 Ivs. and loose 6-15-fld. racemes: fls. bright red, with 

 oblong segms. (the 3 lower ones yellow-blotched at the 

 base) as long as the tube and anthers just protruding 

 from the tube. Cape Colony. B.M. 7280.- Can be left 

 in the open as far north as Mass., if well protected, but 

 are usually safer if taken up.

 Crocosmia aurea was 

 intro. (into England) 

 in 1847, and Tritonia Pottsii (into Scotland) in 1877 by 

 G. H. Potts. Victor Lemoine, at Nancy, France, hybrid- 

 ized the two, and the product, T. crocosmseflora, 

 bloomed in 1880. This hybrid is now the most popular 

 of tritonias (or montbretias). 



The following varieties are offered in the trade under 

 the generic name Montbretia; as they are mainly color- 

 forms it seems inadvisable to make new combinations 

 for them, and they are accordingly retained under the 

 trade name. Montbretia crocosmaeflora var. aurantiaca, 

 Hort. (M. aurantiaca, Hort.), has deep orange fls. Var. 

 californica, Hort. (M. califdrnica, Hort.), has golden 

 yellow fls. Var. germania, Hort. (M. germania, Hort.), 

 has glowing orange-scarlet fls., with blood-red throats. 

 Var. pyramidalis, Hort., is offered in the trade. Var. 

 specidsa, Hort. (M . specidsa, Hort. T. specidsa, Hort.), 

 is said to have close spikes of rich deep yellow fls., the 

 reverse side apricot. J.H. III. 48:391. 



Some of the following plants occur in the trade under Montbretia 

 and have never been transferred to Tritonia. They are little known 

 botanically and m some cases are probably hybrids or forms of T. 

 crocosmffiflora and are here listed as Montbretias as signified by the 

 M. before the specific name. T. aiirea, Pappe (M. aurea, Hort.). 

 See Crocosmia aurea. T. crispa, Ker-Gawl. Fl. whitish or pale 

 pink, with oblong, obtuse segms. and with crisped Ivs. B.M. 678 

 T. deusta, Ker-Gawl. Differs from T. crocata in having a purple- 

 black blotch on the claw of the 3 outer segms. B.M. 622. M. 

 elegans, Hort., has yellow and apricot fls.; possibly a form of T. 



3852. Tritonia crocosmseflora. ( X l /Q

 oblong and the 3 lower ones with a callus in the throat: Ivs. very 

 short. B.R. 747. M. germdnica, Hort., is offered in the trade as a 

 form with scarlet fls., shaded with orange, 3 in. across. T. hyalina,

 rowed at the lower part into a claw with hyaline margin. B.M. 704 

 (as T. fenestrata). T. lineata, Ker-Gawl. Fls. white or pink, with 

 short oblong segms. and protruding anthers, of the shape of gladiolus 

 fls. B.M. 487 (as Gladiolus lineatus). M. Prometheus, Hort., is a 

 horticultural form which grows up to 4 ft. high, with branching 

 spikes of rich orange or orange-red fls., 3^2 in. across, their center 

 crimson. Gn. 71, suppl. Jan. 19. G.M. 49:815. M. rdsea, Hort., is 

 offered in the trade as a form growing 3 ft. or more high with long 

 arching spikes of rose or bright salmon-rose fls. T. scittaris, Baker. 

 Small and slender: fls. pink, with wide-flaring narrow segms., ixia- 

 like. B.M. 629 (as Ixia polystachya). T. securtgera, Ker-Gawl. 

 Lvs. short: fls. red or copper-colored, the 3 lower segms. with a callus 

 on the claw. B.M. 383 (as Gladiolus securiger). T. unduldta, 

 Baker. Lvs. short and narrow, much crisped: fls. pink, with oblong 

 equal segms. B.M. 599 (as Ixia crispa). T. viridis, Ker-Gawl.

TRIUMFETTA (named for Giov. B. Trionfetti,

 Ivs., few or densely fasciculately cymose; sepals 5; petals 

 5, rarely none; stamens numerous; ovary 2-5-celled, 

 cells 2-ovuled: caps, small, subglobose, spiny or bristled. 

 About 100 species, widely dispersed over the world. 

 Several species have been intro. abroad but none of 

 them is cult, to any extent. 



TROCHETIA (named for R.I.G. du Trochet, 1771- 

 1847, Paris). Sterculiaceae. Shrubs or trees, evergreen, 

 grownin the warmhouse or coolhouse. Lvs. entire, leath- 

 ery: peduncles axillary, 1-3-fld.: fls. usually pendulous, 

 rather large; calyx 5-parted, leathery; petals 5, flat, 

 broad, and persistent; staminal column short, bearing 

 5 ligulate staminodia; anthers 10, 15, or 20, stipitate;

 loculicidally 5-valved. About 6 or 7 species, natives of 

 Mauritius, St. Helena, and Mascarene Isls. 



Blackburniana, Bojcr. Shrub or small tree '.branches, 

 petioles, and ribs of the Ivs. rusty-scurfy with stellate 

 hairs: Ivs. long-petioled, elliptic- or obovate-oblong,

TROCHODENDRON (Greek, wheel and tree, allud- 

 ing to the appearance of the fls., the anthers of the 

 numerous spreading stamens forming a ring.). Trocho- 

 dendrdceee. Evergreen tree with aromatic bark and 

 foliage, with alternate or whorled long-petioled Ivs. and 

 small fls. in terminal upright racemes; fls. long-pedi-

 ments slender: carpels 6^-10 in one whorl, connate below, 

 with short linear spreading styles: fr. consisting of 6-10 

 follicles inserted below in the fleshy receptacle, dehiscent 

 at the apex, with several linear seeds in each carpel. The

 middle and southern Atlantic states and for Calif . T.
