Ground Cheery. — Cerasus Cha- 

 incecerasus. 



Ground Ivy. — See Glecho^ma. 



GB.OTjyDSE'L.--SeneciovuIgaris. — 

 I mention this troublesome weed, to 

 enfoi-ce upon amateur gardeners the 

 necessity of pulling it up as soon as it 

 appears, without suffering it to open 

 its flowers, lest it should ripen any 

 of its seeds. The plant belongs to the 

 Compositse, and the seeds are each 

 furnished with a feathery wing or 

 pappus, by means of which they are 

 distributed iu all directions. 



Groundsel -TREE. — Bacchans 

 halimifblia. — A shrub with bluish 

 green leaves, and ratter pretty flow- 

 ers, which are produced in autumn. 

 It will grow in any common garden - 

 soil, but it is killed in severe winters, 

 if in an exposed situation. It may 

 be proiJagated by cuttings, which will 

 strike if planted in the open border 

 in autumn ; or by layers. 



Guano. -A new kind of manure, 

 lately introduced from South America. 

 It consists of the dung of sea-fowls, 

 collected from the Guano Islands, on 

 the coast of Peru ; and it is so strong 

 that a table-spoonful of it dissolved 

 in water will go as far as three trowels- 

 ful of horse dung. It may be used for 

 Orange-trees, Pelargoniums, Heart's- 

 ease. Fuchsias, and any other plants 

 requiringrich soil. In general, how- 

 ever, it is most efficacious to grass 

 land, and it may also be used with 

 advantage in a kitchen-garden. In 

 these cases the proportion is four 

 ounces of guano to a gallon of water ; 

 but this is much too strong for green- 

 house plants, and for thern half an 

 ounce of guano to a gallon of water 

 wUl be as strong as it will he safe to 

 give them.

Gu'tta Pe'rcha. — This is a kind 

 of gum somewhat similar to the 

 Caoutchouc or India Rubber, but 

 which possesses the remarkable "phy- 

 sical property of becoming quite soft 

 at the temperature of boiling water, 

 without being in any way adhesive, 

 and on cooling recovering its primi- 

 tive hardness." The Niato or Gutta 

 Percha tree of the ]\Ialay Peninsula, 

 is said by some botanists to be a 

 species of Bassia, but Dr. Lindley 

 pronounces it to be a species of the 

 genus Isonandra, both genera belong- 

 ing to the natui-al order Sapotace?e. 

 ]\Ir. Low, however, thinks that several 

 trees in Borneo will produce a similar 

 juice. The gum is said to be de- 

 posited in layers in the wood, and to 

 be obtained only by cutting down the 

 tree ; but as it is also said to flow 

 when numerous incisions are made in 

 the bark, it is to be hoped that some 

 less wasteful mode of procuring it 

 than cutting down the tree will soon 

 be devised. The words Gutta Percha 

 belong to the Malay language, and 

 signify "ragged gum" — the cA in the 

 word Percha being pronounced as in 

 perch. 



Gymnostachyum. — A canthacece. 

 — A Ceylon plant with inconspicuous 

 yellow flowers, but showy leaves, 

 with milk white midrib, and side 

 veins on a dark green ground. 

 Introduced in 1853. 



Gypsocallis Sal. — Ericacece. — 

 The Moor, or Cornish Heath, sepa- 

 rated from the genus Erica by Salis- 

 bury. — For culture, see Eri'ca. 



Gypso'phila. — Caryophyllacece, 

 or Silenacece. — Small-flowered creep-
