i; Sutherland!, the only species, is a beautilul 

 and distinct moderate-sized tree, found in the 

 mountains about Port Natal. Its foliage is sim- 

 ilar to a Pelargonium. The flowers are borne m 

 dense axillary racemes, and are of a brilliant 

 crimson color, giving to the tree a very hand- 

 some appearance. 



Orias. Anchovy Pear. From (/ran, to eat ; the 

 fruit being eatable. Linn. Poli/andria - Mono- 

 gynia. Nat. Ord. Barrtngtonhuxce. 



G. cauliflora, the only species, is a tall, un- 

 branched tree, with leaves two or three feet 

 long, and bearing large whitish flowers, which 

 proceed from the stem. The fruit has much the 

 taste of the Mango, and is highly esteemed in 

 the West' Indies, where it is indigenous. The 

 tree is largely cultivated, not only for its fruit, 

 but for its highly ornamental character. 



Oriffinia. Named after W. Griffin, a patron of 

 botany. Linn. Hexandria-Monogynia. Nat. Ord. 

 Amaryllidacece. 



A small genus of handsome bulbous plants 

 from South America. The flowers are of a beau- 

 tiful purple, borne in an umbel. They require 

 green-house treatment, and should have com- 

 plete rest during winter. In March re-pot them, 

 and they will immediately commence growth, 

 and will require plenty of heat, light, air, and 

 water. They are increased by offsets. Intro- 

 duced in 1822.

 Nat. Ord. Zygophyttacea:. 



A genus of ornamental trees with pretty blue 

 flowers. G. offirinnle furnishes the well-known 

 wood Lignum Vita;, 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.

G. avfMnna, the only species, is a tree of me- 

 dium 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 Pome- 

 granate.

with large, handsome, glossy leaves and showy 

 white flowers, sometimes five or six inches 

 across, tinged with pink, not unlike those of 

 some Magnolias. They are disposed in racemes 

 or umbels at the ends of the twigs. The fruits 

 are somewhat fleshy and apple-like. G. gracillima 

 is a magnificent plant, introduced from the 

 United States of Columbia by M. Roezl. It has 

 a smooth, slender, woody stem. 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 solitary or in pairs, 

 four inches in diameter, of a beautiful rose 

 color, consisting of eight petals, with the yellow 

 incurved staminal tube bearing numerous pur- 

 ple anthers in a ring of an inch or more across. 

 This species was introduced in 1874. Propa- 

 gated by cutting of well-ripened wood.

Guzmannia. Named after A. Guzman, a Spanish 

 naturalist. Linn. Hexandria-Monogynla. Nat. Ord.

Green-house perennials, natives of South 

 America. G. tricolor is a pretty species, with 

 flowers on a spike, concealed by the bracts, the 

 lowermost of which are green, while the others 

 are scarlet. It requires ordinary green-house 

 treatment. Propagated by suckers. 



Gymnema. From gymnos, naked, and nema, a 

 filament; in reference to the stamens. Linn. 

 Pentandria-Digynia. Nat. Ord. Asdepiadacecv. 



G. ladifentm is the Cow Plant of Ceylon, the 

 milk of which is used as food by the natives. 

 The species are green-house evergreen twiners, 

 producing clusters of yellow flowers from the 

 axils of the leaves. They are allied to the Ste- 

 phanotis, and require the same treatment. 



Gymnocladus. Kentucky Coffee Tree. From 

 gymnos, naked, and klados, a branch; in refer- 

 ence to the soft young wood, devoid of buds. 

 Linn. Dmcia-Decandria. Nat. Ord. Fabacece. 



G. Canadensis, the only species, is an orna- 

 mental, hardy, deciduous tree, growing fifty to 

 sixty feet high. It is one of our most beautiful 

 shade trees, and is planted to a considerable 

 extent on the streets in Washington, D. C. ; 

 it is also valuable for its hard tough timber. 

 Common from New York, South and West. 



Gymnogramma. From gymnos, naked, and 

 gramma, writing; in reference to the spore 'cases. 

 Linn. Oryptogamia-Fdices. Nat. Ord. Polypodi- 

 acece. 



A genus of very beautiful Ferns, requiring 

 the warm green-house to grow them. In some of 

 the species the under surface of the fronds is 



Erofusely covered with a rich yellow or white 

 irinose powder, which gives them the name of 

 Gold or Silver Ferns, so frequently seen in cul- 

 tivation, on account of the beauty of their 

 fronds. This genus contains two of the very 

 few known annual Ferns, G. chwrophylla, a West 

 Indian plant, and G. leptophylla, which is found 

 scattered over nearly the whole of the temperate 

 regions of the globe. 



Gymnostachyum. Fittonia. From gymnos, 

 naked, and stachys, a spike. Linn. Diandria- 

 Monogynia. Nat. Ord. Acanlhacece. 



This genus consists of a few dwarf herbaceous 

 plants, of prostrate habit, with leaves beautiful- 

 ly veined with white or red. The species are 

 considerably grown for Wardian cases or Ferner- 

 ies, for which purposes they are well suited. 

 When well grown they make splendid specimen 

 plants for the hot-house. They should be grown 

 in a humid atmosphere. Propagated by cuttings.
