some. Never allow the plants to become pot-bound 

 until the size desired for flowering is attained. Give 

 strict attention to keeping the plants in shape, by pinch- 

 ing the strong shoots, and tying them to the outer edge 

 of the plants, allowing the weaker ones to grow, and fill 

 up the middle of the plant. In summer the plants may 

 be placed out-of-doors, and plunged to the rim of the 

 pot, in a bed of ashes; but never allow the sun to strike 

 them directly, as it will disfigure the foliage. These 

 plants are excellent for exhibition purposes and con- 

 servatory decoration. The species T. elegans and T. 

 semidecandra are worthy of general cultivation. (George 

 F. Stewart.) 



semidecandra, Cogn. (Lasidndra macrdntha, Lind. 

 & Seem. Pleroma macrdnthum, Hook.). Fig. 3807. A 

 tender shrub: Ivs. ovate or oblong-ovate, 2-6 in. long, 

 round at the base, short-petioled, densely setose above, 

 villous beneath, not foveolate, 5-nerved or 3-nerved: 

 bracts broadly suborbicular, somewhat rounded at the 

 apex and shortly apiculate, margin not translucent : fls. 

 reddish purple to violet, often 5 in. across, solitary and 

 terminal or 1 fl. terminal and 2 in the upper axils on 

 the branchlet; stamens purple; style setulose. Brazil.

 flowers more freely than the type when small . Lasidn- 

 dra, or Pleroma splendens, Hort., should be compared 

 with this. The fls. of T. semidecandra last but a day 

 or so, but the flowering season lasts for several weeks. 

 Plants may also be used for summer bedding. They 

 are seldom out of bloom. The species is much esteemed 

 in Fla., where it makes a showy shrub 8 ft. high. It 

 endures a few degrees of frost with impunity, and even 

 if cut down it sprouts readily. 



elegans, Cogn. (Pleroma elegans, Gardn.). Tender 

 shrub, 3-6 ft. high: Ivs. rigid, fragile, oblong or ovate- 

 oblong, 3-nerved: fls. purple, \Yi in. across; calyx more 

 or less armed with rigid spreading bristles which are 

 thickened at the base. Brazil. B.M. 4262. P.M. 15:27.

There is a plant offered in the trade under the name of PlerAma 

 cdndidum, Hort. Bull, described as being a shrub with dark green 

 ovate-lanceolate Ivs., densely silky-hairy, the 5 longitudinal veins 

 Very prominent beneath : fls. snowy white, about 1 %-l % in. across, 

 borne in loose terminal heads. Said to have been intro. from S. 

 Austral. As there are no Tibouchinas known outside of S. Amer. it 

 is not likely that this is correctly placed in Pleroma; the proper 

 identification of the plant is at present impossible. T. lepiddta, 

 Baill. (Lasiandra lepidota, Naud.), is a plant which has been much 

 confused and is still uncertain. F. W. 1874 : 289. There is a plant 

 at least formerly cult, under the name of Plerdma sarmentdsum, 

 Hook. Small villous shrub with the branches and branchlets sar- 

 mentose: Ivs. short-petioled, ovate or oblong, acute, base rounded or 

 cordate, 7-nerved, pilose: fls. blue, about 2 in. across; calyx-tube 

 obovoid or subglobose, densely tomentose; petals cuneate-obovate. 

 Peru. Its position and name in Tibouchina are uncertain. B.M. 

 5629. F.W. 1869:225.?'. stenocdrpa, Cogn. Shrub with acutely 

 4-angled branches whieh are sometimes somewhat winged: Ivs. 

 short-petioled, usually oblong, base generally short-attenuate, 5- 

 nervea, silky villous: fls. many in a terminal panicle, usually rather 

 large, purple or violet-purple; calyx-tube campanulate; petals 

 narrowly obovate-cuneate. Brazil. p TRACY HtJBBARD . t 



TIEDEMANNIA: Oxypolis. 



TIGER-FLOWER: Tigridia. T. Lily: Lilium tigrinum. 



TIGRIDIA (tiger-like, referring to the peculiarly 

 marked flowers). Iridacese. Bulbous plants, grown in 

 the greenhouse and also making very showy summer- 

 blooming subjects. 



Bulbs tunicated: st. erect, mostly unbranched, 1- 

 lYi ft. tall, with a few narrow plicate Ivs. at the base 

 and 2 or 3 smaller ones higher up: spathes 1 or 2, leaf- 

 like, each bearing 1 or few blossoms: fls. in shades of 

 yellow, orange or purplish, variously spotted, often very 

 showy; perianth wide-spreading, with no tube, the 

 segms. 6, in 2 dissimilar series, connivent into a broad 

 cup at the base; stamens 3, the filaments united into a 



long cylindrical tube including the style; pistil with 

 3-loculed ovary, long style with 3 2-parted branches. 

 About 13 species from Mex., Cent. Amer., Peru, and 

 Chile. T. Pavonia, from S. Mex., was in cult, in Eu. 

 in the 16th century. L'Obel described it in 1576. The 

 younger Linnaeus referred it to the genus Ferraria, and 

 some of the tigridias are yet cult, under that name. 

 Ferraria, however, is a S. African genus, and all the 

 parts of the perianth are nearly equal. T. Pavonia is 

 cult, in many forms, and is the only common species in 

 gardens. The fls. of all tigridias are fugitive, lasting 

 only for a day. 



Tigridias are tender "bulbs" requiring the treatment 

 given gladiolus. Plant in well-prepared soil when set- 

 tled weather comes, 2 to 3 inches deep and 4 to 8 inches 

 apart. The principal blooming period is July and 

 August. Allow the corms to remain in the ground until 

 danger of frost approaches, then store in a dry place 

 where dahlias or gladioli 

 will keep. See that the 

 corms are dry before being 

 placed in storage. Propa- 

 gation is by cormels and 

 seeds. The best colors are 

 secured in warm weather. 



A. Fls. large (often 4 in. or 

 more across)', the 2 

 rows of perianth- 

 segms. very dissimi-

 Erect, usually unbranched, 

 l/ / 2-2}/2 ft. tall, glabrous, 

 with several sword-shaped, 

 strongly plicate long- 

 pointed Ivs., the spathe- 

 Ivs. 3-5 in. long: fls. pro-

 very large and showy, in 

 some forms 5-6 in. across, 

 oddly marked, with a

 spreading limb formed 

 by the obovate outer 



segms. which are bright red on the limb, and purple, 

 yellow, or red-spotted on the claw; inner segms. pan- 

 duriform (fiddle-shaped), about half the length of the 

 outer ones, the blade ovate-acute, orange-yellow, and 

 copiously spotted. Mex. and Guatemala. B.M. 532 

 (as Ferraria Tigridia). I.H. 38:142. G.C. III. 55, 

 suppl. Feb. 21. Gn. 64, p. 56. G.W. 11, p. 290; 14, 

 p. 674. R.B. 26:73. Var. conchiflora, Hort. (T. 

 conchiflora, Sweet), has bright yellow fls. Var. Wat- 

 kinsonii, Hort. (var. aurea, Hort. T. conchiflora 

 Wdtkinsonii, Paxt.). Raised from seeds of var. con- 

 chiflora pollinized by T. Pavonia, before 1840, by J. 

 Horsefield, Manchester, England. Horsefield is quoted 

 as follows by Paxton: "In habit and strength this 

 hybrid resembles T. Pavonia, the male parent; but in 

 color and the markings of the flower it resembles T. 

 conchiflora, the female parent; the large outer sepals, 

 however, are of a very deep yellow, inclining to orange, 

 and sometimes elegantly streaked with red lines ; whilst 

 the spotted center equals, if not surpasses, the brilliancy 

 of either of the species. One of its greatest merits is 

 being so free a bloomer, and as easy to cultivate and 

 increase as T. Pavonia, whereas T. conchiflora is rather 

 delicate, increases slowly, and is easily lost." Dutch 

 bulb-dealers may still offer it. P.M. 14:51. Var. alba, 

 Hort., has white fls., with red spots in the throat. G.L.
