TRITONIA 



TROLLIUS 



nently if ^'iveu protection of mulch in cold climates. As 

 far north as New York ami Mass., however, they are usu- 

 ally best wintered in damp (not wet ) earth indoors. The 

 best known kinds are T. crocofntue flora and T. Fottsii. 

 Most of the Latin names in catalogues belong to these, as 

 .■<iil />lnu-e(f, Tigridia j'l/rani i(hi lis, 

 (/■nnuUfJora, elegaiis, fforibituda. 

 To gardeners, Tritonias are usually 

 known as Montbretias. Garden Trl- 

 tonias grow 1 ft. or more tall, pro- 

 ducing several to many showy flow- 

 ers of a yellow, orange or red color, 

 ■uid bearing several stiftish linear 

 or sword-shaped 

 leaves. Cornis 

 small, covered 

 with strongly 

 reticulated 

 sheaths or tu- 

 nics. The peri- 

 anth is tuliular, 

 with a s])read-

ing limb of obnvate or oblong, 

 nearly equal segments. The 

 stamens are 3, inserted in the 

 perianth-tube, with mostly ver- 

 satile anthers and filiform fila- 

 ments. The pistil has a 3- 

 loculed ovary, filifoi-m 3- 

 branched style, ripening into a 

 3-valved capsule.

 These plants are usually treated as greenhouse bulbs 

 in the North.

 base) as long as the tube and anthers just protruding 

 from the tube. Cape Colony. B.M. 7280. -Can l>e left

cemes, and few or several firm narrow Ivs.: fl. about

 much branching, erect plant 3—4 ft. high, with several 

 or many sword-shaped Ivs., and loose, more or less dis- 

 tichous racemes: fls. 2 in. across, orange-crimson, with 

 a slender curved tube nearly or quite equaling the ob- 

 long spreading segments. R.H. 1882:124. Gn. 25, p. 363;

 (into England) in 1847, and Trilotiia Poftsii (into Scot- 

 land) in 1877 by G. H. Potts. Victor Lemoine, Nancy, 

 France, hybridized the two, and the product, T. crocos- 

 mwflora, bloomed in 1880. This hybrid is now the most 

 popular of Tritonias (or Montbretias).

 TRbLLIUS (old German trol , something 

 round; in allusion to the shape of the flow- 

 ers. ) J^a)iuncutdcea?. Globe Flower. A 

 group of neat, hardy, herbaceous perennials 

 of about 10 species, mostly found in marshy 

 places, of the north temperate zone. Roots 

 fibrous, thickened: lvs. palmately divided or 

 lobed: fls. large, solitary, yellowish or pur- 

 plish; petals 5 to many, small, unguiculate, 

 with a nectariferous pit at the base of the 

 blade: stamens many: carpels 5 to many, ses- 

 sile, many-ovuled : follicles in a head. Plants 

 of this genus grow freely in a mixture of 

 sandy loani and peat, and in rather damp 

 situations. They may be increased either by 

 seeds, or by dividing the old plants; bnt the 

 young plants groM' slowly at first, and will not 

 flower before the second season from seed.
