and from one to two inches in diameter. Tliey 

 are easily cultivated, and are increased by 

 seeds or cuttings. 



Griseli'nia. Named in honor of Frank Griselini, 

 an Italian botanist. Nat. Ord. Cornaceas. 



A small genus of evergreen shrubs, nearly 

 allied to Aucuba which they resemble in habit. 

 They have shining coriaceous leaves, and 

 small inconspicuous flowers, produced in ter- 

 minal panicles. They are natives of New 

 Zealand, Chili, and Brazil, and are of com- 

 paratively recent introduction. Their hardi- 

 ness has not been tested in this country, but 

 it is not likely they would endure the rigors 

 of our Avinters, north of Virginia. 



Gromwell. See Lithospermum. 



Grono'via. Named in honor of Dr. Gronovius, 

 a botanist at Leyden, and a friend of Linnteus. 

 Nat. Ord. Loasacece. 



G. scandens, the only known species, is a 

 scandent herb resembling the Bryony. It is 

 found from Texas to Venezuela, and was in- 

 troduced in 1751, but is little cultivated. 



Grosaularia'ceee. A natural order, now in- 

 cluded by Bentham and Hooker with Saxifra- 

 gacece. 



Ground Cherry. See Physalis. 



Ground Hemlock. See Taxiis.

Gua'iacum. Lignum Vitae. The original name 

 in South America. Nat. Ord. ZygophyllacerB. 



A genus of ornamental trees with pretty 

 blue flowers. G. officinale furnishes the well- 

 known wood Lignum Vitce, and also the drug 

 known as Gum Guaiacum, which is procured 

 by notching the trunk, and allowing the 

 exuding juice to harden. It is a native of the 

 West Indies. 



Guava. See Psidium. 



Guelder Rose. Viburnum opulus. 



Guernsey Lily. Nerine Sarniensis. 



Guevi'na. The native name. Nat. Ord. Proteacem. 

 G. Avellana, the only species, is a tree of 

 medium size, a native of Chili and Peru. The 

 flowers are in simple, erect racemes two to 

 four inches long, and these are succeeded by 

 round edible drupes, inclosing almond-like 

 seeds, known as Chilian nuts. The latter 

 have an agreeable, somewhat oily taste, while 

 the fleshy part is made a substitute for the 

 Pomegranate. Syn. Quadria. This tree is 

 hardy in the Southern States. 



GuUie'lma. Named in honor of Queen Wilhelmine 

 Carolina of Bavaria. Nat. Ord. Palmacece. 



A genus of palms confined to the tropical 

 regions of South America, and containing three 

 species which have tall, slender trunks armed 

 with exceedingly sharp black spines. The large 

 pinnate leaves have spiny leaflets and foot- 

 stalks. G. specioaa, the Peach Palm, is cul- 



GUZ 



tivated on the banks of the Amazon and Rio 

 Negro. Its edible fruits, which are about the 

 size of Apricots, and bright-scarlet in color, 

 are borne in large drooping bunches, and form 

 a large portion of the food of the natives. The 

 young plants make very handsome specimens 

 for the green-house.

Guinea Hen Flower. A name given to Friiil- 

 laria Meleagris. 



Gum. A vegetable secretion which may be 

 detected in the sap of most plants, and which 

 is excreted by many, and hardens on their 

 surface. 



Gum Cistus. Cistus ladaniferus. 



Gum Guaiacum. See Guaiacum. 



Gum Tragacanth. Sterculia Tragacantha. 



Gum Tree. Various species of Eucalyptus, 

 which see. 

 Sour. Nyssa muUiflora 

 Sweet. Liquidambar styraciflua. 



Gu'nnera. In honor of J. E. Gunner, a Swedish 

 bishop and botanist. Nat. Ord. Haloragacem. 

 A small genus of half-hardy herbaceous 

 plants, natives of South America and the 

 Sandwich Islands. G. scabra, has been intro- 

 duced into the English gardens, and is re- 

 markable for its ragged, rhubarb-like leaves, 

 which are fully three feet across, borne on 

 stout, thorny stems. The plant is also notable 

 for its remarkable size ; a good specimen 

 being from four to five feet high, and 

 eight to ten feet in diameter, and forming 

 an excellent subject for the sub-tropical 

 garden. It is propagated by seeds, or careful 

 division. 



Gusta'via. Named after Gustavus III. of 

 Sweden. Nat. Ord. Barringtoniaceoe. 



A genus of fine evergreen trees and shrubs, 

 with large, handsome, glossy leaves and 

 showy white flowers, tinged with pink, some- 

 times five or six inches across, and not unlike 

 those of some Magnolias, disposed in race- 

 mes or umbels at the ends of the twigs. The 

 fruits are somewhat fleshy and apple-like. 

 G. gracillima, has a smooth, slender, woody 

 stem, and is a magnificent ornamental plant, 

 introduced from the United States of Colum- 

 bia by M. Roezl. The flowers grow from the 

 axils of the leaves of the young plants, and 

 from the leafless parts of the trunk in the 

 older ones. They are solitaiy or in pairs, 

 four inches in diameter, of a beautiful rose 

 color, consisting of eight petals, with the 

 yellow incurved staminal tube bearing numer- 

 ous purple anthers in a ring of an inch or 

 more across. This species was introduced in 

 1874, and is propagated by cuttings of well- 

 ripened wood. 



Gutta Percha. See Isonandra. 



Guttatus. Spotted. 



Guzma'nnia. Named after A. Guzman, a Span- 

 ish naturalist. Nat. Ord. BromeliacecB. 



Green-house perennials, natives of South 

 America. G. tricolor is a very handsome 

 species, with flowers on a spike, concealed by 

 the bracts, the lowermost of which are green, 

 while the others are scarlet. It requires or- 

 dinary green-house treatment, and is propa- 

 gated by suckers.
