obtuse. N. C., Tenn., and Ga., in the mountains. 

 Allied to T. erectum. 



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

 Ivs. lanceolate or oblong, obtuse, sessile: fls. pale flesh- 

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

 als lanceolate and exceeding obtuse petals. Pine lands, 

 N. C., S. C. 



13. cernuum, Linn. Plant 1 ft. or more high: Ivs. 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 

 exceeding the sepals. Newfoundland to Ga. and 

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



14. styldsum, Nutt. (T. nervbsum, Ell., and T. 

 Ctiesbsti, Ell.). Slender, 12-18 in. high: Ivs. ovate- 

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

 color, the petals oblong, obtuse or acute, curved, undu- 

 late, sometimes 2 in. long. N. C. to Fla. 



T. Govenidmum, Wall. A species of Temp. Himalaya, little known 

 and described by Hooker as follows: "Lvs. shortly petioled, ovate 

 or ovate-cordate, acute: sepals subequal, narrowly linear." T. 

 obovatum, Pursh. Founded on a Canadian plant, which has been 

 referred to T. erectum. Maximowicz keeps it distinct, however, 

 extending its range to Kamchatka and Japan. It is the T. erectum 

 var. japonicum, Gray. According to Watson, the Japanese plant 

 "is distinguished by a somewhat produced connective (between the 

 anther-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 Ivs. broader than long, sessile, not attenuate at the base. T. 

 Smdllii, Maxim. One of the T. erectum series (T. erectum var. 

 japonicum flore-pleno, Gray), of Japan. Fls. smaller than those of 

 T. obovatum (2 in. across), deep tawny red, the petals not exceeding 

 the sepals, nearly orbicular or obovate. T. Tschonoskii, Maxim. 

 About 1 ft. tall: Ivs. sessile, broad-ovate or orbicular, somewhat 

 rhombic, acuminate: fls. dull purple, 1 in. or less across, the petals 

 oblong-lanceolate. According to Hooker, this differs from T. erec- 

 tum chiefly in the longer filaments. Himalaya to Japan.

F. TRACT HTJEBARD.! 



TRIOSTETJM (name shortened by Linnaeus from Tri- 

 osteospermum, which is from Greek for three bony 

 seeds'). Caprifoliacese. FEVERWORT. HORSE GENTIAN. 

 Coarse hardy perennial herbs, glabrous or glandular- 

 pilose: sts. rather simple, terete: Ivs. opposite, sessile, 

 rather fiddle-shaped or obovate, entire: fls. usually 

 axillary, solitary or clustered, dirty white, yellow, or 

 purple; calyx-tube ovoid, limb 5-lobed, persistent; 

 corolla tubular-campanulate, base of tube gibbous, limb 

 oblique, lobes unequal; stamens 5; disk small, swollen; 

 ovary 3-5-celled : berry fleshy or leathery, 2 (rarely 3-5)- 

 celled, 2-3-seeded. About 8 species, N. Amer., Hima- 

 layas, and China. 



perfoliatum, Linn. St. 2-4 ft. high, stout: Ivs. ovate, 

 shortly acuminate, narrowed below into connate-per- 

 foliate or simply connate base: corolla dull brown- 

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

 Ala. B.B. 3:234. Sometimes offered by collectors. It 

 is a weedy plant of very easy cult. p. yf. BARCLAY. 



TRIPETALEIA (Greek, three and petals). Ericacex. 

 Two species of Japanese shrubs with deciduous alter- 

 nate, short-petioled entire Ivs. and white or pinkish fls. 

 in terminal racemes or panicles: sepals and petals 3; sta- 

 mens 6, shorter than the petals, the anthers opening 

 with a longitudinal slit; ovary 3-celled, superior, short- 

 stalked; style slender, curved: caps, septicidal, many- 

 seeded. Closely allied to Elliottia, but easily distin- 

 guished by its 3-merous fls. T, paniculata has proved 

 hardy at the Arnold Arboretum ; it seems to like humid, 

 but well-drained, peaty or sandy soil and will probably 

 grow best in a rockery in a partly shaded place. The 

 second species was only recently intro. and has not yet 

 been tested. Prop, is by seeds treated like those ^of 

 rhododendron and probably also by cuttings. T. panic- 

 ulata, Sieb. & Zucc. Shrub, to 6 ft. : Ivs. short-petioled, 

 rhombic or rhombic-obovate, acute, cuneate at the base, 

 glabrous except a few hairs on the midrib beneath, 

 1-2^ in. long: fls. in panicles 2-4 in. long, white, tinged 

 pink, H m - long) style exserted; bracts subulate. Aug.
