bud |
|
STRUCTURE |
|
A rudimentary, unexpanded stem, stem branch, inflorescence, inflorescence branch, or flower, or a combination thereof, in a resting state; enveloped or not by subtending protective scales. |
ribbed 2 |
|
solid shape |
|
Having two or more prominent, elongate, relatively narrow, essentially parallel protrusions that extend over all or most of its length or circumference. |
ridge |
|
FEATURE |
|
A very narrow, elongate, relatively low protrusion; esp. on fruits in Apiaceae (Umbelliferae). |
homogamous 2 |
|
reproduction |
plant, inflorescence |
Having flowers that do not differ in sexual constitution. |
internode |
|
STRUCTURE |
|
Any portion of a stem between two successive nodes. |
indusium pl. indusia |
|
STRUCTURE |
|
A protective membrane that is an outgrowth from the epidermis and covers a sorus during its maturation; in Polypodiophyta. |
laevigate 1 |
|
relief |
|
Very smooth. |
semicircular |
|
arrangement |
bundle scars |
Forming an incomplete circle, like the letter C. |
solitary 1 |
|
arrangement |
|
Disposed singly, each remote from any others. |
simple-craspedodromous |
|
venation |
|
Having a midvein that branches to either side along the length of the lamina, the secondary veins and their branches all running toward and terminating at the margin. |
cell 1 |
|
STRUCTURE |
|
Any of the basic structural/functional units that collectively or individually make up the various tissues of a plant; comprising, at least while physiologically active, a nucleus with included genetic material (chromosomes), a surrounding cytoplasm with included organelles (e.g., ribosomes, mitochondria, plastids), an enclosing membrane, and an exterior cellulosic wall. |
spinulose |
|
architecture |
|
Finely spinose. |
anther |
|
STRUCTURE |
|
The fertile, loculate, pollen-bearing portion of a stamen, containing one, two, or four thecae (pollen sacs), when that portion is differentiated from and borne at the summit of a narrower supporting stalk (filament), or when such differentiation is deemed to have occurred in the evolutionary past with subsequent reduction of the filament (the anther then sessile and constituting the entirety of the stamen). |
cleistogamous |
|
reproduction |
flower |
Having the perianth remaining closed through anthesis, preventing deposit of pollen from other flowers, thus only self-pollination possible. |
…ciliate |
|
architecture |
|
Bearing the number of cilia indicated by the prefix. |
deciduous 2 |
|
habit |
plant |
Perennial and having all leaves separating and falling away during a particular portion of the yearly cycle, especially the autumn or the dry season, between growing seasons. Semantically, this term is properly applied only to the entity that falls, not to the structure that it separates and falls from; in traditional usage, though, the term has been applied to trees and other perennial plants that shed all their leaves at some time during the yearly cycle. |
oblate |
|
solid shape |
|
Symmetrically elongate and broader than long perpendicular to the developmental or polar axis. |
node |
|
STRUCTURE |
|
One of the evident sectors of a stem that occur sequentially along its length and from which leaves (megaphylls) and lateral branches arise exogenously. The anatomy of nodes differs from, but is not abruptly distinct longitudinally from, that of the intervening sectors (internodes), with which it is smoothly confluent and from which is distinguished by the lateral transit and egress of vascular traces interconnecting the stem and the leaves and branches that it bears. |
aquatic |
|
habit |
plant |
Growing in water. |
disc 2 var. disk |
|
STRUCTURE |
|
Collectively, the disc florets of a capitulum (head), or the surface presented by them. |
synstemonous |
|
architecture |
flower, androecium |
Having two or more stamens, some or all of them connate. |
endophytic |
|
habit |
|
Growing within some portion of another, unrelated, living plant. |
axile |
|
placentation |
|
Upon the central axis of a compound, plurilocular ovary. |
corolla tube 1 |
|
STRUCTURE |
|
A relatively narrow, fully connate portion of a sympetalous (gamopetalous) corolla proximal to a broader portion (limb) that comprises the distinct or connate distal portions of the petals; except in bisexual or staminate disc florets of Asteraceae (Compositae). |
trichotomocolpate |
|
architecture |
pollen grain |
Having a triradiate surficial groove (colpus). |
