8 ANALYTICAL ARRANGEMENT OF BOTANICAL TERMS. 
FLOWER. ee ; 
Parts. — Receptacle, the part upon which the several organs 
of the flower are inserted. 
Calyx, She the exterior floral envelope. 
Corolla, the interior ficral envelope. The calyx and 
corolla constitute the Jrotecting organs, sometimes called 
pevianth, 
Stamens Vp the fertilizing organs. 
Pistils NW the seed-bearing organs. The stamens and pistils 
constitute the essential organs. 
Kinds. — Symmetrical, ee same number in each set of 
° 
organs; wnsymmetrical, different number. 
Complete, Se all the sets present; izcompiete, some sets 
wanting. 
: : aMEN 
sepals and petals uniform ; irregular, O60) 
sepals or petals unlike, 
Regular, 
Perfect, stamens and pistils both present ; imperfect, one set 
absent. 
Staminate, with stamens only; Aistil/ate, with pistils only; 
neutral, with neither. 
Monecious, staminate and pistillate un same plant; diecious, 
on different plants. 
Dichlamydeous, having calyx and corolla ; monochlamydeous, 
having calyx only; achlamydeous, having neither. 
, Z 2 
Di, se tri, tetra, penta-merous, , three, four, 
or five parts in cach sot. 
%. 
Sessile, without peduncle; pedunculate, = Y 
DEVIATIONS FROM THE NORMAL OR PATTERN FLOWER 
ARISE FROM 
with peduncle. 
Augmentation, increase of floral circles (Water Lily). 
Chérisis, increase of organs by division. The Bleeding-heart 
shows the collateral chorisis of stamens, and the Catchfly 
= shows the ¢ransverse chorisis of corolla. 
Anteposition, parts opposite instead of alternate (Grape). 
Cohesion, FF union of parts of the same set (corolla of 
Morning-glory). 
Adnation, wnion of different sets. In the Cherry the stamens 
and corolla are inserted upon the calyx. 
Irregularity, parts of the same set unequally developed 
(Violet, Pea). 
Suppression, non-development of some parts. In the mints 
some of the stamens are suppressed or wanting. 
CALYX. 
Sepats, < the divisions of the calyx. 
Tube, the united portion of a gamosepalous calyx. 
Parts. 
Teeth or lobes, the distinct or divided portions of a gamo- 
sepalous calyx. 
Throat, the orifice or summit of the tube. 
Pappus, | in Composite, the calyx border consisting of 
scales, teeth, bristles, or slender hairs. 
Cohesion, — Gamosepalous or Monosepalous, sepals 
partially or wholly grown together. 
Truncate, without lobes, 
Teothed, | lobes small. 
Lobed, WY parted about one fourth. 
Cups NYY parted about one half. 
Parted, Ye separated nearly to the base. 
Polysepalous, De separated to the base. 
Adnation. — Inferior, Ly calyx free from ovary. 
Se 
Superior, aE calyx adherent to the ovary. 
Half-inferior, calyx adherent to the ovary half-way. 
Form. — See under COROLLA. 
ZEstivation. — See under CoROLLA. 
COROLLA. 
Parts. — Petals, SQ the divisions of the corolla, 
Lamina, the expanded am; the petal. 
Clau', E \ the stem portion of the petal. 
SpurR 5, the hollow portion of certain corollas. 
* ( 
Crown, a small projection from certain petals 
(Catchfly). 
Cohesion. — Gamofetalous or Monopetalous, Vv petals 
partially or wholly grown together. 
Truncate, Hf toothed, lobed, VW cleft, parted. 
Polypetalous Se) petals separate.
