Type
Type: South Africa, Zwellendam W George, Mundt s.n. (B, holo.)
Morphology General Habit
Perennial up to 35 cm high, with stolons up to 2 m long.
Morphology Stem
Rooting copiously at each node and ending in an inflorescence.

Culm trigonous, smooth, sometimes ± grooved, the non-bearing leaf part 3–29 cm long, 0.7–2.5(–5) mm wide

Note
Although this species is easily recognizable, it is also very variable. The habit can range from very delicate stolons, leaves and culms to more robust ones; the inflorescence can also vary between specimens, e.g. capitate or simple inflorescences, and the number and length of primary branches, or the size and in shape of the spikelets. Most specimens have ovoidlanceolate spikelets, but some have spikelets which are more obviously ovoid, with loosely arranged glumes and somewhat curved axis, or almost rounded spikelets, not flattened as most Pycreus species, with a low number of glumes which are vere densely compressed. " Pycreus mundtii is easy to recognize as it has leaves up the flowering culm, which separates it from almost all other species in the Flora area. Another good character for this species are the glumes having furrows on each side of the keel, a character which is shared with P. sanguinolentus Vahl. These two species can be easily separated based on habit. In the past, an number of varieties and separate species were described, based on some of these characters. In the FTEA region quite a large number of the specimens can be divided in three groups, according to previous varieties or species. However, quite a distinct number of specimens show characters shared by more than one group, or coincide with each other, and therefore are impossible to identify further than species level; I do believe that varieties can be recognized in this species to a certain level; this distinction will not work on all specimens.
