caespitose : tufted.
calyx : the sepals as a whole.
campanulate : bell shaped.
capitula : heads of sessile flowers, surrounded
by an involcure of bracts.
corolla : the petals as a whole.
cuneate : see Leaf Morphology Diag.

ellipsoid : of a solid object, elliptic in
longditudinal section.
epigunous : of the whole flower or the perianth
& stamens of a flower with an inferior ovary.
filiform : thread like.
glabrous : without hairs.
gynoecium : female parts of a flower.
indehiscent : not opening to release seeds.
infloresence : flowering branch, includes branch,
flowers, bracts.
involucre : bracts forming a >or< calyx like
structure round or just below the base of a
usually condensed inflorescence.
linear : See Leaf Morphology Diag.
lanceolate: See Leaf Morphology Diag.
mucronulate : having a small sharp point.
palmate : consiting of more than 3 leaflets arising from the same point, panicle : strictly a branched racemose
inflorescence.
papillose : small elongated projections.
pappus : downy or feathery appendage on achenes.
perennial : living for more than 2 years, flowering each year.
perigynous zone : the annular region between the insertion of the gynoecium and of the other
