TRIPHASIA 



TRITELEIA 



in greenhouses. Produces an abundance of elliptical or 

 nearly globular, gland-dotted red berries about %-% in. 

 across. They are sweet and agreeable and are said to 

 be delicious when preserved. In trade catalogues the 



2577. Triphasia aurantiola (X 



names Triphasia anrantiola and T. trifoliata are 

 sometimes erroneously applied to the hardy trifoliolate 

 orange (Citrus trifoliata). In the U. S., little known 

 except in S. Fla. It withstands some frost.

TRlPSACUM (Greek, tribo, to rub or thresh; probably 

 alluding to the ease with which the fertile spike can be 

 broken up). Oramlnece * Species 2 or 3, of the wanner 

 parts of North America, one extentfing north to central 

 U. S. and in many places furnishing considerable na- 

 tive fodder. Fls. monoecious, in the same spike, the 

 staminate above; spikes terminal and axillary; stami- 

 nate spikelets 2-fld., in pairs at each joint; pistillate 

 single, 1-fld., imbedded in each joint of the rachis, so 

 that the smooth cartilaginous axis and the outer glume 

 form a nearly cylindrical mass. At maturity the pistil- 

 late spikes separate into the joints. 



dactyloides, Linn. ( T. violdceum and T. Ddctylis of the 

 trade). GAMA GRASS. SESAME GRASS. Culms in bunches, 

 4-7 ft. : spikelets 2-3 at summit and often single from the 

 upper axils. Moist soil, Conn., 111., Kans. and south- 

 Ward. A wild fodder grass, sometimes cultivated for 

 the same purpose and also in gardens as a curiosity. 

 Raised from seed, or more certainly from cuttings of 

 the rootstocks. A> g. HITCHCOCK. 



TEISTAGMA (Greek, three drops; alluding to the 

 three nectar glands of the ovary). Including StepTia- 

 nolirion. Lilidcece. A genus of 3 species of bulbous 

 plants from Chile. Radical Ivs. few, narrowly linear; 

 scape naked, bearing rather numerous salver-shaped 

 pedicellate fls. in an umbel: perianth-tube cylindrical, 

 sometimes with a crown in the throat; lobes 6, spread- 

 ing, nearly equal; stamens 6: ovary sessile, 3-loculed, 

 ovoid. Fall-blooming bulbs. 



nivale, Poepp. (Milla nivdlis, Baker). Lvs. 6-9 in. 

 long, about 2 lines wide ; scape slender, about 1 ft. 

 long : fls. 1 in. long, 2-8 in an umbel, the segments 

 linear and greenish; crown none. Offered by Dutch 

 bulb growers. 



T. narrissoldes, Benth. & Hook., does not appear to be in the 



Amer. trade. It is 1 ft. or more high, with short narrow-linear 

 Ivs., and white fls. bearing a bright orange narcissus - like 

 crown of !i-6 broad unequal more or less connate scales.

TRISTANIA (in honor of Jules M. C. Tristan, 1776- 

 1861, a French botanist). Myrtdcece. A small genus 

 of subtropical evergreen Australasian trees or small 

 shrubs. Lvs. alternate or rarely opposite, somewhat 

 whorled: fls. axillary, pedunculate, cymose, often fra- 

 grant; bracts obovate or caducous ; calyx-tube turbin- 

 ate-campanulate, lobes 5; petals 5, spreading; stamens 

 numerous, united in bundles opposite the petals: cap- 

 sule 3-loculed, many-seeded, partly exserted or inclosed : 

 seeds numerous, wingless, usually linear-cuneate. Cul- 

 tivated as greenhouse shrubs in N. Europe; hardy in 

 Calif, north to San Francisco, also in Fla. Propagated 

 by half-ripened cuttings in sand under glass, or by 

 seeds. 



conferta, R. Br. (Lophostemon arborescent, Schott. ). 

 BRISBANE Box. Fig. 2578. An umbrageous tree attain- 

 ing 150 ft.: young shoots and calyx hoary-pubescent: 

 Ivs. 3-6 in. long, ovate-lanceolate, glabrous, usually 

 crowded at the ends of the branches and apparently 

 verticillate : ids. mostly on the branches well below 

 the Ivs.; petals about % in. long, white and spotted, 

 fringed. Queensland. B.R. 22:1839 (as T. macro- 

 phylla). A handsome evergreen shade tree, valuable 

 for avenues in hot, dry regions, as it withstands great 

 drought; it also produces timber valued for strength 

 and durability. Much grown in New South Wales as 

 a boulevard tree. Hardy in middle California, with- 

 standing an exceptional temperature of 26 Fahr. at 

 Berkeley. JOSEPH BURTT DAVY. 



TRITELEIA (three and complete; referring to the 3- 

 merous fls.). LilidcecK. Triteleia has been referred to 

 Milla and Brodiffla; but when the group is restricted to 

 the South American species, it seems to be advisable to 

 keep it distinct. In Brodiasa proper the pedicels are 

 articulated at the apex; in Milla and Triteleia they are 

 not articulated. In Milla the stamens are inserted in 

 one series in the throat of the perianth ; in Triteleia 

 they are distinctly in two series in the tube of the peri- 

 anth. See Brodicea and Milla. 



About 16 Triteleias are known (see Baker, G.C. III. 

 20, p. 459). These are of two series, those with .peri- 

 anth-tube usually as long as the segments, and those 

 with tube shorter than segments. To the former sec- 

 tion belongs the common T. uniflora, the only species 

 in general cultivation. The species are native to the 

 Andes and Argentina as far east as Buenos Ayres. 

 They are all low grass-leaved bulbous plants, hardy or 



2578. Tristania conferta (X %). 



half-hardy, useful for planting in the border or for 

 spring blooming in pots. Sometimes the odor is un- 

 pleasant. 



unifldra, Lindl. (Milla unifldra, Grah. Broduea uni- 

 flora, Baker). SPRING STAR-FLOWER. Fig. 2579. Lvs.
