Splitting transversely through the exterior wall about its entire circumference, the resulting upper cap-like portion falling away. |
|
peduncle |
<stalk, stipe (broad sense, not recommended) |
STRUCTURE |
|
The common stalk, when present, of a compound inflorescence or first-order subunit thereof, or of a solitary flower that is deemed to represent an evolutionarily reduced compound inflorescence. |
|
powdery |
= granuliferous, pulverulent |
coating |
|
Covered with a more or less even deposit of fine, dry particles. See also dusty (lentiginose, lentiginous), which is not clearly distinct in its application. |

|
STRUCTURE |
|
Collectively, the disc florets of a capitulum (head), or the surface presented by them. |
|
eroded |
= erose |
relief |
|
Having rough, very irregular depressions throughout. |
|
scutelliform |
= platter-shaped, scutellate |
solid shape |
|
Relatively thin with opposite broad oval faces, shallowly concave-convex; like a serving platter. See also scutate (buckler-shaped, scutiform), which is not clearly distinct in its application. |
|
forked |
= furcate; > bifurcate |
apex |
|

|
theca pl. thecae |
= pollen sac |
STRUCTURE |
|
Any of the one, two or four ontogenetically distinct, pollen-producing sectors (microsporangia) of an anther. In some taxa the walls between pairs of adjacent thecae break down as an anther approaches maturity, the mature anther thus ultimately containing half as many locules as thecae. |
|

= pungent |
odor |
|
Sharp or astringent. |
|
archegonium pl. archegonia |
|
STRUCTURE |
|
A female gametangium; a multicellular fertile organ of a mature gametophyte within which female gametes (eggs, ova) are produced and fertilized; having a broad, bulbous base and a narrower distal neck. Technically present but highly reduced and of no descriptive significance in Magnoliophyta. |
|
loose 2 |
|
texture |
|

|
papillar(y) |
= papilliform |
solid shape |
|
