Trichodesma 



( 404 ) 



Trichopus 



TRICHODESMA. 



Coarse growing, hardy, half-hardy, or greenhouse 

 herbs (ord. Boraginere), with flowers in racemes, 

 and entire leaves. Propagation, by division or 

 seeds. Common soil. 



Principal Species : 

 physaloides, 1' to '2', grh. zeylanicum, 4', Aug.,hdy. 



per., wh., pur. ami., pale bl. (syn. 



Borago zeylanica). 



TRICHOGLOTTIS. 



Stove Orchids (ord. Orchidacese) with small 

 flowers. They do well in. pans of sphagnum with 

 the temperature of the East India house. 



Principal Species : 

 cochlearis, 8", wh., sepals blotched br. (>J>i. Clei- 



and petals barred pur. , sostoma dawsoniaua) . 



lip with pur. blotches. fasciata, sepals banded 

 dawsoniaua, sulphur yel. pale br., lip wh., yel., 



outside, darker inside, pur. (correctly Staur- 



barred br., lip or. yel., opsis fasciata). 



TRICHOMANES (BRISTLE FEBN). 



Stove or greenhouse Ferns (ord. Filices). Many 

 of the species are exceedingly beautiful, some of 

 the dwarf ones ranking among the daintiest of 

 Ferns. The general aspect of the genus is very 

 varied. Some plants make quite large fronds 1' to 

 1 j' long, and correspondingly wide, whilst the fronds 

 of others are scarcely 1" in length. In shape also 

 a great variation is found, some being simple, 

 others pinnate, and others again divided into 

 innumerable segments. In some cases short stems 

 are made, which bear large heads of fronds, whilst 

 in others the stems are creeping and very small, 

 the leaves being borne singly. As a whole the 

 leaves are very thin, and covered with star shaped 

 or forked hairs, from which tiny drops of moisture 

 are suspended. The popular Killarney Fern, T. 

 radicans, is found wild in Ireland. In'almost all 

 cases they are found in warm, moist situations in 

 dense shade on the lower portions of trunks of 

 trees, damp rocks, etc. Under cultivation they 

 must always have a moist atmosphere, abundance 

 of water when growing, and perfect drainage. 

 The most suitable compost is fibrous peat, inter- 

 mixed with soft sandstone. The compost should 

 be mounded up over the top of the pot or pan, so 

 that plenty of space may be free for drainage. 

 The dwarf rhizomatous species may be planted on 

 pieces of soft Tree Fern stem or sandstone, which 

 is, indeed, the best method to adopt. As Wardian 

 case subjects Trichomanes are charming, whilst a 

 few species can be cultivated in a close, cold frame. 



The following genera are now merged in Tricho- 

 manes. Feea, Hymenostachys, Involucraria, Lacos- 

 tea, Lecanium, Microgonium, and Phlebiophyllum.

TRICHOPETALUM. 



The only species (ord. Liliacere) is a half-hardy 

 herb with a fleshy rootstock and fibres. Propaga- 

 tion is by division, and a light, rich soil is needed. 

 The plants do well in pots, or they may be planted 

 out in a frame, provided the bed is well drained, 

 They will not succeed otherwise. 



Only Species : 



stellatum, 1' to 3', My., Je., hlf-hdy., grn. (syns. 

 gracile and Anthericum plumosum ; correctly 

 Bottionea thysanthoides). - 



TRICHOPILIA. 



Description. Showy, epiphytal Orchids (ord. 

 Orchidaceic), which make dense masses of small 

 pseudo-bulbs, each of which is terminated by a 

 single leaf. From the bases of the pseudo-bulbs 

 the flower spikes appear, assuming a pendulous 

 habit as they approach maturity. The genus has 

 been separately described under Leucochyle and 

 Pilumna. 



Propagation. By division when growth com- 

 mences in spring. 



Soil. The most suitable compost is made up of 

 fibrous peat, living sphagnum, charcoal, and broken 

 crocks. Orchid baskets should be used, the com- 

 post being formed into a mound above the top of 

 the basket. 



Other Cultural Points. An intermediate or 

 warm greenhouse temperature is necessary, and on 

 no account should more heat be given. During 

 the growing season a fair amount of water is neces- 

 sary-, reducing the supply when growth is finished.
