546 CLIL TRILLIACEZ. ~ ‘Trriiiem. 
1. T. sessite. Sessile-flowered Trillium. 
Lws. broad-ovate or suborbicular, rather acute, sessile ; {a sessile, 
erect; sep. erect, ovate-lanceolate or lanceolate, acute; pet. linear-lanceolate, 
urple, a third longer than the sepals; anth. long, erect.—A small species in 
ertile soils, Middle, Western (Clark! Plwmmer!) and Southern States. Rhi- 
zoma horizontal, thick. Stem 6—8’ high, slender. Leaves rather thick, 14—2}’ 
by 1—2’, smooth and entire. Sepals green, about 8” by 3”, the petals narrower 
and much longer, dark purple. Apr. May. 
2. T. rEcurvatum. Beck. 
Lws. ovate or obovate, attenuated to a petiole, acute; 7. closely sessile ; 
pet. lanceolate-ovate, very acute, attenuate at base, erect, as long as the recurved 
sepals—A small Trillium quite distinct, although allied to the last, in shady 
woods, Wis., Lapham! Ill, Jenney! Mo., Beck. Stem 8—10’ high, rather thick. 
Leaves 2—22’ by 14—2’, with distinct, short petioles. Petals purple, and with 
the green, reflexed sepals about 1’ long. May. 
3. T. eryTHROcARPUM. Michx. (T. pictum. Ph.) Smiling Wake-robin. 
Las. ovate, acuminate, rounded at base, abruptly petioled; ped. erect; pet. 
lanceolate-ovate, recurved, twice as long as the sepals——Can.to Ga. A beauti- 
~fal flower, adorning our woods in May and June. Stem 8—12’ high, witha 
whorl of 3 broad-ovate leaves at top. These are 3-veined, rounded at base, long 
acuminate, 3—4’ long, 3 as wide, petiole 2—3” long. Flower nearly erect. 
Petals wavy at the edges, white, finely radiated with purple lines at base. The 
root is considered medicinal. 
B. Cleavelandicum. Wood. (T.Cleavelandicum. Swallow!) Sep. developed 
into leaves, which are but little smaller than the true leaves; pet. 6, the 3 outer 
but partly colored. Otherwise as in a.—Brunswick, Me.! This is probably a 
metamorphosis; but Mr. S. has gathered it three years in succession, and also 
finds it thus far unaltered when cultivated from the root. Its claims to the 
rank of a species must be tested by plants reared from the seeds. (Dr. T. 
Rickard comm.) 5 
4. T. pusittum. Michx. (T. pumilum. Pi.) 
Lrs. oval-oblong, obtuse, sessile ; ped. erect; pet. scarcely longer than the 
calyx.—Penn., Muhlenberg. A very small species. Petals flesh-colored. This 
plant appears to be lust to the later botanists. 
5. T. nrvate. Riddell. Snowy Trillium. 5 
Rt. tuberous, premorse; st. low; lvs. ovate or oval, rather obtuse, distinctly 
and abruptly petiolate; f#. short, pedunculate, erect; -pet. spatulate-obovate, 
obtuse, white, one-third longer than the calyx.—The smallest species here 
described, in stony or dry fields, Ohio, Clark! Wis., Lapham! Stem 2—4 high, 
from a thick, tuberous root. Leaves 8—18” by 5—12”, petioles 2—4”, about 
equaling the peduncle. Sepals green, much narrower than the snowy petals 
which are about 8” by 4”. Mar. Apr. 
6. T. penpttum. Muhl. (T. cernuum. Bart., Ph., Gc.) Drooping Tril- 
livm.—Lvs. suborbicular-rhomboidal, abruptly acuminate, shortly petio- 
liate; fl. cernuous, on a recurved peduncle——A large species, with a small 
flower, Mid. and W. States! Stem slender, 10—15/ high. Leaves3—5’ diam., 
nearly round, on petioles 1” long. Flower white, pendulous beneath the leaves. 
Peduncle 1—2}/ long. Sepals green, oblong-lanceolate, acuminate, 1’ long. 
Petals oblong-ovate, acute, 1}/ by 3’, white. Stigmas erect, recurved at top, 
lower part styloid (or styles 3, t, with recurved stigmas!). May, Jn. 
7. T.eRecTtuM. (T. atropurpureum. Curt.) Bath Flower. 
Lvs. rhomboidal, acuminate, sessile; ped. inclining; fl. nodding; pet. 
scarcely longer, but much broader than the sepals.——A conspicuous plant in 
woods, of fine appearance, but of an intolerably offensive odor. At the top of 
the stem, which is a foot high, is a whorl] of 3 leaves which are 3-veined, 3—5’ 
long, of equal width, and a single, nodding flower, on a nearly erect peduncle. 
Petals broad-ovate, an inch long, twice as wide as the sepals and of a dusky 
purple, greenish outside. May. *
