GKINDfiLIA (Prof. Hieronymus Grindel, of Riga and 

 Dorpat). CoiHpiUit'V, This genus contains 2 plants from 

 which a Iluid-extract is obtained that is used externally 

 against poisoning by " poison ivy." They are hardy plants 

 sometimes cult, for their showy yellow fls., which are 

 II2-2 in. across and borne freely all summer. A genus 

 of about 14 species of American herbs, sometimes 

 shrubby, of coarse habit, mostly natives of the U. S. 

 west of the Mississippi. Lvs. sessile or partly clasping 

 and usually serrate and rigid : heads terminating the 

 branches. The plants uften have a sticky balsam, espe- 

 cially the heads before and during flowering, whence 

 they are called "Gum-plants" in California, particularly 

 G. robu-sta, which is the common one. The 2 species de- 

 scribed below have roots that are perennial and short- 

 lived, but sometimes annual. These plants are also 

 wholly glabrous, and have Arm or rigid leaves. 



Griudelias are of the easiest culture, and are prop, by 

 division, cuttings or seeil. O. squan-osa is hardy in the 

 East: G. robustn is sold in Calif. They are best for 

 wild places and trying situations. J. 'SV. Manning 

 says that G. sqnarrosa grows freely in all soils. J. W. 

 Keller writes that it does best in a light, open, mndcr- 

 ately rich soil. In Califi>rnia it is comiuou on dry hills. 

 According to John S. Wright, both species grow in salt 

 marshes and on alkaline soil, being indiscriminately 

 gathered for medicinal purposes. The extract is also 

 tonic and sedative, and is used in asthma. The rays are 

 numerous, sometimes 30, about ^2 in. long. 



gquarrdsa, Dunal. Shrubby, branched from base. 1-2 

 ft. high : outer akenes usually squarely truncate and 

 even at summit B.M. 1706. 



robiista, Xutt. Gum-Plant. Herbaceous: lvs. larger 

 and more rigid: akenes all, or some outerones, 1-tuothed 

 or bordered'at the summit. Fls. throughout the Califur- 

 nian winter. Collected stock is offered. -^^ jj_ 



GRISELINIA (after Franc Griselini, Venetian bota- 

 nist, middle of eighteenth century ) . Including l}t'cost>:a . 

 Corndce<v. This 'includes a tree and a shrub with large. 

 glossy, laurel-like foliage, rarely eult. iu the South, and 

 nearly hardy at Washington. A genus 

 of 8 species of trees, shrubs or climb- 

 ers from New Zealand. Chili and Brazil, 

 with lvs. alternate, often inequal-sided, 

 leathery: fls. minute, in glabrous or 

 pubescent racemes or panicles. 



littorMis, Raoul. Tree, 30 ft. high: lvs. ovate or iil'- 

 long. wedge-shaped or narrowed into a petiole: veii.s 

 obscure beneath. New Zealand. 



liicida, Forst. f. Shrub. 10-12 ft. high: lvs. obovate 

 or oblong, verv unequal at the base: veins distinct be- 

 neath. New Zeal. Not cultivated here. Var. macro- 

 phylla (G. macropJiffUa, Hort. ) is a large-leaved form. 

 G. IticiJa is prized "in Europe for apartments. Showy. 

 Requires shade and moisture.

GUAIACUM I native West Indian name). Zygophyl- 

 hlcva'. <.iuaiacuin is kept in every good drug sture, and 

 the tree which produces the resin used in medicine has 

 a hard, heavy wood, used for blocks and pulleys, lulers, 

 etc. It is cult, to a very slight extent in S. Calif, and 

 in tropical Fla. for ornamental value. The genus has 

 8-10 species of trees or shrubs, mostly tropical Ameri- 

 can, and all have hard wood and abundant resin : lvs. 

 opposite, abruptly pinnate, leathery : Ifts. 2-14, entire: 

 peduncles borne in pairs between the deciduous stip- 

 ules, 1-fld.: fls. blue or purple: sepals 4-5, deciduous, 

 unequal ; petals 4-.1, broadly obovate ; stamens S-10, 

 inserted in the shurt, inconspicuous disk. 



oificinS-le, Linn. Middle-sized or low tree, inhabiting 

 arid ^tlains from the Fla. keys t" X'mezuela. Lfts. iu 

 pairs, evergreen, a quarter to half an inch long.

GUAVA (species of Psidluw, which see). Fig. 1007. 

 The Guava, in its various species, is so easily cultivated 

 and spreads so readily from seeds that it is almost a 

 ■weed in tropical countries. In Florida and other sec- 

 tions near the trojiics it is at home, and succeeds admi- 

 rably on any soil nut t<>o wet. It usually bears in its sec- 

 ond year from seed, or after frosting down, hence if a 

 winter passes without seriously damaging the tops, a 

 considerable amount of fruit is produced the succeeding 

 summer and autumn. The strictly tropical species and 

 varieties are the lifst for all purposes, and make the 

 finest of .icily and i)reserves. The Cattley and the Chi- 

 nese are now cultivated in Florida; when dormant they 

 will stand a temperature as low as 2'2'^ F. The foliage of 

 these two sorts is very ornamental, being a rich, glossy 

 green, not unlike that of Camellia Japonica. 



The Guava is most readily propagated from seed, but 

 is quite variable, hybridizing so easily that to secure a 

 certain line variety recourse must Vie had to grafting or

propairatiug from cuttinirs. Grafting is performed after 

 the us\ial methods. Propagation by cuttings is difficult, 

 but possible, and the best results seem to be bad from 

 half-ripened -wood, using bottom heat in a frame or 

 house. Large cuttings are occasionally rooted in the 

 open ground, after the same method of rooting figs or 

 willows. If grown from seed, the young plants should
