The epithet of this new species is a reference to its compact leaf rosette due to the comparatively shorter and densely rosulate
leaves, which is a striking distinctive character of A.
The most common habit of herbs was rhizomatous (11 species), followed by rosulate
habit (7) (Tab.
As frequent species we can remark other shrubby halophytes such as Arthrocnemum macrostachyum, Suaeda vera or Halimione portulacoides; frequent rosulate
hemicriptophytes are Limonium angustebracteatum, Limonium caesium, Limonium cossonianum and Limonium eugeniae.
to sub-rosulate; capitulescences of few capitula Adenocaulon 16b.
1 mm wide at base, the basal ones 3-10 mm apart, antrorse (upper ones) to retrorse (basal ones) uncinate; fascicles 7 to 11 in number, polystichously arranged, suberect, sessile, globose-capitate, strobilate, densely rosulate
, 12-15 mm long (excluding the petals), 14-17 mm in diameter, 7 to 12-flowered; floral bracts broadly triangular-ovate, acuminate, slightly carinate toward the apex, equaling to slightly shorter than the sepals, but recurved and distinctly exposing them, green, nerved, inconspicuously and sparsely white-lepidote but soon glabrous, 10-13 x 8-10 mm, subdensely spinulose, spines irregularly curved, 0.5-1 mm long.
Leaves usually rosulate
or clustered at the median part of the stem; sessile to distinctly petiolate with petioles winged to wingless; blades linear, elliptic, obovate, deltoid to subrounded, palmately, pinnately, three- to five-veined, margin entire to partite, glabrous to pubescent on both surfaces or only beneath.
Structurally there is here -- compared to the other communities identified -- an evident increase of rosulate
Hemycryptophyte probably due to the presence of both rich soils and a fair quantity of light at ground level (Table 1).
Epiphyte, rarely saxicolous, rosulate
herbs, dioecious, flowering up to 1.5 m high.
Leaves 30 to 35 in number, rosulate
, densely arranged and forming a distinct rosette before anthesis and afterwards; sheaths inconspicuous; blades narrowly sublinear-triangular, 9-12 cm long, 0.6-0.7 cm wide at base, ca.
; pseudopetiolate, blades lanceolate, elliptical to obovate, pinnately veined, margin denticulate to lyrate, glabrous to pubescent.
These five species comprise the complete range of growth forms known for the genus, i.e., subshrubs, cushionforming herbs, acaulescent, rosulate
herbs and vines.
and multiradiate trichomes were only observed in section Lobatae (red oaks) (Hardin, 1979a, b).
