BOTANICAL TERMS. 
513 
Patelliform (patelliformis) ; kneepan- 
shaped, broad, round, thick, convex on the 
lower surface, concave on the other : it is the 
same as meniscoid, but thicker. 
Pectinate (pectinatus) ; comb-shaped, with 
numerous close narrow segments, like the 
teeth of a comb. 
Perfuse (pertusus) ; perforated, or having 
irregular open spaces, so as to appear pierced 
with holes, as in some kinds of leaves. 
Petaloid ( petaloideus) ; petal-like, having 
the colour and texture of a petal : often ap- 
lied to bracts. 
Piliferus ; hair-pointed, differs from setose 
chiefly in having a weak instead of shai'p 
point ; it occurs in many mosses. 
Placentiform (placentiformis) ; placenta- 
shaped, that is, thick, round, and concave, 
both on the upper and lower surface, as in 
the root of the Cyclamen. 
Plane (planus) ; a perfectly even and flat 
surface, which occurs in many leaves. 
Prcegnans ; swollen, protuberant. 
Prcemorse (prcemorsus) ; bitten, differs 
from truncate in the termination being ragged 
and irregular ; the leaf of Caryota urens is 
an example. 
Prismatical (prismaticus) ; prism-shaped, 
that is, having several longitudinal angles, 
with intermediate flat faces, as in the calyx of 
Frankenia pulveridenta. 
Pteras; the term used in composition for 
winged ; thus, dipterus, two-winged ; tri- 
pterus. three-winged ; and so on. Epipterus 
is applied when the wing terminates, and 
peripterus when it surrounds anything. 
Pulvinate (pidvinatus) ; cushion-shaped, 
convex and rather flattened. 
Pungent ( pungens) ; sharp, terminating 
gradually in a hard sharp point, as in the 
leaves of many plants. 
Pyriform (pyriformis) ; pear-shaped, dif- 
fering from turbinate in being a more elon- 
gated figure ; this form is exemplified in 
many pears. 
Pyxidate (pyxidatus) ; shaped like a box. 
Quaternate ; in fours; applied when four 
leaflets spring from the same point. 
Quinate; in fives ; applied when five leaflets 
spring from the same point. 
Ramose (ramosus) ; branched, having 
many divisions ; if they are small, the term 
ramulosus is used ; if the tendency is but 
slight, sub -ramosus ; if in a very great degree, 
the term ramosissimus is employed. 
Regular (regularis) ; when all the cor- 
responding parts — that is to say, all the petals 
of a flower, for instance — are symmetrical ; 
the buttercup is a regular flower. 
Repand (repandus) ; having an uneven 
outline or margin, with slight concavities and 
convexities, as observed in some leaves. 
48. 
Retuse (retusus) ; terminating in a round 
end, the centre of which is depressed, as in 
the leaf of Vaccinium Vitis-idaia. 
Rimose (rimosus) ; chinky, having a longi- 
tudinal fissure or fissures. 
Ruminate (ruminatus) ; applied to hard 
bodies pierced in various directions by narrow 
cavities filled with dry cellular matter, as in 
the albumen of the nutmeg. 
Rostrate (rostratus, rostellatus) ; beaked, 
terminating gradually in a hard long straight 
point, as in the seed-pod of a radish : the term 
mostly applies to some elongation of the seed- 
vessel. 
Saccate (saccatus) ; pouch-shaped. 
Scrotiform (scrotiformis) ; pouch-shaped, 
hollow, and resembling a double bag. 
Scutate (scutatus, scutiformis) ; buckler- 
shaped, having the figure of a small round 
buckler ; lens-shaped with an inverted rim. 
Scutelliform (scutelliformis) ; differs from 
patelliform in being of an oval figure, not 
round. 
Sellceform (sellceforynis) ; saddle-shaped, 
oblong, with the sides hanging down as the 
flaps of a saddle. 
Semiterete (semiteres) ; half-terete, that is, 
round on one side, and flat on the other. 
Serrate (serratus) ; saw-edged, having 
sharp straight-edged teeth pointing towards 
the apex ; applied to the margins of leaves : 
if the serratures are again serrated it is called 
biserrate, or duplicato-serrate. 
Setose (setosus, setiger) ; bristle-pointed, 
terminating gradually in a very fine sharp 
point, as in the leaves of some mosses. 
Simple (simplex) ; scarcely divided or 
branched at all : simplicissimus expresses ab- 
solute simplicity. 
Sinuate (sinuatus) ; having an uneven 
margin with deep concavities and convexities, 
as in the leaf of the common oak. 
Sinus; the indentation or recess formed 
when a leaf or other body is divided into lobes. 
Spheroidal (spheroideus) ; having a sphe- 
rical figure a little depressed at each end ; 
applied to a solid body. 
Spiral (spiralis) ; lengthenec"., and twisted 
like a corkscrew. 
Stellate (stellatus) ; divided into segments, 
radiating from a common centre. 
Strombuliform (sirombidiformis); alength- 
ened spirally twisted figure, resembling the 
convolutions of a shell called a strombus ; it 
occurs in some seed-pods. 
Succisus ; bitten ; the same as prcemorse. 
Supradecompound (supradecompositus) ; 
having several series of divisions or ramifica- 
tions, that is, when the primary divisions are 
divided, and these again divided, and so on ; 
it is chiefly applied to leaves. 
Taper (teres) ; emploj'ed in contradistinc-
