GUAVA 



GUZMANIA 



be potted off when very small, and kept growing in pots 

 until wanted for permanent setting in the orchard, as 

 the plants in open ground do not transplant well. Rooted 

 cuttings, of course, should be treated the same as seed- 

 ling plants as to final handling. 



Guavas grow well on any soil, sandy or clayey, rich 

 or poor, dry or moist; but they will not live in a bog. 

 On too rich soil the growth is apt to be rank and the 

 quality of the fruit injured. This fruit tree is as easily 

 grown under sheds as is the pine-apple in Florida, and 

 when thus protected is certain to bear abundantly, even 

 well out of the tropics. E. N. REASONER. 



GUAZUMA (name of Mexican origin). Sterculidcece. 

 Seven or eight tropical American (one also Javan) 

 trees, with small white, pink or yellow fls. in short- 

 peduncled, axillary cymes. Petals 5, often 2-parted: 

 stamens 10, united into a tube or column, some of them 

 sterile; styles 5: fr. a 5-loculed nut the size of a filbert: 

 Ivs. 2-ranked, serrate. Allied to Theobronca, but that 

 genus has a berry-like fr., entire Ivs., fascicled or soli- 

 tary fls., and a different staminal column. G. ulmifolia, 

 Lam., the "Guacima" of Mexico, is offered by Fran- 

 ceschi. It becomes a large tree: branchlets powdery: 

 Ivs. ovate to oblong-lanceolate, somewhat pointed, ob- 

 lique at base, powdery beneath when young but becom- 

 ing glabrous: nut nearly globular, with 5 furrows. The 

 tree is said to yield medicinal preparations.

GUINEA HEN FLOWER. Fritillaria Meleagris. 



GUIZOTIA (after Guizot, the celebrated historian). 

 Compdsitce. This genus has 5 species of annual herbs 

 from tropical Africa, one of which has some economic 

 interest from its oil-producing seeds. Neither this nor 

 closely allied genera have much ornamental value. The 

 plants have yellow heads, about 2 in. across, with 8 

 broad, 3-toothed rays and a leafy outer involucre. Seeds 

 can be obtained by the pound from S. Fla., and they are 

 listed among miscellaneous agricultural seeds in a few 

 of the largest European catalogues. The plant is cult, 

 in India for the oil. 



Abyssinica, Cass. (G. oletfera, DC. Verbesina saliva, 

 Roxb.). Lvs. opposite, lanceolate, clasping, remotely 

 serrate. B.M. 1017.

GUNNERA ( J. Ernst Gunner, 1718-1773, was a Swed- 

 ish bishop and botanist, and wrote a local flora). Halo- 

 ragdcece. The little family Haloragaceae comprises 

 about 100 widely scattered and heterogeneous species in 

 9 genera. In the northeastern states are the aquatic 

 genera Callitriche, Proserpinaca, Hippuris, Myriophyl- 

 lum. These comprise small and mostly inconspicuous 

 plants. In the Australian region are the endemic gen- 

 era Loudonia and Meionectes ; and there remain Ser- 

 picula, Gunnera, and Haloragis, with very wide and dis- 

 jointed distributions. Gunnera has perhaps a dozen 

 known species in S. Afr., Abyssinia, Java, Tasmania, 

 Hawaii and S. Amer. In general appearance the Gun- 

 neras are wholly unlike our native haloragaceous plants. 

 The Ivs. are gigantic and more or less orbicular, radi- 

 cal : fls. perfect or imperfect, small, packed in a great 

 cob-like spike ; petals 2 or none ; calyx none, or with 

 2-3 lobes ; stamens 1 or 2 : ovary 1-loculed, bearing 2 

 filiform styles : fr. a drupe. They are perennial herbs, 

 and with protection the two following species may be 

 grown even in some of our northern states. 



Gunneras are perhaps the noblest of all lawn foliage 

 plants. To produce satisfactory effects, rich, moist 

 ground is indispensable. The plants must never suffer 

 for want of water. Full exposure to sun is advisable, 

 but they should be sheltered from severe winds, else 

 the leaves will be damaged. Ample winter protection

s 



should be provided for. A liberal covering of leaves o I 

 litter, held in place by brush or branches, will generall 

 keep them from harm. Apply the covering in Decembe I 

 and remove early in spring. Prop, by division. Seed j 

 are also employed, and they can now be readily st i 

 cured. 



manicata, Lind. Stem thick and very short, th 

 titanic crown of Ivs. rising from the ground : petiole j 

 often as tall as a man, prickly : blades becoming 5 t 

 10 ft. across, orbicular in general outline, variousl I 

 lobed, crenate, furrowed and channeled along the grea 

 veins: fls. green: spikes dense and tapering, often mor ; 

 than 1 ft. in diam. and 3-4 ft. tall. S. Brazil. I.H 

 31 :531. Gn. 45, p. 21 ; 50, p. 455 ; 54, p. 385. G.C. Ill 

 14:589. G.F. 8:55. The crown of Ivs. sometimes nieas I 

 ures from 25-35 ft. across. This is the better species. 



Chilensis, Lam. (G. scabra, Ruiz & Pav.). Not so ro 

 bust, the Ivs. smaller and less spiny, and the fl. -spike 

 less tall: fls. reddish. R.H. 1862, p. 310; 1894, p. 397 

 Gn. 49, p. 151. G.C. II. 26:425; III. 8:665. -Longe 

 known in cult. Thrives in drier soil.

GUTIERREZIA (personal name). Compdsitce. Abou 

 18 species of herbs or subshrubs, often resinous, al 

 American, mostly western N. American. They are m 

 branched from the base, and have narrow, entire 

 and clusters of small yellow heads. 



Euthamise, Torr. & Gray. More or less woody at base 

 seldom over 1 ft. high : involucre turbinate, 2 lines long 

 rays and disk-fls. each 3-9 : akenes silky-pubescent 

 pappus of about 9 chaffy scales. N. W. N. Amer. 



GUZMANIA (A. Guzmann, Spanish naturalist). Bro 

 meliacece. Includes Caraguata. About 70 tropica 

 American Bromeliads, of which several are fairly wel i 

 known ornamental glasshouse subjects. They closeh 

 resemble the erect-growing Tillandsias, but differ ir 

 technical characters: fls. in a simple spike-like termina 

 cluster, tubular, the outer segments or calyx oblong an< 

 obtuse, the inner or petals shorterthan the tube; anther^ 

 inserted on the throat of the tube, and united by theii 

 edges around the style. Grown in the warmhouse, alonf. 

 with Billbergia and Tillandsia, which see for culture 

 Closely allied to JSchmea. Many species are cult, ii 

 fanciers' collections in the Old World. For G. picta, set 

 Nidularium. For G. Legrelliana, see ffohenbergia. G. 

 rosea, a name which has appeared in the Amer. trade, if 

 probably an JSchmea. Monogr. by Mez, DC. Monogr. 

 Phaner. 9 (1896). 



A. Corolla (or segments) purple or red. 



lingulata, Mez (Caraguata lingulata, Lindl. C. 

 spUndens, Bouche". C. lingulata spUndens, Hort.). 

 Epiphyte : Ivs. many, lanceolate or ensiform, l/^ ft. 

 long, remotely toothed : spike becoming drooping, 

 showily red-bracted: expanded fl. about as long as the 

 long-pointed bracts, the tube yellowish and the limb 

 blue-purple. W. Indies, Cent. Amer., and adjacent S. 

 Amer. B.R. 13:1068. F.S. 11:1091. -Handsome. Var. 

 cardinalis, Andre" (Caraguata cardinalis, Andre). Bright 

 scarlet: very showy. Columbia. I.H. 27:374. R.H. 

 1883:12. 



AA. Corolla (or segments) white. 



tricolor, Ruiz & Pav. (G. fragrans, Hort., at least m 

 part. G. grdndis, Hort., in part. G. maculdta, Hort., in 

 part. G. monostdchya, Rusby). Lvs. several to many, 

 broad and more or less recurved, entire on the edges, 

 usually shorter than the stout, erect spike: lower bracts 

 green streaked with black, upper ones red-tinged: co- 

 rolla white. W. Indies, Cent. Amer., S. Amer. L.B.C- 

 5:462. F.S. 9:918. B.M. 5220. -Interesting because of 

 its combination of green, red and white. Some, at least. 

 of the horticultural plants which pass as G. fragrans 

 belong to jEchmea, eburnea, Baker (Canistrum Lin- 

 deni, Mez. Nidularium Lindeni, Regel). This si
