SPATHOGLOTTIS 



SPERGULA 



3203 



3656. Spathoglottis 

 Vieillardii. (XH) 



labellum not spurred, lateral lobes somewhat convo- 

 lute, middle lobe clawed; column slender; pollinia 8. 

 About 40 species in Asia, Austral., and the Malay Isls. 

 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 sphag- 

 num moss with 

 a little chopped 

 sod added ; about 

 half of the pot 

 should be de- 

 voted to drain- 

 age. They all 

 require a liberal 

 amount of water 

 when growing, 

 but only enough 

 to keep them in 

 sound condition 

 when at rest. 

 They are rather 

 hard to increase 

 by division and 

 the supply de- 

 pends upon new 

 importations.

S. aitreo-Vieitt&rdii, Hort., is a hybrid between this and S. aurea. 

 Fls. pale chrome-yellow, with the sepals slightly and the petals 

 profusely dotted with crimson, the tips of the lobes of the lip rich 

 crimson. G.C. III. 23:309. G.M. 41:308. S. C<Wrnanit=S. aurea

 fls. numerous, rose-purple or pale lilac, about 1 in. diam. ; sepals 

 lanceolate: petals linear-lanceolate; lip linear, auricled at base, with 

 2 yellow brown-spotted tubercles. X. Burma. B.M. 7964. S. 

 ketrenfis=S. plicata var. Micholitzii X S. Vieillardii. -S. Kim- 

 baOiana, Hook., is often regarded as a variety of S. aurea, from which 

 it differs in having the backs of the sepals mottled with red-brown, 

 the crest glabrous, and narrower Ivs. B.M. 7443. S. plicata var. 

 Alicholitzii is advertised by Sander. Fls. amethyst -color, with the 

 segms. broader than in tho tvpe. Habit more dwarf. S. Southeri- 

 ana, F. M. Bailey. Fls. in upright spikes, more than 1 in. across;

SPECULARIA (from Speculum Veneris, meaning 

 Venus' looking-glass). Campanulacex. VENUS' LOOK- 

 ING-GLASS. Erect or decumbent, hispid or glabrous 

 annual herbs, suitable for outdoor garden planting. 



Leaves alternate, entire or dentate: fls. blue, violet, or 

 white, sessile or short-pedicelled, axillary; calyx-tube 

 adnate, oblong or linear, limb 5-parted; corolla sub- 

 rotate, or broad-campanula te, 5-lobed; stamens free; 

 ovary inferior, 3-celled: caps, oblong or linear. About 

 10 species, northern hemisphere, 1 also occurs in S. 

 Austral. Closely allied to Campanula but differing by 

 the very long calyx-tube, ovary, and caps. The long 

 calyx-tube is one of the most conspicuous features of 

 the plant and has perhaps served to suggest the handle 

 of the mirror. There is one North American species, S. 

 perfoliata, which differs from all the rest in having per- 

 foliate Ivs. and the caps, dehiscing laterally near the 

 middle instead of near the calyx-lobes. It is a weed. 



S. Speculum is a pretty little hardy annual herb 

 with five-lobed blue flowers not quite an inch across. 

 The plants grow about 9 inches high, bloom in spring 

 and summer and are desirable for edging flower-beds. 

 They are of easy culture. See Annuals.

Speculum, DC. (Campanula Speculum, Linn.). VE- 

 NUS' LOOKING-GLASS. Fig. 3657. Erect, 9 in. high: 

 calyx glabrous or pubescent, the tube constricted at the 

 apex; lobes finally reflexed, according to DeCandolle. 

 Eu. B.M. 102. Var. alba, Hort., is a white-fld. form. 

 Gn. 72, p. 253. Var. procumbens, Hort., is offered 

 abroad in addition to lilac and double forms. R.H.

pentagonia, DC. Calyx pilose, lobes spreading. Asia 

 Minor. B.R. 56. This species is not now advertised 

 in Amer. Some specimens have narrow Ivs. and longer 

 calyx-tube than S. Speculum. An interesting feature of 

 this species (and perhaps others) is the 5-angled fl.- 

 buds. F. TRACY HuBBARD.f

SPERGULA (Latin, 

 spargere, to scatter; the 

 seeds are said to be ex- 

 pelled ) . Caryophyllacese. 

 Annual herbs including 

 SPURRY (which see), a for- 

 age plant adapted to poor 

 dry sandy soils: Ivs. subu- 

 late, appearing whorled 

 from the cluster of second- 

 ary Ivs. at the axil; stip- 

 ules small and scarious: 

 fls. pedicelled, in cymose 

 racemes; sepals 5 ; petals 5, 

 entire; stamens 10, rarely 

 5; styles 5, alternate with 

 the sepals; ovary 1-celled, 

 many -seeded: caps. 5- 

 valved, the valves oppo- 

 site the sepals. About 5, 

 possibly more species, tem- 

 perate regions of the world. 

 Some of the species are 

 dichotomously branched, 

 but the following has clus- 

 ters of branches originating 

 at or near the base.
