formed of wood. 
Medulla ; the pith ; the centre or heart of 
the vegetable body, within the wood. 
Medullary rays; lines radiating through 
the wood from the centre to the circumfer- 
ence ; they have been so called, upon the pre- 
sumption that they proceed from the pith, but 
few of them have been fairly traced to it. 
JMerithallus ; a term applied to the inter- 
nodes, or spaces between the joints of the 
stem. 
Naked bulb ; a bulb formed of distinct and 
fleshy scales, without a united membranous 
covering ; the bulbs of the lily are of this 
kind. 
Node; the part of the stem from whence 
the leaves proceed; the spaces between them 
are called internodes. 
Offset (propacuhmi) ; a short lateral 
branch produced in herbaceous plants ; it is 
terminated by a cluster of leaves, and capable 
of taking root when separated from its parent ; 
is nearly related to the runner : some kinds 
of sempervivum produce this kind of branch. 
Peridroma ; a term applied to the petioles, 
or stipes of ferns. 
Pilulifera ; bearing little balls or globe- 
shaped bodies. 
Pith ; the central spongy cellular substance 
of the root and stem, the medulla. 
Plateau ; a term applied to the corm. 
Propacidum ; a term applied to the offset. 
Pseudo bidb ; an enlarged aerial stem, re- 
sembling a tuber with an extremely hard 
cuticle, and retaining on its surface the scars 
of leaves which it has once borne : this term 
is applied to the bulb-like stems of orchids. 
Rami; the branches or divisions of the 
stem : ramtdi, are branchlets, or branches of 
smaller size. 
Ramilles ; a term applied to the smaller 
twigs or branches. 
Rhizoma; the root-stock, a prostrate thick-

young branches : the root-stock is common 
among irises. 
Runner {sarmentum) ; a prostrate filiform 
stem, forming roots, and a young plant at the 
extremity, and there throwing out other run- 
ners : the strawberry is a good example.

Sarmentum ; a runner ; a peculiar kind of 
prostrate stem.

Scoberia ; a term applied to the rachis in 
the spikelets of grasses, which has a toothed 
flexuose appearance. 
Silver grain; a term applied to the medul- 
lary rays, which often have a silvery appear- 
ance, as when appearing in the wood of the oak. 
Sobole ; a slender, creeping stem, growing 
horizontally below the surface ; the suckers of 
trees and shrubs are sometimes so called. 
Spines; small indurated and pointed pro- 
jections from the branches, having the same 
woody character. 
Sjrinous ; having or producing spines. 
Stemless; applied to plants apparently des- 
titute of an aerial stem, or having but a very 
short stem. 
Stipes ; a secondary stem, supporting the 
leaves of palms ; the petiole of the frond in 
ferns ; the trunk that supports the pileus or 
cap of fungi. 
Stolone (stolo) ; a creeping above-ground 
stem, producing roots at intervals. 
Subterranean stems ; underground stems, 
such as the corm, the tuber, &c. 
Sucker (surculus) ; a branch produced from 
beneath the surface, and growing erect, when 
it emerges from the soil. 
Suffruticose ; sub-shrubby, that is, having 
branches of a w r oody texture, which perish 
annually either wholly or in pai't. 
Surculus ; the sucker ; a branch produced 
beneath, but rising above the soil. 
Tegmenta ; the scales of the bud. 
Trailing stem ; a long slender stem, which 
neither twines, nor. climbs, nor roots in the 
ground like the creeping stem, but spreads 
about on the surface of the soil. 
Trunk (truncus) ; the principal stem of a tree. 
Tuber ; an annual, thickened subterranean 
stem, as the potato : tuberculum is a small 
tuber. 
Tunic ; the thin membranous scales that 
cover tunicated bulbs. 
Tunicated bulb ; a bulb covered with co- 
hering outer membranous scales, as in the 
onion. 
Turio ; a stem partly developed, covered 
with scales, as the young stems of asparagus. 
Twigs; ulterior ramifications of the roots 
and branches. 
Twining stem ; a slender stem which 
ascends by twining spirally round other plants, 
or surrounding objects: some twine from left 
to right, following the apparent motion of the 
sun ; and others twist in a contrary direction. 
Vimineus ; slender, flexible. 
Vine (yiticida) ; a trailing stem which does 
not produce roots in ordinary cases. 
Virgate ; slender but less flexible than 
vimineus.
