GUAVA 



GUZiMANIA 



be potted off when very sraaH, and kept growing in pot;^ 

 until wanted for pprmanent setting in the orchard, as 

 the plants in open ground do not transplant well. Rooted 

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

 ling plants as to tiiial 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 al>undantly, even 

 well out of the tropics. e. N. Reasoner. 



GTJAZtJMA fnamo of Mexican origin). StercuUdcece. 

 Seven or eight tropical American (one also Javan) 

 trees, with small wliite, 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; styles5: fr. a Sdocnled nut the size of a lilbert: 

 Ivs. 2-ranked, serrate. Allied to Tlieobroma. 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. Itbecomes 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 ELOWER. FritiUaria Meleagris. 



GUIZOTIA (after Guizot, the celebrated historian). 

 Ooinp6.si((i^. 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 aleafy 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.

 serrate. B.M. 1017.

GUNN:£RA (J. Ernst Gunner, 1718-1773, was a Swcd- 

 i^^h Itisliop and botanist, and wrote a local flora). Halo- 

 raffCtccd.'. The little family Haloragacese comprises 

 about 100 widely scattered and heterogeneous species in 

 genera. In the northeastern states are the aquatic 

 genera Callitriehe, Proserpinaca, Hippuris, Myriophyl- 

 lum. These com])risu small and mostly inconspicuous 

 plants. In tlie Australian region are the endemic gen- 

 era Loudonia and Meionectes ; and there remain Ser- 

 picula, tiunnera, 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- 

 noras are wholly imliko our native haloragaceous plants. 

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

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

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

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

 filiform styles : f r. a drupe. They arc perennial herbs, 

 and with protection the two folh»wiiig 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 exposui-e to sun is advisable, 

 but they should be sheltered from severe winds, else 

 the leaves will be damaged. Ample winter protection 



should be provided fnr. A liberal covering of leaves or 

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

 keep them from harm. Apply the covering in December 

 and remove early in spring. Prop, by division. Seeds 

 are also employed, and they can now be readily se- 

 cured. 



manic^ta, Lind. Stem thick and very short, the 

 titanic crown of lvs. rising from the ground : petioles 

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

 10 ft. across, orbicular in general outline, variously 

 lobed, crenate, furrowed and channeled along the great 

 veins : fls. green : spikes dense and tapering, often more 

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

 31:531. Gn.45,p.21; 50, p. 45.5 ; 54, p. .385. G.C. III. 

 14:589. G.F. 8:55. — The crown of lvs. sometimes meas- 

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



ChiUnsis, Lara. (G. scdbra, Ruiz & Pav,). Not so ro- 

 bust, the lvs. smaller and less spiny, and the fl. -spikes 

 less tall: fls. reddish. R.H. 1802, p. 310 ; 1894, p. 397. 

 Gn. 49, p. 151. G.C. II. 20:425; 111. 8:005, -Longer 

 known in cult. Thrives in drier soil.

GUTIERRfiZIA (personal name). CompdsilcB. About 

 18 species of herbs or subshrubs, often resinous, all 

 American, mostly western N. American. They are much 

 branched from the base, and have narrow, entire lvs. 

 and clusters of small yellow heads. 



Euth^mi£e, Torr. & Gray. More or less woody at base, 

 seldom over 1ft. 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- 

 meUdcece. Includes Caragiiaia. About 70 tropical 

 American Bromeliads, of which several are fairly well 

 known ornamental glasshouse sul>jects. They closely 

 resemble the erect-growing Tillandsias, but differ in 

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

 cluster, tubular, the outer segments or calyx oblong and 

 obtuse, the inner orpetals shorterthan the tube; anthers 

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

 edges around the style. Grown in the warmhouse, along 

 with Billbergia and Tillandsia, which see for culture. 

 Closely allied to ^Echmea. Many species are cult, in 

 fanciers' collections in the Old World. For G. plcta,se& 

 Niduhtrium. For G. Ijef/reUiana, nee Uohenbergia. G. 

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

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

A. CoroUa {or segments) purple or red. 



lingulata, Mez ( Garagudta ling^dd-ta, Lindl. C. 

 sph'iidens, BoucIh^. 0. livgtildta splendens, Hort.). 

 Epiphyte : lvs. many, lanceolate or ensiform, 1% ft. 

 long, remotely toothed : spike becoming drooping, 

 showily red-])racted: 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. 13:10(18. F.S. 11 :1091. -Handsome. Viir.

tricolor, Ruiz Sz Pav. (G. frdgrans, Hort., at least in 

 part. G. grdndis, PJort., in part. G. maculdtn, Hort., in 

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

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

 usually shorter than the stout, erect spike: lowerbracts 

 green streaked with black, upi>er ones red-tinged: co- 

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

 5:402. 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 ^Eehinea ehnruea, Baker {Oanistrum Lin- 

 deiii, Mez. IV'idHlilrinni Lindeni, Rcgel). This species 

 is further mentioned under Nidularium. 



Devansayina.Morr. (Oaragvdfa Prravsaiii\iia,M.ovT.).

 on the back: fls. white, in a dense, oblong spike, the scar- 

 let bracts oval. Equador.
