calyce acuminato multo breviore. 
Stem frutescent, erect, branching, thickly clothed 
with unequal spreading villous hairs, as are the petioles, 
peduncles, and calyx. Leaves cordate, scarcely acute, 
rather broader than long, generally seven-lobed, flat, 
with undulate margins, sharply toothed with short teeth, 
hairy on both sides, many-nerved underneath, and fur¬ 
rowed on the upper side; lobes rounded, and generally 
touching each other, sometimes slightly overlapping. 
Petioles a little flattened on the upper side, and rounded 
on the lower, rather slender. Stipules broadly lanceolate, 
taper-pointed, very hairy, and fringed. Umbels nume¬ 
rous, many-flowered. Peduncles cylindrical, rather slen¬ 
der. Involucre of 6 or 7 broadly lanceolate, taper-point¬ 
ed bractes, that are unequal in size, and generally lon¬ 
ger than the nectariferous tube. Pedicles very short. 
Calyx 5-cleft, the segments very long, lanceolate, ta¬ 
per-pointed, spreading, or the points a little reflexed, 
about half as long again as the nectariferous tube, 
sometimes twice the length. Nectariferous tube flattened 
on each side, and gibbous at the base, villosely hairy. 
Petals 5, more or less twisted and rolled back at the 
margins; the two upper ones broadest, obovate, taper¬ 
ing to the base, of a bright lilac, with a dark purple
