The species is known only from the type locality, at 1,400-1,600 metres elevation on the steep limestone ramparts of
Cerro Anguciana. Plants that were
epilithic had flattened leaves and spikes against the rock. Short, thick, subcormose stems measuring 0.2–0.8 x 0.15-0.25 centimetres. In the basal rosette, leaves appear to alternate.
Petioles are 0.3-1.9 centimetres long and spreading-
hirsute, with
uniseriate hairs. The blade of a leaf are 0.5-1.8 x 0.5-1.8 centimetres; broadly
ovate to suborbicular or subreniform; impeltate or hardly rounded to subtruncate; broadly rounded to moderately acute apically;
palmate: 3-5 nerved; appressed-hirsute on both sides (more sparsely so above);
pellucid-gland dotted at least above. single, basal inflorescences.
Peduncles are purbes as petioles, measuring 1.3–4.1 centimetres. The An unbranched, indeterminate inflorescence: beakless, elliptical to
wikt:subglobose, constricted to substipitate base, 2.7–7 centimetres x 0.3–0.4 millimetres;
stigma apical. The plants in this species bear a resemblance to miniature variants of
P. saintpauliella, from which they differ in having proportionately longer peduncles and highly pubescent inflorescences
rachises, in addition to their generally reduced size. This species is similar to some specimens of
P. tuerckheimii (including
P. hispidorhachis), a small
calciphile that also occurs in the same area.
P. tuerckheimii, however, has more elongate, peltate, non-cordate leaf blades with usually seven primary basal veins instead of five. ==Taxonomy and naming==
