hyacinthina, Herb. Bulb globose : Ivs. 6-9 in. long, 

 ! 3 in broad, rounded at the base to a channeled peti- 

 : ole as Ions as the blade : scape 1-2 ft. long : pedicels 

 'aone or very short : stamens much shorter than the 

 'segments. B.R. 2:163 (as Amaryllis hyacinthina. 

 Upper segments tinged blue, lower ones nearly white). 

 'J H III. 31:371. Var. maxima, Gn. 50, p. 209, is prob- 

 ably the best garden form. Called Blue Amaryllis " in 

 'some catalogues. 



AA. Stigma distinctly 3-cut. 



Blumenavia, K. Koch & Bouche. Bulb ovoid : Ivs. 

 ! 4-5 in. long, cuneately narrowed to a petiole, shorter 

 than the blade: scape 6-8 in. long: pedicels % in. long: 

 stamens as long as the perianth. B.M. 5666 (veins rose- 

 colored). R.H. 1867:32. Gn. 50:1083 (veined and flushed 

 with rose). 



GRINDELIA (Prof. Hieronymus Grindel, of Riga and 

 Dorpat) . Compdsitfe. This genus contains 2 plants from 

 which a fluid-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 



' l%-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 often have a sticky balsam, espe- 

 cially the heads before and during flowering, whence 

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

 G. robusta, 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 firm or rigid leaves. 



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

 division, cuttings or seed. G. squarrosa is hardy in the 

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



1 wild places and trying situations. J. W. Manning 

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

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

 ately rich soil. In California it is common 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 % in. long. 



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

 ft. high : outer akenes usually squarely truncate and 



' even at summit B.M. 1706. 



robusta, Nutt. GUM-PLANT. Herbaceous: Ivs. larger 

 and more rigid : akenes all, or some outer ones, 1-toothed 

 or bordered at the summit. Fls. throughout the Califor- 

 nian winter. Collected stock is offered. W. M. 



GKISELtNIA (after Franc Griselini, Venetian bota- 

 nist, middle of eighteenth century ) . Including Decostea . 

 Corndcece. This includes a tree and a shrub with large, 

 glossy, laurel-like foliage, rarely cult, in 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 Ivs. alternate, ofteninequal-sided, 

 leathery: fls. minute, in glabrous or 

 pubescent racemes or panicles. 



littoralis, Raoul. Tree, 30 ft. high: Ivs. ovate or ob- 

 long, wedge-shaped or narrowed into a petiole: veins 

 obscure beneath. New Zealand. 



lucida, Forst. f. Shrub, 10-12 ft. high: Ivs. obovate 

 or oblong, very unequal at the base ; veins distinct be- 

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

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

 9. lucida is prized 'in Europe for apartments. Showy. 

 Requires shade and moisture. 



GKOMWELL. Lithospermum. 



GROUND CHERRY is Phy salts; in the Old World 

 Prunus Chamwcerasus. Ground Hemlock or Ameri- 

 can Yew, is Taxus Canadensis. Ground Ivy. Nepeta 

 Glechoma. Ground Laurel. Old World name for Epi- 



gcea repens. Groundnut, Apios and Panax ; also Old 

 World name for peanut or goober (Arachis). Ground 

 Pine, Lycopodium. Ground Fink, Phlox subulata. 



GROUNDSEL. See Senecio. Groundsel Tree. Bac- 



charis halimi folia. 



GRUMICHAMA. Eugenia Srasiliensis. 

 GRUMlLEA. All referred to Psychotria. 



GUAlACUM (native West Indian name). Zygophyl- 

 lacece. Guaiacum is kept in every good drug store, 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 : Ivs. 

 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 4-5, broadly obovate ; stamens 8-10, 

 inserted in the short, inconspicuous disk. 



officinale, Linn. Middle-sized or low tree, inhabiting 

 arid plains from the Fla. keys to Venezuela. Lfts. in 

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



GUAM, ISLAND OF. See Ladrones. 



GUAVA (species of Psidium, 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 tropics it is at home, and succeeds admi- 

 rably on any soil not too 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 best for all purposes, and make the 

 finest of jelly and preserves. The Cattley and the Chi- 

 nese are now cultivated in Florida; when dormant they 

 will stand a temperature as low as 22 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 fine variety recourse must be had to grafting or

propagating from cuttings. Grafting is performed after 

 the usual methods Propagation by cuttings is difficult, 

 but possible, and the best results seem to be had 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
