One or two species, with white flowers, 

 are grown in this country. [M. T. AL] 



TRIZEUXIS. An epiphytal genus of 

 orchids, belonging to the tribe Vandece, 

 containing one species, an inhabitant of 

 Tropical America and Trinidad. It bears 

 distichous recurved acute laterally com- 

 pressed fleshy leaves, which are grooved 

 at the base; and small greenish flowers, in 

 a panicle arising from the axils of the 

 lower leaves, collected into heads at the ex- 

 tremities of the branches of the panicle. 

 The genus is remarkable in having the lip 

 superior— that is, with the parts of the 

 flower in their proper position, the ovary 

 not being twisted as in the generality of 

 orchids. [W. B. H.] 



TROCHETIA. The name of a genus of 

 small shrubs, natives of Bourbon and 

 Madagascar. They are covered with brown 

 scales, and have entire feather-veined 

 leaves, and axillary flower-stalks. The 

 calyx is five-parted ; petals five, deciduous ; 

 stamens numerous, combined below into a 

 tube, some of them sterile, strap-shaped, 

 entire or cleft, alternating with the fertile 

 ones; ovary sessile, five-celled, the style 

 thread-like; fruit capsular five-celled five- 

 valved, thevalves bearing numerous round- 

 ish seeds on their centre. [M. T. M.] 



TROCHLEAR. The same as Pulley- 

 shaped. 



TROCHOCARPA. New Holland shrubs 

 or small trees of the family Epacridacece. 

 The leaves are on short stalks, the flowers 

 white or yellow, placed on terminal or 

 axillary spikes. At the base of the five- 

 cleft calyx are two small bracts : the 

 corolla is funnel-shaped, its limb divided 

 into five spreading hairy segments; the 

 stamens are concealed within the corolla, 

 the anthers being pendulous; and a flve- 

 lobed cup-like disk surrounds the ten- 

 celled ovary, in each compartment of 

 which is a single seed. The fruit is suc- 

 culent, with ten one-seeded stones, which 

 ultimately fall away one from the other. 

 The name is derived from the Greek tro- 

 chos ' a wheel ' and karpos ' fruit,' indi- 

 cating the radiated arrangement of the 

 cells of the fruit. T. lauriria is a very 

 handsome greenhouse shrub. [M. T. MJ 



TROCHODEXDROX. A genus of Mag- 

 noliaceae, comprising a Japanese tree, 

 whose leaves are described as being ar- 

 ranged in whorls, and as lasting green for 

 three years, each whorl being separated by 

 a rather long interval from its neighbour. 

 On this space the perulas or bud-scales 

 remain, and do not, as in ordinary cases, 

 fall off. The leaves themselves are stalked, 

 somewhat rhomb-shaped, cuspidate, and of 

 a thick texture. The clusters of flowers are 

 terminal, and the pedicels are provided 

 with a small linear bract at the base. The 

 flowers themselves have no calyx or co- 

 rolla, but a crowd of deciduous stamens, 

 a five to eight-celled ovary with several 

 ovules in each cell, and five to six styles. 

 The fruit is capsular, surmounted by the 



persistent styles, dividing when ripe into 

 five to eight valves; seeds pendulous. 

 The name is derived from the Greek tro- 

 chos ' a wheel' and dendron ' tree,' in allu- 

 sion to the whorls of leaves. [M. T. M.] 



TROCHOPTERIS elegans is a small but 

 remarkable Brazilian fern, closely resem- 

 bling a rosulate lichen in the habit of 

 growth, the fronds being scarcely an inch 

 long, spreading horizontally, subrotund pi- 

 lose and five-lobed ; the two basal lobes are 

 somewhat contracted, and bear the spo- 

 rangia—which have the many-rayed apical 

 ring characteristic of the Scltizceivece, to 

 which they belong. It is free-veined, 

 allied to Anemia by the fructification being 



, borne on flat rachiform lobes, but distin- 

 guished as well by habit as by the lobes 

 being scarcely contracted, and lying flat 

 in the plane of the fronds, so that they do 

 not resemble panicles. [T. M.] 



i 



; TROCHOSTIGMA. Five species of 



I Japanese plants were formed into a genus 

 under this name by the Dutch botanists 

 Siebold and Zuccarini ; but four of them 

 have since been referred to the older genus 

 Aetinidia, placed by some systematists in 

 the order Dilleniacece, and by others in 

 Ternstromiacece ; while the fifth has been 

 found to belong to the genus Sphcero- 

 stemma, one of the Schizandracece. [A. S.]

 GYPTE. Lawsonia alba.

TROLLIF/S. A genus of herbaceous pe- 

 rennials belonging to the Eanunculacece, 

 distinguished by the following characters : 

 I —Sepals petal-like ; petals very narrow, nu- 

 merous ; stamens and ovaries numerous. 

 ; The genus is represented in Britain by T. 

 europams, the Globe-flower or Globe Ra- 

 nunculus, frequent in mountain-pastures 

 in Scotland, Wales, Ireland, and the North 

 of England. It is a handsome plant, with 

 deeply flve-lobed leaves.which are again cut 

 and serrated ; and large pale-yellow flowers, 

 which before full expansion are nearly glo- 

 bose. This species is often cultivated as a 

 border flower, as are also T. asiaticus and 

 T. caucasicus, plants of similar habit. 

 French: Trolle globaleux ; German: Kvgel- 

 ranunkel. [U. A. J.J

TROPvEOLACE^E. An order established 

 for the genus Tropazolum, which, formerly 

 placed in Geraniacece, has been repeatedly 

 separated therefrom, but isagain reunited, 

 especially on account of the close affinity 

 the structure of its flowers bears to that
