Puna bonnieae Flower Light Pink , 4 cm in diameter
by D. J. Ferguson, S. Hogan and Bonnie Brunkow in
the early 1990
Description: This is a small
opuntioid that looks like a small
fruit and the
seeds clearly show its autonomous nature. During the dry season
they are hidden in the ground. It forms slowly small cushion up to
15 cm in diameter.
Stem: Small usually
globular, obconical to slightly elongated up to 2.5 cm tall and
in diameter, they are broadly attached basally and do not detach
easily from the mother plants. It is possibly an
adaptation to high
altitudes. They are dull blue-green but turns to dirty grey as
Tubercles: low, bordered with grooves and slightly depressed in
the centre in correspondence of the areole.
Areoles: Up to 30 per segment, closely set, with glochids and
spines only in the upper part of the stem.
Central spines: Absent.
Radial spines: 9 to 20. Pinkish, orangish, reddish to darker
brown in the young stems, they turn to a whitish grey colour with
age. They are very short, flattened and radiating and slightly bent
over the stem.
Roots: It has a large turnip, branched,
storage root (The roots of Tephrocactus are fibrous)
Flower: Flower Light Pink or Pinkish, 3-4
cm in diameter, arising from
buds with white
felt. The pericarp is naked or has only few areoles with some
bristle-like spines up to 3 mm long. This feature is typical for
Punas (While the pericarpus of Theprocactus has numerous areoles)
Fruit: The fruit is obovoid, top shaped,
about 1-1,5 cm long almost
naked and free of areoles. It is thin walled, fleshy becoming
dry at maturity.
