25-3 mm apart, bearing closely spaced verticils that overlap slightly in spread-out preservation.
DESCRIPTION: Ultimate axes apparently smooth, about 1 mm wide, with internodes 25 mm apart, bearing overlapping verticils with 14-16 isophyllous leaves, united at the base so as to form an annulus.
1), shows verticils composed of 14-16 isophyllous leaves, 7 to 14 mm long, with acute, mucronate apices.
Verticils on ultimate branches spaced at a little more than leaf length or slightly touching.
Matthew's variety was considered by Bell (1944) to fit the range of leaf length of Annularia latifolia; however, the verticils of the latter are anisophyllous and its leaves are widest in their upper third.
Verticils with 22-24 leaves, of unequal length, lying in the same plane as the axis and united at the base so as to form an annulus.
It is characterized by verticils with relatively long, spatulate, mucronate leaves.
Abbott (1958) accepted the connection between these "seeds" and the leaf verticils and synonymized Elias's Carpannularia americana with Annularia stellata.
Annularia jongmansii is characterized by anisophyllous verticils with lanceolate leaves showing a subrounded apex that includes a tiny mucron.
Annularia microphylla has verticils with lanceolate and sickle-shaped leaves of equal length and stiffer aspect.
Verticils of Annularia fertilis have isophyllous leaf whorls, with oblong, longer leaves, with a greater length/breadth ratio.
