GRINDELIA 



GUAVA 



Grindelias are of the easiest culture. They are propa- 

 gated by division, cuttings or seed. G. squarrosa is 

 hardy in the East: G. robusta is sold in California. 

 They are best for wild places and trying situations. G. 

 squarrosa grows freely in all soils but it does best in a 

 light, open, moderately 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 thirty, 

 about K-inch long. 



squarrSsa, Dunal. Shrubby, smooth, branched from 

 base, 1-2 ft. high: Ivs. dark or bluish green with clasp- 

 ing bases: fl.-heads sticky: outer achenes usually 

 squarely truncate and even at summit. Manitoba to 

 Mex. B.M. 1706 (as Donia squarrosa). Mn. 10:145. 



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

 and more rigid, broadly cordate-oblong, obtuse: achenes 

 all, or some outer ones, 1-toothed or bordered at the 

 summit. Flowers throughout the Californian winter. 

 Collected stock is offered. 



patens, Greenm. (G. robusta yar. patens, Gray). A 

 stiff erect perennial with many single-headed branches: 

 Ivs. rough-hairy, narrowly oblanceolate, toothed: 

 heads about 1 in. wide, the achenes thin, obcordate at 

 the summit. Calif. G.C. III. 27:59.

GRISEBACHIA: Howea. 



GRISELINIA (after Franc Griselini, Venetian bota- 

 nist, middle of eighteenth century). Including Deeds- 

 tea. Cornacese. Woody plants with large, glossy, laurel- 

 like foliage, rarely cultivated in the South, and nearly 

 hardy at Washington. 



Trees, shrubs or climbers from New Zeal., 

 Chile and Brazil, with Ivs. alternate, often 

 unequal - sided, thick and leathery: fls. 

 minute, in glabrous or pubescent racemes 

 or panicles; calyx very small, 5-toothed, the petals 5, 

 imbricated; stamens 5, with subulate filaments: fr. 

 baccate, 1- or rarely 2-celled. Six or seven species. 

 Related to Garrya, from which it differs in the alternate 

 Ivs. Little cult, in Amer. 



littoralis, Raoul. Tree, 30-50 ft. high, with brown- 

 hairy twigs: Ivs. ovate or oblong, wedge-shaped or nar- 

 rowed into a petiole; veins obscure beneath: fls. in 

 axillary panicles, equaling or slightly shorter than the 

 Ivs. New Zeal. G.W. 14, p. 323. 



lucida, Forst. f. Shrub, 3-25 ft. high: Ivs. obovate 

 or oblong, very unequal at the base; veins distinct 

 beneath: fls. in axillary panicles, usually shorter than 

 the Ivs. New Zeal. Not cult, in Amer. Var. macro- 

 phylla (G. macrophylla, Hort.), is a large, more orbicu- 

 lar-lvd. form. G. lucida is prized in Eu. for apart- 

 ments or residences. Showy. Requires shade and 

 moisture. Sometimes epiphytic. ff. TAYLOR.! 



GROMWELL: Lithospermum. 



GROSSULARIA (from grossulus, a small fig, from 

 the resemblance of the fruit). Saxifragdcese. An old 

 name for the gooseberries recently (N. Amer. Fl. 22, 

 pt. 3. 1908) reinstated by Coville and Britton as a 

 genus coordinate with Ribes, the currants. As dis- 

 tinguished from Ribes, Grossularia is defined by the 

 flowers having an evident hypanthium or cup-shaped 

 receptacle, the pedicels not jointed and the fruit not 

 disarticulating, different disposition of bractlets on 

 the pedicel, and the plants bearing spines at the 

 nodes. Under this disposition, the English gooseberry 

 becomes G. redinata, Mill, or G. Uvacrlspa, Mill., 

 and the native gooseberry of the Downing type is G. 

 hirtella, Spach. See Ribes. L H. B. 



GROUND CHERRY: Physalis; in the Old World 

 Primus Chamsecerasus. Ground Hemlock or Ameri- 

 can yew: Taxus canadensis. Ground Ivy: Nepeta 

 Glechoma. Ground Laurel: Old World name for Epi- 

 gsea repens. Groundnut: Apios and Panax; also Old 

 World name for peanut or goober (Arachis). Ground 

 Pine : Lycopodium. Ground Pink : Phlox subulata. 



GROUNDSEL: Senecio. Groundsel Tree: Baccharis fialimi- 

 folia. 



GRUMICHAMA: Eugenia brasiliensis. 



GUAIACUM (W. Indian name). Zygophylldcese. 

 Guaiacum (gwai-a-cum) is kept in drugstores, and 

 the tree which produces the resin used in medicine has 

 a hard, heavy wood. Both the species below are the 

 source of the lignum-vitse of commerce which is used 

 so extensively for blocks and pulleys, rulers, and the 

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

 in Trop. Fla. for ornamental value. The genus has 

 about 4 species of trees or shrubs, Trop. American, 

 and all have hard wood and abundant resin: Ivs. oppo- 

 site, abruptly pinnate, leathery; Ifts. 2-14, entire: 

 peduncles borne in pairs between the deciduous stip- 

 ules, 1-fld.; fls. blue or purple, not showy; sepals 4-5, 



1769. Cattley guava. ( X 1 A) 



deciduous, unequal; petals 4-5, broadly obovate; 

 stamens 8-10, inserted in the short, inconspicuous disk. 



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

 arid plains from the Fla. keys to Venezuela: Ifts. in 

 pairs, evergreen, J^-J^in. long, obovate or oval, blunt: 

 sepals oval, hairy, thrice exceeded by the petals. 



sanctum, Linn. Similar in aspect, but the Ivs. 

 obliquely lanceolate-elliptic, and the smooth sepals 

 about half as long as the petals. W. Indies. Not 

 much cult, in Amer. The wood of both species is very 

 valuable. N. TAYLOR.! 



GUAR. An annual forage plant (Cyamopsis tetragono- 

 loba, Taub.), of the Leguminosa?, has been tried some- 

 what in this country with promise. It appears to be 

 adapted to the warmer parts of the country, requiring 

 about the same conditions as the cowpea. It is from 

 India. 



GUAVA. The name guava is applied to the fruit of 

 various species of Psidium, frequently with the addi- 

 tion of a qualifying word such as apple, pear, Cattley, 

 to distinguish different species and varieties. In Spanish 

 it is guayaba, in Portuguese goiaba, and in French 

 goyave (the plant goyavier). In Brazil the name araca, 

 with qualifying words, is applied to a number of wild 

 species.
