|
sinus pl. sinus, sinuses |
|
FEATURE |
|
The space, indentation, or invagination (or, for some descriptive purposes, the outline thereof) between and delimiting any two consecutive or adjacent lobes or teeth of a structure. |

|
architecture |
flower, androecium |
Having stamens unequal in size and/or shape. |
|
monolete |
|
architecture |
spore |
Having a single linear tetrad scar (surficial ridge or angle resulting from ontogenetic coherence with others produced from the same spore mother cell). |
|
capitulescence |
|
architecture |
|
Mode or progressive pattern of bearing capitula (heads); most appropriately described using adjectival terms; esp. in Asteraceae (Compositae). |
|
pilose |
|
pubescence |
|
Bearing relatively sparse, soft, slender, more or less erect capillate trichomes. See also pilosulous. |
|
neck (floral tube) |
|
STRUCTURE |
|
The solid, usually constricted portion of a floral tube sometimes present between casing and collar when those are both present. |
|
cauline |
|
insertion |
|
Upon, arising from, or otherwise directly associated with the stem. |

|
extravaginal |
|
insertion |
|
Distal to or outside the leaf sheath. |
|
arrangement |
|
CHARACTER |
|
Disposition of equivalent structures with respect to one another (positions/insertions and/or orientations, regarded collectively) within some explicit or implicit standard context. Overlaps conceptually with habit, insertion, orientation, position, and shape. |
|
haplomorphic |
|
architecture |
flower |
Having the members of each set of basic floral structures numerous and spirally arranged, the flower hemispheric to conoidal overall. |
|
thallus 2 pl. thalli |
|
STRUCTURE |
|
The main body of a gametophyte, bearing rhizoids, gametangia (antheridia and/or archegonia), and/or gemmae cups; usually thin and more or less planate, inconspicuous, and growing appressed to or beneath the substrate surface; in Psilotophyta, Lycopodiophyta, Equisetophyta, Polypodiophyta. See also prothallus. |
|
leptosporangiate |
|
reproduction |
|
Having relatively small sporangia each of which develops from a single initial cell that, by periclinal division, gives rise to an outer and an inner cell, the former then giving rise to the entire sporangium, including contents and sporangiophore, the latter contributing nothing to it; in some Polypodiophyta. |
|
herbaceous 2 |
|
texture |
|
Composed entirely of relatively soft, non-woody (unlignified) tissues derived from primary growth. |
