hastatus,-a,-um (adj.A): ‘Halbert-headed. Abruptly enlarged at the base into two diverging lobes, like the head of a halbert” (Lindley); 'armed with a spear,' hastate, i.e. with equal more or less triangular basal lobes directed outwards, abruptly broadened and auriculate at the base, shaped like an arrow but with the basal lobes pointing outward at wide angles; 'halberd-head-shaped;' cf. sagittatus,-a,-um (adj.A);

- antherae biloculares basifixae hastato-oblongae truncatae (F. Mueller), the anthers bilocular, fixed at the base, hastate-oblong, truncate.

- foliis inferioribus subdeltoideis laciniatis, ceteris hastato-trilobis, lobis posticis angulato-dentatis divaricatis (F. Mueller), with the lower leaves somewhat deltoid, laciniate, the rest hastate-trilobed, with the postical lobes angulate-dentate, wide-spreading.

- foliis caulinis basi auriculis acutis hastato-amplexicaulibus (F. Mueller), with cauline leaves at the base with acute auricles hastate-stem-clasping.

- S. subhastatum; foliis caulinis lanceolatis basi auriculis acutis hastatis (DeCandolle), with cauline leaves lanceolate. at the base with the auricles acute, hastate.

- foliis triangulari-cordatis hastatisve (DeCandolle), with the leaves triangular-cordate or hastate.

- foliis inferioribus triangulo-hastatis crenatis (DeCandolle, with the lower leaves triangular-hastate, crenate.

- [Banisteria sagittata] foliis hastato-sagittatis (DeCandolle), with the leaves hastate-sagittate.

angulato-hastatus,-a,-um (adj.A): “hastate, with the lower lobes connected with the stalk by a wedge-shaped process or part” (Lindley).

cordato-hastatus,-a,-um (adj.A): “between cordate, q.v., and hastate” (Lindley).

lanceolate-hastate, “a hastate leaf whose principal lobe is lanceolate” (Lindley): lanceolato-hastatus,-a,-um (adj.A).

NOTE: a halberd “a weapon used esp. in the 15th and 16th centuries that consists typically of a battle-ax and pike mounted on a handle about six feet long” (WIII).

NOTE: hastate seems to refer to cordate or auriculate basal lobes that are acute, not rounded, and with a leaf that is overall sagittate or deltoid-triangular.

 

A work in progress, presently with preliminary A through R, and S, and with S (in part) through Z essentially completed.
