SPATHODEA.

Stove terrestrial Orchids (ord. Orchidaceos), with 

 conn-like pseudo-bulbs and Grass-like foliage. 

 Propagation, by division. Soil, leaf mould or 

 fibrous loam, with a little sand or peat and chopped 

 sphagnum. Free drainage, and liberal supplies of 

 water in the growing season.

SPAWN. 



The vegetative portion (mycelium) of Mush- 

 rooms. These white threads (hyphse) are to be 

 seen growing on decaying animal matter, horse drop- 

 pings, etc. (For the artificial production of spawn, 

 see MUSHROOMS.) If kept nearly or quite dry this 

 mycelium has remarkable vitality, and will 'often 

 grow after lying dormant for several years. The 

 bulbils developed from old corms of Gladioli are 

 spoken of as " spawn." As these are too small to 

 plant separately, they are " sown " in pans or drills 

 of prepared soil in the same way as seed. 



SPECULARIA. (VENUS' LOOKING- 

 GLASS.) 



Pretty, small-flowered, generally hardy, annual 

 herbs (ord. CampanulaceEe), best known in gardens 

 by the neat little annual Speculum (syn Campanula 

 Speculum), sometimes used in the borders or in 

 beds. Propagation, by seeds. Common soil. 



Principal Species : 

 biflora, 1', ,Te., hdy. ann., perfoliata, 4" to 18", Je., 



bl. (syn. californica). hdy. aim., purplish bl. 



falcata, 6", Jy., hdy. Speculum, 1', Jy., hdy. 



ann., ro. ; castellana is ann., pur (syns. ar- 



a yar. vensis, cordata, hirsuta, 



hybrida, 6" to 12", Jy., hirta, and Campanula 



hdy. ami., bl. and lil. Speculum). There 



(/. Campanula hy- are varieties in various 



brida). colours from wh. to bl., 



pentagom'a, 1', Jy., hdy. in single and double 



ann., bl. (*y>i. Cam- forms. 



panula peutagonia. ) 



SPEIRANTHA. 



A half-hardy or greenhouse herb (ord Liliacere) 

 with rosettes of leaves and a spike of from twenty 

 to thirty flowers like those of an Albuca, to which 

 it is allied. Propagation, by seeds or division. 

 Soil, sandy loam. 



Only Species : 



convallarioides, 6", Je., wh. or grn. (syn. Albuca 

 Gardeni). 



SPERGULA. 



Hardy annual herbs (ord. Caryophylleas), some- 

 times used as an edging instead of Grass. The 

 plant generally grown as Spergula pilifera, and 

 useful for the above purpose or for carpeting taller 

 plants, is properly Sagina subulata (see SAGINA), 

 sometimes named Sagina pilifera or S. glabra. The 

 yellow-leaved form of this is desirable. The 

 Spergulas are generally white flowered, but as a 

 rule so worthless in the garden as not to require 

 naming here. 



SPERMACOCE. (BUTTON WEED.) 

 Stove, greenhouse, or hardy annual or perennial 

 herbs or sub-shrubs (ord. Rubiacese). None is of 

 any value to the gardener. Strigosa of Botanical 

 Magazine 1558 is Crusea rubra. 



Speedwell (see Veronica). 

 Spennera (see Aciotis). 

 Spergulastrum (see Stellaria).
