4 x 1 mm, papillate
, sessile, not ribbed, style ca.
ovalifoliolata, the flowers are weakly protandrous, produce considerable per cent of sterile pollen and present the capitate, wet papillate
tri-lobed stigma above the stamens as in case of its allied species B.
hispanica possess a pileus different in form from all those species, because it is not acutely papillate
as in P.
Leaves pinnately lobed or dentate along margin; petal claw papillate
; median filaments united, papillate
Vesture of distal portions of peduncles of lateral spikes: smooth or very sparsely scabridulous (0); densely scabridulous (1); papillate
, with papillae dense and low (2); papillate
, with papillae sparse and tall (3).
colliculata is easily separated from the species that have seeds with smooth, muricate, muriculate, papillate
or colliculate with inflated cells surfaces.
According to the present study, the segregation of series Otopteri from Senecio seems justified by the concurrence of the following micromorphologi-cal characters: (1) style-arms that are apically convex or subconvex, papillate
or minutely papillate
, surrounded by a crown of hairs that are different in length; (2) members of the group usually with a cleft configuration of the stigmatic surface; and (3) auriculate anthers present in all of the group.
Rachises are scaly, papillate
, with occasional aerophores in the base of pinnae.
straight-straight margins, lack of accessory veins, deciduous papillate
apices, and clearly rosoid venation syndrome of nonjoining, connivent
0 in upper jaw, its center well behind midpoint of upper jaw; anterior nostrils tubular, elongate, about twice in eye, with small lappet extending from each side; posterior nostrils in upper lip, not visible externally, beginning before eye and ending beneath middle of pupil; upper lip papillate
, particularly between anterior and posterior nostrils; broad fleshy chevron dividing snout between anterior nostrils; dorsal fin origin on head, well in advance of gill opening, 1.
Distal genitalia (Figs 9C, 74, 75): Penis very long and slender, often sinuously folded in situ; its wall muscular, particularly towards base; internal lumen lined by papillate
Etymology: The name of the species "anulatus" refers to a ring that is found near the middle of each dorsal papilla that separates the smooth from the papillate
