5F6887C5FFC7FFB3E881FD3EFABEB71A.taxon	diagnosis	Diagnosis: — Tripogon nicorae var. aristulata differs from T. nicorae var. nicorae in having narrow paleas 0.4 − 0.5 mm wide that are apically bilobed with two excurrent veins forming mucros 0.3 – 0.5 mm long. Caespitose perennials with fibrous remains of old sheaths. Culms (2.2 –) 3 – 5 cm tall. Sheaths striate, glabrous. Ligules 0.5 – 0.8 mm long, membranous, densely pilose at margins, the hairs up to 0.5 mm long. Leaf blades 15 – 40 × 0.3 – 0.5 mm, filiform, conduplicate, abaxially glabrous, with white and twisted long hairs on adaxial surface and two lateral tufts of long hairs near the ligule, margins scaberulous. Terminal raceme 0.8 – 2.4 cm long, straight, exserted, dark olivaceous to purplish. Rachis 0.5 – 0.6 mm wide, margins scaberulous. Spikelets 4 – 8 × 1.2 – 1.5 mm, 4 – 5 - flowered, subsessile, alternate on the rachis, the distal ones crowded and the basal ones distant from each other. Glumes 1 - veined, lanceolate, glabrous. Lower glume 2 – 2.5 mm long, apex mucronate, keels scabrous. Upper glume 2.6 – 3 mm long, apex obtuse. Florets imbricate. Lemmas 2.3 – 2.5 × 0.6 – 0.7 mm (not including awns), ovate, broadened at the middle third and narrow towards the apex, 3 - veined, glabrous, apex bilobed, midvein prolonged in a straight awn, the awn 1.2 – 2.9 mm long, lateral veins excurrent and mucronate, the mucros 0.4 – 0.6 mm long; callus pilose, the hairs 0.5 – 1 mm long; rachilla internodes 0.6 – 0.8 mm long, glabrous, scar joint narrowly elliptic. Paleas 2 – 2.5 × 0.4 – 0.5 mm, apex bilobed with two excurrent veins forming mucros 0.3 – 0.5 mm long. Lodicules 2, ca. 0.3 mm long, apex truncate. Stamens 3, anthers 0.4 – 0.5 mm long, purplish. Stigmas 2, plumose, purplish. Caryopsis 1 – 1.5 × 0.2 – 0.3 mm, subtriangular in transverse section, without ventral furrows, endosperm dry, hilum ellipsoid, embryo 1 / 3 the length of the caryopsis.	en	Gutiérrez, Harol, Castañeda, Roxana, Gonzales, Teresa, Mendez, Alejandrina Sotelo-, Peterson, Paul M.

5F6887C5FFC7FFB3E881FD3EFABEB71A.taxon	biology_ecology	Ecology and distribution: — This variety has been collected at high elevations in the mountains of Peru in the Department of Huancavelica and Moquegua (Fig. 3), on moderate to high rocky slopes, at 2472 – 3600 m, with seasonal vegetation.	en	Gutiérrez, Harol, Castañeda, Roxana, Gonzales, Teresa, Mendez, Alejandrina Sotelo-, Peterson, Paul M. (2021): Tripogon nicorae var. aristulata (Poaceae), a new variety from Peru. Phytotaxa 523 (1): 110-115, DOI: 10.11646/phytotaxa.523.1.7
5F6887C5FFC7FFB3E881FD3EFABEB71A.taxon	etymology	Etymology: — The epithet aristulata refers to the presence of two mucronate excurrent veins of the palea (Fig. 1 F). Taxonomical notes: — Tripogon nicorae var. aristulata can be separated from T. nicorae var. nicorae in having apically bilobed paleas with two excurrent veins that form mucros 0.3 – 0.5 mm long (Fig. 1 F; vs. apex 2 – toothed in T. nicorae var. nicorae), lemmas with lateral excurrent veins with mucros 0.4 – 0.6 mm long (Fig. 1 D – E; vs. 0.1 – 0.4 mm long), and keels of the lower glume scabrous (vs. keels smooth). The typical variety of this species occurs in Argentina, Bolivia, Chile, Ecuador, and Peru (Rúgolo & Vega 2004), whereas the new variety is only known from Peru (Fig. 3).
