GUAVA 



GUZMANIA 



be potted oflf 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, 



GUAZtJMA (name of Mexican origin). StercuUAcecr. 

 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 Theobroma, but that 

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

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

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

 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. FritiUaria Meleagris. 



GUIZOTIA (after Guizot, the celebrated historian). 

 ComposUa'. 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 Imvo much ornamental value. The 

 plants have vellnw ln-nds, about 2 in. across, with 8 

 broad, 3-toothed mys 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. oldferay DC. Verbesina saliva, 

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

 serrate. B.M, 1017,

GUNNfiRA (J, Ernst Gunner, 1718-1773, was a Swed- 

 ish liishop and botanist, and wrote a local flora). Malo- 

 ragtirets. The little family Haloragacete 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 lvs. 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 : f r. a drupe. They are perennial herbs, 

 and with protection the two following species may be 

 grown even in some of our norilittn states. 



Gunneras are perhaps tlic tiMiih -i ,,\' all lawn foliage 

 plants. To produce sjitislam.i y 'H.-cts, rich, moist 

 ground is indispensable, Thu phmt.s nmst 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 



should l)e provided for. A libera! eovering of leaves or 

 litter. 1m-[<1 in i)lace l.y l>ni>li or hranrhes, will generally 

 keep them from harm. Aj-ply the .-overing 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 diam. and 3-4 ft. tall. S. Brazil. I.H, 

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

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

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



Chil^nsis, Lam. {G. scdbra, Ruiz & Pav.). Not so ro- 

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

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

 Gn, 40. p. 151. G.C, II. 20:425; III. 8:G65.-Longer 

 known in cult. Thrives in drier soil,

GUTIERRfiZIA (personal name), Compdsitm. About 

 18 species of herbs or subshrubs, often resinous, all 

 American, mostly western N. American, They are much 

 hraiif-hed from the base, and have narrow, entire lvs. 

 and clusters of small yellow heads. 



Euthimiae, 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 (>f uliout 9 chaffy scales. N. W. N. Amer. 



GUZMANIA (A. Guzmann, Spanish naturalist), Bro- 

 mclinrt'iF. Includes Caraguata. About 70 tropical 

 American Bromeliads, of which several are fairly well 

 known ornamental glasshoiise subjects. 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 iinited by their 

 edges around the style. Grown in the warmhouse, along 

 with Billbergia and Tillandsia, which see for culture. 

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

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

 Nidularium. For G. LegreUiana, see Hohenbcrgia. G. 

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

 probably an ^chmea, Monogr. by Mez. DC. Monogr.

tricolor, Ruiz & Pav. {G. frdgratis, Hort., at least h> 

 part. G. grdiidis, Hort., in part. G. ynacitldta , Hort., in 

 part. G. mouo.'itdchya, Rxishy). 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, 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 ^Jchmea ebitrnea, Baker {Canistrum' JAn- 

 deni, Mez. NiduUtrium Lindeni, Regel), This species, 

 is further mentioned under Nidularium. 



Devan8ayS.na,Morr. (Caragudta DeransaydnaMorr.) . 

 Livs. about 20, narrow linear or ensiform, brown-striped 

 on the hack: tls. white, in a dense, oblong spike, the scar- 

 let bracts oval. Equador.
