Description

Fruits: Pistil(s) compound; 1; 1-pistillate; with carpels united. Fruit anthocarpanthocarp:
simple or compound and including some tissue of non-ovarian origin (accessory tissue)
, or pericarpium; simple; nuculanium; simple; cypselacypsela:
dry, indehiscent, unilocular fruit with a single seed not adnate to the pericarp, similar to an achene but developed from an inferior ovary. Fruit type of Asteraceae.
, or diclesium; without persistent central column; crowned by plumoseplumose:
(of a hair or bristle) feather-like
calyxcalyx:
the outer whorl of the perianth; all the sepals of a flower
; with styles(s); at apexapex:

; within accessory organ(s), or not within accessory organ(s); within calyxcalyx:
the outer whorl of the perianth; all the sepals of a flower
; connate; persistent; hard calyxcalyx:
the outer whorl of the perianth; all the sepals of a flower
, or soft calyxcalyx:
the outer whorl of the perianth; all the sepals of a flower
; 1-seeded; 1-seeded; with 3-carpellate (but 2 are reduced & empty); with carpels united; with carpels remaining united at maturity; with carpels not radiating at maturity; with carpels remaining connected at stylestyle:

(with hairs); hairs not glandularglandular:
surface relief—covered with small, raised secretory glands, regular or irregularly shaped, translucent or opaque, and maybe distinctly colored
; without armature; smooth, or not smooth; without wing(s), or with wing(s); 1-winged; with wing(s) laterallateral:
(of embryo) embryo lies along the side of the seed, generally towards one end; of, at, or from the side; in grasses, can refer to the sides adjacent to the dorsal and ventral sides
; without apicalapical:
at or pertaining to the end of the seed or fruit distal from its point of attachment (i.e., base)
respiratory hole. Endocarpendocarp:
the inner layer of the pericarp, if divided into layers
present; not separating from exocarpexocarp:
outer layer of fruit wall or pericarp, if divided into layers; note here used synonymously with epicarp
; thin and hard; not splitting into 1-seeded pyrenes; without operculumoperculum:
a dehiscent cap (or lid) of a seed or fruit that opens during germination or dehiscence
; without secretory cavities; without longitudinallongitudinal:
of or relating to length or the lengthwise dimension
ridges. Funiculusfuniculus:
(alt. funicle) stalk connecting the ovule (later seed) to the ovary (later fruit) placenta

bristles or spines with curved or backwards pointing tips, or with secondary bristles along their length
(retinacula); not persisting in fruit after seed shed.

Seeds: Arilaril:
(broad sense) appendicular structure that wholly or partly envelops a seed and is produced from or a modification of the funicle, raphe, or outer integument; usually fleshy or pulpy, sometimes spongy or tufted-capillate, often brightly colored
absent. Seed not bowl shaped; not nutlike; without winglike beakbeak:
a usually firm, terminal appendage, sometimes tapered
; without caudatecaudate:

seed coat
present; without markedly different marginalmarginal:
at, on, or close to the margin or border
tissue; without fleshy or leatheryleathery:
