species of tins genus is T. Aslatica, a trailing lierLaceous- 

 stemmed perennial, bearing through great part of the year a 

 profusion of beautiful porcelain-blue flowers, with dark purple 

 blotches. It is propagated by cuttings, which strike readily 

 in a little heat, and when rooted should be potted into a rich 

 open compost of rough peat, loam, and leaf-mould, equal 

 parts, with a little sand added, and shifted on into larger pots 

 as soon as the roots thicken among the soil. In winter it 

 should have a cool position in a stove, and in summer may be 

 placed in the greenhouse, where it should be kept cool, moist, 

 and somewhat shaded. In some sheltered situations it will 

 succeed out of doors in summer, but not generally. 



TORRE YA. [Taxaceae.] Evergreen shrubs. Deep 

 loamy soil. Cuttings or seeds. The chief are T. myristica 

 and T. taxi folia. 



TOUCH-ME-NOT. See Impatiens. 



TOURNEFORTIA. [Ehretiacese.] T. heliotropioides 

 is a Heliotrope-like hardy or nearly hardy plant, not very 

 showy, but a very free bloomer, and useful for small beds. 

 It wdll grow in the open borders, and in all mild w^inters will 

 not be destroyed ; but a plant or two should be kept in a 

 frame through the winter in case of severe weather, which 

 might destroy it. It is increased either by seeds sown in 

 May or by cuttings, and is a low plant, flowering from May 

 to August. 



TRADESCANTIA. Spiderwoet. [Commelinacefe.] The' 

 hardy perennial species of this genus are adapted for the 

 common borders. They are readily increased by division, 

 and only require to be planted in the common soil, and left 

 undisturbed till they get too large, when they must be taken 

 up and divided. The tender species are of less moment, 

 except T. discolor, a curious stove species, and T. iridescens, a 

 pretty dwarf free-blooming crreenhouse herb. 



TREE PEONY. See Moutan. 



TREFOIL See Trifolium. 



TRICHOMANES. Bristle Fern. [Hymenophyllaceae.] 

 Beautiful ferns, inhabiting the tropics for the most part. 

 Very moist rocky, and therefore well-drained soil, with a 

 constant supply of moisture, and a close moist atmo- 

 sphere. The species propagate by division. They just
