germination 2 |
|
CHARACTER |
|
The process wherein the contents of a spore begin active growth, exiting the confines of the spore wall via a pore or crack and giving rise to a gametophyte. |
present |
|
presence |
|
Occurring within the context in point. |
gibbous |
|
solid shape |
|
Bulging unilaterally near the base. |
prickle |
|
STRUCTURE |
|
Any unvascularized spine-like enation originating in the epidermis, cortex, or mesophyll of any shoot part. See also spine, thorn. |
chasmogamous |
|
reproduction |
flower |
Having the perianth open at anthesis, allowing deposit of pollen from other flowers (physiological receptivity aside). |
cotyloid |
|
architecture |
flower |
Having general adnation among the different sets of floral structures, thus having the ovary inferior and/or having a floral tube. |
cormose |
|
architecture |
plant |
Growing from corms. |
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. |
basiramous |
|
architecture |
axis |
Branching at or near the base. See also basicauliramous. |
seedling |
|
PLANT |
|
A plant in the first stages of its growth following emergence from the seed. |
isodiametric |
|
architecture |
|
Of approximately constant breadth in all median planes. |
androecial tube |
|
STRUCTURE |
|
The tubular portion of an androecium in which the component structures have fused with one another laterally over part or all their lengths. |
adnate |
|
fusion |
dissimilar structure(s) |
Intimately fused with or to one or more other dissimilar structures, the connection(s) with strong histological continuity. See also connate. |
stilt-rooted |
|
architecture |
plant |
Bearing and partly supported by stilt roots. |
staminal |
|
insertion |
|
Upon or otherwise directly associated with the stamens. |
cyme |
|
nominative |
inflorescence |
Determinate and constituting a compound dichasium or monochasium, the flowers maturing from the center outward (i.e., the distal or inner flowers maturing first); often more or less flat-topped. See also cymule, dichasium, helicoid cyme, monochasium, rhipidium, scorpioid cyme. |
strobiloid |
|
architecture |
flower |
Characterized by a general lack of adnation among the different sets of basic floral structures, any significant degree of fusion limited to connation within sets, thus with ovary(ies) superior and lacking a floral tube. |
synangium pl. synangia |
|
STRUCTURE |
|
A compound sporangium; an aggregation of coherent sporangia, the whole multilocular. |
derivation |
|
CHARACTER |
|
Ontogenetic origin. |
ochrea |
|
STRUCTURE |
|
See ocrea. |
supervolute |
|
vernation |
|
Each with one side rolled adaxially inward from the margin and enveloped by the abaxially rolled opposite side. |
duration |
|
CHARACTER |
|
Extent of lifetime, or persistence and physical state after maturation. |
obdiplostemonous |
|
architecture |
flower, androecium |
Having the stamens dicyclic, the proximal whorl with members directly above the petals, the distal whorl with members directly above the sepals. See also diplostemonous. |
thyrsate |
|
architecture |
inflorescence |
Comprising one or more thyrses. |
palmatifid |
|
solid shape |
|
Palmately lobate; having three or more lobes whose longitudinal axes radiate from a common point. |
