GLADIOLUS 



GLEDITSIA 



the 2 side segms. widely flaring and sometimes meas- 

 uring 6-8 in. from tip to tip; upper segm. long and 

 upright. First exhibited by Lemoine, the raiser, in 

 1889. The finest race, characteristically is full-open and 

 large fls., in brilliant shades of red and purple. Gn. 

 41:190. G.C. III. 13:131. Gn. W. 7:797. 



32. Childsii (G. gandavensis x G. Saundersii). Fls. 

 wide open and large, with very broad petals: st. large 

 and soft, taking up water well when fls. are cut. Origi- 

 nated by Max Leichtlin, Germany. 



33. Froebelii, Hort., is G. purpiireo-auratus x G. 

 gandavensis; G. Engesseri, Hort., is of similar paren- 

 tage; also G. Brineri, Hort. 



34. turicensis, Hort. (Fig. 1650), is the offspring of 

 a large-fld. G. gandavensis and G. Saundersii var. 

 superbus. It is a fine purplish crimson, the lower segms. 

 being beautifully marked with white: fls. 3 in. across. 

 G.F. 3:89 (reduced in Fig. 1650). This and the last 

 3 are the work of Froebel & Co., Zurich. 



35. princeps, Hort. (G. hybridus princeps). Produced 

 by W. W. Van Fleet, from seed of G. cruentus x G. 

 Childsii; like the seed-parent in its scarlet-crimson 

 coloring, with white and cream feather markings on the 

 lower segms. : very large, the flat circular bloom expand- 

 ing to 6 in. diam. : plant very large. G. 24 : 663 ; 34 : 533. 

 Gn. 60, p. 197. G.M. 44:629. 



36. prsecox, Hort. Very early-flowering types, 

 results of crossing of horticultural groups (p. 1340) . 



37. Kunderdii, Hort. A strain or group of the ruf- 

 fled or fluted kinds. See p. 1340. 



Many species of Gladiolus are likely to be discussed in horticul- 

 tural literature. The following have recently been prominently 

 mentioned: G. carmineus, C. H. Wright. Resembles R. ramosus, 

 Paxt., but differs in its laxer habit, longer spathe and yellow anthers: 

 slender, 1J^ ft.: Ivs. linear, acuminate, 8 in. long and Jjjin. broad: 

 fls. carmine, about 3 in. across; tube narrow-funnel-shaped, white 

 outside; segms. ovate, acuminate, 2 of the inner bearing a dark 

 spot with a pale center; stamens rather more than half length of 

 perianth. 8. Afr. B.M. 8068. G. glaiicus, Heldr. Dwarf, not 

 exceeding 12 in.: st. and Ivs. erect and stiff: fls. many, bluish red 

 with red and white stripes at base. Greece. G. MacTdnderi, Hook, 

 f. St. slender, 2 ft.: Ivs. narrowly linear, the lower about 1 ft. long: 

 fls. 5-6, the tube yellow, broad segms. scarlet and 1 l /i in. across. 

 E. Trop. Afr. B.M. 7860. Named for Professor Mackinder, 

 Oxford, who collected seeds at 10,000 ft. on Mt. Kenia in 1900. 

 One of the Homoglossum section. L H R 



1651. Glaucium flavum. 



GLASSHOUSE. Any glass structure in which plants 

 are grown, particularly one that is large enough to 

 admit the operator. It is a generic term. See Green- 

 house. 



GLAUCIUM (name refers to glaucous foliage). 

 Papaveracese. HORNED POPPY. Annual, biennial or 

 occasionally perennial herbs, a few of which are grown 

 for their large poppy-like flowers and glaucous-blue 

 foliage. 



Sepals 2; petals 4; stamens many; ovary with 2 

 (rarely 3) cells, the stigmas miter-shaped, the fr. becom- 



ing a long silique-like caps.: Ivs. alternate, lobed or 

 dissected. A dozen or more species of S. Eu. and W. 

 Asia. 



Glauciums are low, branchy herbs, often some- 

 what succulent, with large flowers, mostly yellow or 

 orange, but varying to red and purple. The flowers are 

 usually short-lived, but they are borne in rapid suc- 

 cession. They are well adapted for foliage effects in 

 borders or edgings. Of easy culture in any good soil. 

 They prefer an open, sunny situation. Mostly propa- 

 gated by seed, but the perennial kinds by division; 

 however, the perennials are short-lived, and usually 

 had best be treated as biennials; they should be grown 

 from seed. Hybrids are announced by Burbank. 



flavum, Crantz (G. luteum. Scop.). HORN POPPY, 

 or SEA POPPY. Fig. 1651. Sts. stout, 1-2 ft., pubes- 

 cent: radical Ivs. 2-pinnate and hairy, the upper clasp- 

 ing and sinuate-pinnatifid and cordate at the base: fls. 

 generally solitary, on long sts. 2-3 in. across, vellow 

 or orange. Eu. C.L.A. 1:139. Gn. M. 9:86. Spa- 

 ringly naturalized E. Perennial or biennial; sometimes 

 grown as an annual. Var. tricolor, Hort. (G. tricolor, 

 Vilm.) has been advertised. It has parti-colored fls. 

 and is showy. G.C. III. 36:115. G.M. 48:697. Gn. 

 66, p. 59. 



corniculatum, Curt. (G. phceniceum, Gaert. G. 

 rubrum, Hort.). Lower: radical Ivs. pinnatifid, pubes- 

 cent, the upper ones sessile and truncate at the base: 

 fls. red or purplish, with a black spot at the base of each 

 petal. Eu. Mostly annual. G. Fischeri, Hort., is 

 probably a form of this. 



leiocarpum, Boiss. A velvety perennial with oblong, 

 sinuate-dentate, or much-divided Ivs. which in the upper 

 part of the plant are sinuate-lobed : fls. yellow, the calyx 

 somewhat papillose. Medit. region. Scarcely a showy 

 member of the genus. L jj jj 



N. TAYLOR. t 



GLAUX (Greek, sea-green). Primulacese. One small 

 little pale herb, seldom seen in gardens, G. maritima, 

 Linn. St. 9 in. or less high, erect or spreading, peren- 

 nial by slender creeping rootstocks, growing in salt 

 marshes and seacoasts from New Jersey and Calif, 

 northward, and also in Eu. and Asia: Ivs. oval to. oblong- 

 linear, entire and sessile, Hi n - or less long: fls. purplish 

 or white, the corolla wanting; calyx with 5 petal-like 

 lobes; stamens and style exhibiting dimorphism: fr. a 

 5-valved few-seeded caps. L_ jj_ jj. 



GLAZldVA: Cocos insignia. 

 GLECH6MA: Nepeta. 



GLEDITSIA (after Gottlieb Gleditsch, director of 

 the botanic garden at Berlin; died 1780). Syn. Gle- 

 ditschia. Leguminbsae. HONEY LOCUST. Ornamental 

 trees grown chiefly for their handsome finely divided 

 foliage; also the large conspicuous pods and the branched 

 spines are attractive. 



Deciduous, usually with large branched spines on 

 trunk and branches: Ivs. without stipules, alternate, 

 abruptly pinnate, often partly bipinnate on the same 

 If. or wholly bipinnate, both usually on the same tree: 

 fls. polygamous in racemes or rarely panicles; calyx- 

 lobes and petals 3-5, petals nearly equal, not much 

 longer than calyx, stamens 6-10; style short, with 

 large terminal stigma: pod compressed, mostly large 

 and indehiscent, 1- to many-seeded. About 12 species 

 in N. Amer., E. and Cent. Asia, in Trop. Afr. and in 

 S. Amer. 



The honey locusts are large trees with spreading 

 branches forming a broad graceful rather loose head, 

 with finely pinnate foliage, generally light green and 

 turning clear yellow in fall; the greenish flowers appear- 

 ing in racemes early in summer are inconspicuous, but 

 the large, flat pods are ornamental and the fertile tree 

 is therefore to be preferred for planting. G. triacanthos
