(oHrt Chinensis; second, it is a slower grower, and this 

 is an unpardonable fault to the average florist; third, 

 there is a greater demand, generally speaking, for pin- 

 nate-leaved palms than for fan-leaved palms. The un- 

 dersigned has not seen a plant of it for several years, 

 but it was CTilt. in America more than 20 years ago. 



It is dwarf in habit, rather slow-growing, the foliage 

 dark green and somewhat stiff, and in texture decidedly 

 tough. In a young state it bears much resemblance to 

 Jjivisfona australis, though the latter is more spiny and 

 has longer footstalks. •^_ jj_ Taplin. 



TBACHYMfiNE (Greek, rough membrane; alluding 

 to the fruit). Umbelllferte. A genus of 14 species, 12 

 of which aie Australian annual, biennial or perennial 

 herbs, usually hirsute, with ternately divided leaves and 

 blue or white flowers in terminal umbels. Calyx-teeth 

 minute ; petals entire, obtuse, imbricated : fr. com- 

 pressed. Flora Australiensis, Vol. 3.

triparted, with linear, acute, 3-cut lobes : peduncles 

 long, bearing an umbel 2-3 in. across of very numerous

 ternal being longer. July-Oct. Australia. B.M. 2875.

 Charles I.; died about 1638). CommelinAcew. Spidek- 

 WOBT. Thirtv-six species are admitted by C. B. Clarke, 

 the latest monographer, 1881 (DC. :M..)n.i;r. Phaner. 3). 

 This enumeration does not inclmii- 7'. i;, ./in'i- and other 

 recent species. They are all Ann tjraii iMii-miial herbs, 

 ranging from Manitoba to Ary. Ill ina. In lial>it they are 

 various, varying from erect bii^hy siiucius to trailing 

 plants rooting at the nodes. The plants are more or 

 less soft and succulent in texture, although usually not 

 fleshy. The leaves are alternate, sheathing, varying 

 from" ovate to long-linear-lanceolate. The flowers vary 

 from red to blue and white, sometimes solitary but usu- 

 ally in simple cymes or umbels; sepals and petals each 

 3, free, the sepals sometimes colored ; stamens 6, in 

 some species the alternate ones shorter, the filaments 

 iisually more or less bearded at the base or above: 

 ovary 3-loculed, with 2 ovules in each locule, the style 

 single; fr. a 3-loculed dehiscent capsule. The genus 

 Zebrina, usually confounded with this by gardeners, 

 differs, among other things, in having a tubular 

 perianth. 



To horticulturists, Tradescantias are known as hardy 

 herbs, coolhouse plants and warmhouse plants. T. 

 Virginica is the best known of the hardy species, with- 

 standing the climate of the northern states. The Wan- 

 dering Jew of greenhouses and hanging baskets, usu- 

 T. tricolor, is partly T. fluminensis and 

 partly Zebrina pendula. T. liegince 

 is perhaps the best known warmhouse 

 species at present, although various 

 species may be expected in botanic 

 gardens and the collections of ama- 

 teurs. The glasshouse species are 

 essentially foliage plants. Several 

 have handsomely striped leaves. All Trades- 

 cantias are free growers, propagating with ease from 

 cuttings of the growing shoots.

 Central Brazil to Argentina. — One of the commonest of 

 greenhouse aud basket plants. In greenhouses, usually 

 grown under the benches. When the plants grow very 

 vigorously and have little light, ^ 



they are usually green, and this tI* '.i,;' 



is the form commonly known as ^-^ ' ' 



Viridis. There are forms with Ivs. 

 striped yellow and white, but these 

 colors usually do not hold unless 

 there is abundance of sunlight. 

 In light places, the Ivs. become red- 

 purple beneath. Very easily propa- 

 gated by cuttings or pieces of 

 shoots at any time of the year. 

 The plant needs plenty of moisture 

 in order to grow vigorously. Three 2540.
