i6o PLANT CULTURE 



Culture. A warm house suits it best, but it may be used as a 

 window plant. With proper care it may be made to flower most 

 of the year. 



Propagation. By seeds. 



TINNEA. T. (Bihiopica is a shrubby greenhouse plant some- 

 times called the Tree Violet, owing to its flowers having the same 

 fragrance as the Violet. 



Culture. It is adapted to the warm house. 



Propagation. It is propagated from good-sized cuttings of 

 the dormant wood. 



TOCOCA (Sphaerogyne). T. platyphylla bears the distinction 

 of being one of the finest foliage plants in cultivation. Together with 

 Cyanophyllum magnificum, another noble-leaved plant, it belongs to 

 the same order as our common Meadow Beauty (Rhexia). 



Culture. They require a shady and fairly moist place in a warm 

 house. In potting, use leafmold and fibrous loam, and give good 

 drainage. 



Propagation. Both of these plants look as if they would be 

 very difficult to propagate, but, on the contrary, they are exceed- 

 ingly easy subjects, so easy that if the conditions are all right, there 

 is no excuse for losing a cutting. Mossing the tops is a rather slow 

 and unsatisfactory method, and, I think, single-eye cuttings can be 

 just as rapidly grown into specimens as successfully rooted tops. 

 During January the plants are in less active growth than at any 

 other period, consequently this is the best season for putting in the 

 cuttings. Split the stems, making single-eye cuttings; shorten back 

 the leaves to within about 2 inches of the leafs talk, leave about 23^ 

 inches of stem (less than this will root poorly) ; put firmly in sand of 

 warm propagating bed, taking care that the under part of the piece 

 of leaf lies flat on the sand; cover with glass. Rooting will be in- 

 dicated by the buds elongating. Pot in thumb pots and keep close 

 for a time. 



TRICHOSPORUM (.Bschynanthus) . Along with a dozen 

 other beautiful species, T. grandiflorum can be grown successfully 

 with the warm-house Orchids. All the species are worth growing 

 and as they flower much more freely than the Orchids, they help 

 to brighten up the sometimes flowerless plants with which they 

 associate. 



Culture. They should not be allowed to flower the first year, 

 thereby increasing the future flowering ability of the plant. Pinch
