Micropropagation of Cereus peruvianus Mill (Cactaceae) by areole
KEY TO THE NORTH AMERICAN HAIRWORM SPECIES A Cuticle smooth, lacking areoles
or B with flat, smooth areoles
; male tail bilobed (as in Figs.
Cactus branches bear many areoles
(spine-bearing pads) that can produce one or more flowers per night.
sclereids of the areole
or belong to the sarcotesta.
These specialized types include modifications of the whole shoot apex, cephalium, or merely of the flower-bearing areoles
(Mauseth & Kiesling, 1997).
The fruits are globose or subglobose, sometimes oblong, fleshy, red to green, with persistent spiny areoles
One characteristic of the Oligocene intrusive bodies is the creation of alteration areoles
in Eocene volcaniclastics, and their hydrothermal phases have been generally accompanied by the formation of elements such as epithermal gold, copper, lead, zinc and kaolin.
1] deeply convex distad of claval apex, almost reaching M, hence slightly detached; with a callus in costal cell, 6 apical areoles
distad of stigma, apical part behind apex of clavus folding down and covering apex of abdomen.
However, Bowers (1996) suggests that the cladodes produced during the previous year leads to a higher number of unused areoles
that translated into a higher number of new cladodes and flowers that was not necessarily coupled with rainfall.
having distinctive more or less quadrangular areoles
filled with branching veinlets present between the secondary veins.
Hemelytra: Subparallel, impunctate, shiny, with scattered scalelike setae, intermixed with semi-erect, simple setae; basal width of cuneus about three fourths the length; membrane entire with two areoles
, one large, one small and narrow.
Aspicilia contorta is easily recognised by the scattered areoles
, convex, grey and more or less pruinose, and by the sunken apothecia.
The dorsal plain is smooth, with a few areoles
only towards the lateral margin, but without any rudiments of keels.
Her cetacean breasts narrowed to the areoles
like the snout of a humpback.
violaceus are polygonal structures of the cuticle called areoles
, which are surrounded by fine cuticular bristles.
