INTRODUCTION TO BOTANY.

Gooseberry, Grossularia ; also in fruit, as a cluster of Grape* or Cur-rants.

4th. PANrcuiA. A mode of flowering in which the fructification isdisposed on, foot-stalks, variously subdivided; as in Poa, MeadowGrass.

5th. The Spicule are the single spikelets at the termination ofeach branch of the panicle.

6th. Thyrsus. A mode of flowering in which a panicle contract,into an oval or egg-shaped form ; as exempl.fied in the Lilac.

7th. Umbella. A mode of flowering in which a number of slenderfoot-stalks proceed from the same centre, and rise to an equal height,so as to form an even and flat surface at top, as is exemplified in Co-rium maculatum, Hemlock.

8th. Cvma. A mode of flowering very like the Umbel, in which anumber of slender foot-stalks proceed from a common centre, and riseto the same height; but, unlike the Umbel, the secondary or partialfoot-stalks are disposed without any regular order : this is seen in Vi-burnum, Laurus Cerasus, Sec. &c.

9th. Corymbus. A mode of flowering in which the partial flower-stalks are produced along the common stalk on both sides; and thoughof unequal lengths, rise to the same height, so as to form a flat andeven surface at top. This is exemplified in Uieris, Candytuft.

10th. Capitulijm. —A mode of flowering in which many flowers arecollected into a head at the extremity of a summit of the foot-stalk ;as in Asperula, VVoodroof.

The SEEDS. These also vary in shape, which will be illustratedhereafter in the List of Botanical Definitions.

Receptacle (Receptaatlum). The base of the fructification, whichsupports the whole.

It is termed Proper when it supports only a single fructification, asin Dianlhus.

Or Common, when it supports a number. Of this kind are thosewhich support the parts in the compound flowers, as in the class Syn-geneiia.

Bud (Gemma) is the hybernaculurn of the leaves, and formed inthe stammer's growth. These consist of two binds: the one containingleaves alone, which are known by gardeners as Weod-buds; the othercontains the bloom, which is distinguished by the name of Fruit-buds.The outer coat of the former consists of scales, which fall off; butin the latter it forms in many cases the calyx, as above described.

Vernation (Fernalio). The disposition of the leaves in the bud be-fore they are unfolded.

Measures are sometimes referred to in botanical description. Adescription of these will be found in the succeeding pages.

For a further and more general explanation of thedifferent formsand characters of the above, I shall refer the student to the followingGlossary of
