TABERN^EMONTANA 



T^NIDIA 



best ornamental shrubs for subtropical gardens. This 

 species and T. Camassi, referred in this work to Goni- 

 oma, nourish everywhere in Florida from Jacksonville 

 southward. If they receive proper attention, tiny 

 cuttings soon develop into dense, bushy plants 3 to 5 

 feet high, covered with deliciously scented flowers 

 throughout the summer. Indeed the plants are so 

 densely covered with buds and flowers that it is often 

 difficult to find a sufficient supply of cuttings for propa- 

 gation. T. coronaria has larger leaves than T. Camassi 

 and the flowers are much like those of the double white 

 oleander, while T. Camassi has solider and smaller 

 blossoms. Both do well under the same treatment. In 

 order to enjoy the beauty of the East Indian rosebay to 

 its fullest extent, it must be planted in rich, sandy soil, 

 not too wet and not too dry, and in places fully exposed 

 to the sun. Only very strong pot-grown plants should 

 be set out in the garden. This should be done during 

 the rainy season. Avoid breaking the ball in transplant- 

 ing. It is useless to transplant in November, the time 

 when most evergreens and other plants are most suc- 

 cessfully set out. The plants at this season have not 

 time to become established before the first sharp frost 

 comes, and a weakened tabernaemontana is usually 

 killed outright by even a slight frost. Just before 

 Christmas all the plants of this nature (bauhinias, 

 oestrums, Poinciana regia, Tristania conferta, grevilleas, 

 eucalypti, and so on) are banked about 18 inches to 2 

 feet high with dry sand, and they always come through 

 without much damage. In April or even earlier, the 

 banking is taken away and the plants cut back to 

 sound wood. The tabernaemontanas look best in 

 groups by themselves or in front of other glossy leaved 

 evergreens. (H. Nehrling.) 



A. Fls. white. 



coronaria, Willd. CRAPE JASMINE. NERO'S CROWN. 

 A tender shrub, 6-8 ft. high: Ivs. glossy green, oblong 

 to oblanceolate: fls. white, fragrant, 1-2 in. across, in 

 1-8-fld. clusters in the forks of the branches; petals 

 crimped on the margin, whence the common name. 

 Cult, in India but native country unknown. Var. 

 fldre-pleno, with double, somewhat larger, very sweet- 

 scented fls., seems to be far more common in cult. P.M. 

 16:354. B.M. 1865 (as Nerium coronarium). Cult. 

 in the more southern states and also in greenhouses. 

 Also known as Adam's apple and East Indian rosebay. 



AA. Fls. yellow. 



grandifl&ra, Jacq. A small, tender shrub: Ivs. oblong- 

 ovate, sharply acuminate, 2-3 in. long, thick: fls. 

 single, yellow, 1-2 in. long, hi few-fld. clusters; corolla- 

 lobes oval, obtuse, entire. Early fall. Carthagena, 

 Guiana. B.M. 5226. Rarely cult, in the more south- 

 ern parts of the U. S. 



T. Camdssi, Regel. SeeGonioma Kamassi. T. dichdtoma, Roxbg. 

 (Cerbera dichotoma, Lodd.). About 6 ft. high: Ivs. oblong, acute at 

 base, obtuse at apex, 2 J^-5 in. long: cymes terminal, dichotomously 

 branched, many-fld.; fls. slightly odorous, 1 in. long. India. B.R. 

 27:53. L.B.C.16-.1516. H.W. 3, p. 259. T. grandifdlia, Hort., is 

 listed in the American trade, presumably an error for T. grandiflora.

 TACAMAHAC: Populus balsamifera. 



TACCA (Malayan name). Syn., Atdccia. Taccaceae, 

 a family allied to the Dioscorea tribes. Perennial 

 herbs from a tuberous or creeping rhizome, adapted to 

 the warmhouse. 



Leaves radical, large, petioled, sometimes undivided 

 and entire, sometimes variously Ipbed or dissected: fls. 

 at the top of erect leafless scapes in dense umbels, lurid 

 brown or greenish; perianth 6-lobed in 2 rows; stamens 

 6; ovary inferior, 1-celled: fr. globose, ovoid, turbinate 

 or elongated, usually 3-cornered or 6-ribbed, berry-like 

 and indehiscent, rarely finally 3-valved. About 13 

 species in the tropics of both hemispheres. The fl.- 

 cluster is subtended by a few, usually 4, leaf-like or 



colored bracts, and intermixed with the fls. are more or 

 less numerous, long and conspicuous, sterile, filiform 

 pedicels, which usually droop below the fl.-cluster. 

 Taccacese contains only one other genus, Schizocapsa. 



A. Lvs. much lobed. 



pinnatifida, Jack. Tender perennial herb, about 2 ft. 

 high: rootstock globose, becoming 1 ft. through: Ivs. 

 large, usually 3-branched, the divisions pinnately cut or 

 divided, the ultimate lobes sometimes irregular and 

 unequal but usually ovate to lanceolate: fls. greenish, 8 

 lines across, many with the sterile pedicels purplish: 

 berry nearly globular, 1 in. through. Afr., India, and 

 Austral. L.B.C. 7:692. B.M. 7299, 7300. Accord- 

 ing to Von Mueller's Select Extra-tropical Plants, the 

 Fiji arrowroot is prepared from the tubers of this 

 species. The plant thrives even on the sand-shores of 

 tropical countries, and it is not unlikely that it will 

 endure a temperate climate. 



AA. Lvs. not lobed. 



cristata, Jack (Atdccia cristata, Kunth). Rootstock 

 a short conic caudex, marked with If .-scars: Ivs. 1-2 ft. 

 long, oblong, acuminate, dark purplish green: scape 

 longer then the Ivs.: fls. dark purple, 1J/2 in. across, in a 

 somewhat 1-sided umbel, with numerous pale sterile 

 pedicels 8-10 in. long: involucral bracts 4, conspicuous, 

 the 2 inner elliptical, narrowed to a petiole, the 2 outer 

 revolute. Malaya. B.M. 4589. F.S. 9:860-861. Gn. 

 45, p. 415; 49, p. 423. According to Gn. 45, p. 415, 

 it requires good, rich, open soil, with ample drainage, 

 plenty of water, and a stove temperature. In the winter 

 season the plant should be kept in a state of partial rest. 



Chantrieri, Andre. Plant stemless, on a fibrous, red- 

 brown caudex: Ivs. on petioles attaining a length of 28 

 in., which are dilated and imbricated at base, chan- 

 neled and red-brown; blades oval, acute at apex, about 

 20 x 8-10J^ in., brilliant shining green, not symmetri- 

 cal at base: infl. red-brown, brilliant purple, spathes 

 brilliant purple ; fls. about 20, almost 2 in. long. Malaya. 

 R.H. 1901, p. 541. Resembling T. cristata but larger 

 in its proportions and having more numerous long- 

 stalked fls. F.W.BARCLAY 



F. TRACY HUBBARD.! 



TACSONIA (from the Peruvian name of one of the 

 species). Passifloraceze. From Passiflora, Tacsonia 

 differs in having a long-tubular calyx, stamens and 

 petals usually 5, the latter never wanting, corona of 

 tubercles or very short threads, and in a short reflexed 

 crown near the base of the fl.-tube. However, the line 

 of demarcation between the two genera is often not 

 well marked and Harms (Engler & Prantl's Pflanzen- 

 familien) unites Tacsonia with Passiflora. Masters 

 (Trans. Linn. Soc. 27) accepts 25 species of true Tac- 

 sonia, relegating the intermediate forms largely to Pas- 

 siflora. Other species have been discovered subse- 

 quently. The Tacsonias are all S. American, inhabiting 

 the Andes. They are tendril-climbing shrubs or herbs, 

 requiring the treatment given passifloras. Tacsonias 

 are cult, freely in the open in Cent, and N. Calif. T. 

 manicata (Passiflora manicata) is a common and strik- 

 ing red-fld. tall climber in S. Calif. 



In this work, following Engler & Prantl and also 

 Hooker, the Tacsonias are described under Passiflora. 



T^ENIDIA (Greek, making reference to the very 

 small ribs of the fr.). Umbelliferse. One species, a 

 slender smooth glaucous perennial of E. Canada and 

 U. S., T. integerrima, Drude, formerly known as Pirn- 

 pinella integerrima, Gray, and Zizia integerrima, DC. 

 It has little value to the horticulturist, although inter- 

 esting to the collector of native plants for the hardy 

 border. It is erect, 2-3 ft., slender, open-branched, 

 with long-rayed umbels of small yellow fls. in spring 

 and early summer: Ivs. ternately 2-compound, the Ifts. 

 oval to lanceolate, entire, nearly or quite obtuse.
