 sessile.

 2574. Stout, 1 ft. or more high: lvs. broad-ovate or 

 rhombic-ovate, narrowed to both ends, often wavy: fls.

2575. Trillium ercctum (X %). 



Sporting forms are not uncommon. Sometimes forms 

 occur with petiolate lvs. A.G. 1892:206. T. grandiflo- 

 rum is the best and handsomest species for cultivation. 



8. ovatum, Pursh. Much like T. grand if lorum, but 

 the petals narrow-lanceolate or narrow ovate, the sepals 

 usually nearly as long as the petals: plants 1 ft. or less 

 high: lvs. ovate to nearly orbicular, ofteu somewhat 

 rhombic. Calif, to B. C — The Pacific coast representa- 

 tive of T. grand if lor urn.. 



9. erectum, Linn. (T. pindulum, Willd. T. purpu- 

 reum % Kinn. T. fcetidum, Salisb.). Figs. 2575, 2576- 

 Stout, 1 ft. or more high: lvs. broadly rhombic-ovate: 

 pedicel usually bent over or inclined but sometimes 

 erect: fls. brown-purple to greenish purple, the petals 

 usually about 1 in. long, ovate to lanceolate, not much if 

 any exceeding the sepals. Nova Scotia to Manitoba, 

 N Car. and Mo. B.M. 470. L.B.C. 19:1838. F.S. 10:990. 

 Mn. 2:49. G.C. II. 19:605. The fls. of T. erectum are 

 ill-smelling. 



Var. album, Lodd., has white fls. B.M. 1027. L.B.C. 

 19:1850. 



Var. viridifldrum, Hook. Fls. greenish. B.M. 3250. 

 Not known to be in the trade. 



CC. Pedicel generally not exceeding and usually shorter 

 than the flower. 

 d. Fl. declinate under the lvs. 



10. cernuum, Linn. Plant 1 ft. or more high: lvs. very 

 broadly rhombic -ovate, nearly or quite sessile: fls. 

 white, the petals 1 in. or less long, ovate-lanceolate, 

 wide-spreading or reflexed, undulate, equaling or ex- 

 ceeding the sepals. Newfoundland to Ga. and Mo. 

 B.M. 954. Mn. 10:49. 



11. styldsum, Nutt. (T. nervdsum and T. Catesbeei, 

 Ell.). Slender, 12-18 in. high: lvs. ovate-lanceolate, 

 narrow at each end, short-stalked: fls. rose-color, the 

 petals oblong, obtuse or acute, curved, undulate, some- 

 times 2 in. long. N. C. to Fla. 



117 



dd. Flower erect. 



12. pusillum, Michx. Small, usually not 1 ft. high: 

 lvs. lanceolate or oblong, obtuse, sessile: fls. pale flesh 

 color, less than 1 in. long, on a short erect pedicel, the 

 petals lanceolate and exceeding the obtuse sepals. 



T. Govenianum, Wall. A species of temperate Himalaya, 

 little known and described by Hooker as follows: "Lvs. 

 shortly petioled, ovate or ovate-cordate, acute: sepals sub- 

 equal, narrowly linear."— T. obovdtum, Pursh. Founded on a 

 Canadian plant, which lias been referred to T. erectum. Maxi- 

 mowicz keeps it distinct, however, extending its range to 

 Kamtschatka and Japan. It is the T. erectum, var. Japonieum, 

 Gray. According to Watson, the Japanese plant "is distin- 

 guished by a somewhat produced connective [between the an- 

 ther-cells] and very short stigmas." Maximowicz says that the 

 plant differs from T. erectum in the petals being broader and 

 more obtuse and longer than the calyx, the fls. nodding from 

 the first, and the lvs. broader than long, sessile, not attenuate 

 at the base.— T. Smdllii, Maxim. Cue of the T. erectum series 

 (T. erectum, var. Japonicum fiore pleno, GrayJ, of Japan. 

 Fls. smaller than those of T. obovatuin (2 in. across), deep 

 tawny red, the petals not exceeding the sepals, nearly orbicu- 

 lar or obovate. — T. TsehondsHi, .Maxim. About 1 ft. tall: lvs. 

 sessile, broad-ovate or orbicular, somewhat rhombic, acumi- 

 nate: fls. dull purple, ] in. or less across, the petals oblong- 

 lanceolate. According to Hooker, this differs from T. erectum 

 chiefly in the longer filaments." Himalaya to Japan.

TRI6STEUM (name shortened by Linnaeus from Tri- 

 osteospermum, which is from Greek for three bony 

 seeds). CaprifoH&cew. Feverwort. Horse Gentian. 

 A genus of 3 species of coarse perennial herbs, of which 

 2 are American and 1 Himalayan. Stems simple: lvs. 

 rather large, pinnately veined, entire or sinuate: fls. 

 dull-colored, sessile, solitary or in small clusters in the 

 leaf -axils, followed by orange or reddish fruits. 



perfoliatum, Linn. Stem 2-4 ft. high, stout: lvs. 

 ovate, shortly acuminate, narrowed below into conn ate - 

 perfoliate or simply connate base: corolla dull brown- 

 purple. Rich soil. New England and Canada to 111. and 

 Ala. B.B. 3:234. —Is occasionally offered by collectors. 

 It is a weedy plant of very easy cultivation.

TRIPHASIA (triple; alluding to the make-up of the 

 flowers). Hut&cete. A small spiny shrub grown for hedges 

 and for ornament, and sometimes for its small berries, 

 which are used forpreserves: lvs. alternate, sessile, dark, 

 evergreen, trifoliolate, with small ovate lateral leaflets 

 and much larger obovate central leaflet: thorns slender, 

 about % in. long, one or two in the axil of each leaf: 

 fls. white, about % in. long, solitary, or in 3-fld. cymes, 

 axillary; calyx cupulate, 3-4-lobed; petals 3-4, linear- 

 oblong, free, imbricate; stamens 6, free, inserted 

 around a fleshy disk : ovary ovoid, 3-loculed : fr. a small 

 1-3-seeded berry: seeds oblong, exalbuminous, im- 

 mersed in mucilage; testa coriaceous, embryo often 

 with unequal plano-convex cotyledons. Only one 

 species.
