SPARTIUM 



fiber, which is used in S. France and Spain for making 

 ropes, cords and cloths. Many species of Cytisus and 

 Genista were formerly referred to this genus. For 

 Spartium jEtnense, Biv., ;S. ferox, Poir., S. monosper- 

 mttm, Linn., S. radiatum, Linn, and S. virgafum, Ait., 

 see Genista; for S. purgans, Linn., and S. scoparium, 

 Linn., see Cytisus; Spartium multiflorum, Ait.=Cyti- 

 sus albus.

SPATHIPHtLLUM (Greek word, referring to the 

 leaf-like spathes). ArAcea;. About 20 species of nearly 

 stemless plants, mostly from tropical America, with 

 large, oblong or lanceolate, acuminate or cuspidate, 

 long-petioled leaves and flowers on a long-peduncled 

 spadix subtended by an oblong or lanceolate, leaf-like, 

 white, persistent, flat spathe: stigma 3^-lobed: ovules 

 in each locule 2-8, fixed at the interior angles of the cells. 

 Gardeners recommend as soil for their culture a mixture 

 of leaf-mold, peat and fibrous loam, together with some 

 sand and charcoal.

 minate, 8-9 in. long: spathe white on both sides, lan- 

 ceolate, acuminate, 4-5 in. long; spadix 2 in. long. I.H. 

 29:450. G.C. II. 19:500. F.W.Barclay. 



SPATH0GL6TTIS (Greek, spathe and tongue; said 

 to refer to the shape of the lip). OreJtiddcem. Plants 

 agreeing with Bletia in habit and form of inflorescence: 

 pseudobulbs broadly conic, 1-3-lvd. : Ivs. elongate, long- 

 petioled, narrow, plicate, articulated : scape lateral, 

 bearing large fls. in a terminal raceme: sepals free, 

 subequal; petals similar or broader and longer; label- 

 lum not spurred, lateral lobes somewhat convolute, mid- 

 dle lobe clawed; column slender: pollinia 8. About 10 

 species in Asia, Australia and the Malay Islands. 



Spathoglottises grow best at the warm end of the Cat- 

 tleya or Brazilian house in a moist, shady location. Pot 

 culture suits them best, and the compost should consist 

 principally of equal parts peat fiber and sphagnum 

 moss with a little chopped sod added; about one-half of 

 the pot should be devoted to drainage. They all require 

 a liberal amount of water when growing, but only 

 enough to keep them in sound con.dition when at rest. 

 They are rather hard to increase by division and the 

 supply depends upon new importations. 



pUcata, Blume. Lvs. 2-4 ft. long, finely acuminate, 

 scape 2-3 ft. high, with a raceme 6-12 in. long: fls. 1 in. 

 across, lilac; sepals and petals broad, acute; middle 

 lobe of the labellum long and narrow, cuneately dilated 

 at the tip; calli yellow, villous. Malay Peninsula. 



aiirea, Lindl. (S.plic&ta, Griff.). Lvs. 12-18 in. high, 

 narrowly lanceolate: scape tall and stout, 2 ft. high: 

 raceme 6-8 in. long: fls. IH in. across, golden yellow; 

 sepals broad, obtuse ; middle lobe of the Jabellum 

 equaling the falcate lateral lobes, narrowly lanceolate. 

 Malay Peninsula. G.C. III. 4:93.-The lip varies, being 

 sometimes broad and retuse at the apex.
