0388D31CFFD2C67AFF2FFF6FE6F4E7C4.taxon	diagnosis	Diagnosis: — A diminutive species restricted to alkaline seepage areas in Tasmanian buttongrass moorland and most similar to the larger Isoetes drummondii, from which it differs most conspicuously by its strongly recurved leaves, disproportionately large ligules and congested, boldly ornamented regulate-cristate to columnar, slightly triangular megaspores and finely papillate microspores. Type: — AUSTRALIA: Tasmania, Maxwell Valley near Lancelot Hill, 42 ° 31 ’ S 145 ° 55 ’ E, in alkaline pan, 190 m elevation, 26 April 1985, S. J. Jarman (holotype HO 314939!; isotype DFB!

0388D31CFFD2C67AFF2FFF6FE6F4E7C4.taxon	description	Description: — PLANTS: short (leaf rosette above corm <6 cm tall), amphibious, herbaceous (Figure 1), arising from an approximately 0.75 − 1.00 cm wide, three-lobed corm (rhizomorph); LEAVES: spirally arranged, simple, dull blackish to gray-green with lighter bases, 1.0 − 2.3 mm wide at mid-point (dried), thin-walled, typically distinctly flattened and longitudinally folded adaxially in the lower half and terete upwardly (some terete throughout); alae extend approximately 20 % length of leaf; small central vascular bundle and narrow internal partitions create four atypically wide air chambers (Figure 4); SPORANGIA: oval, 3.0 × 2.4 mm, inserted into the basal inner side of the leaves, uniformly dark tan to brown; surface unmarked; fenestra complete (no velum coverage) (Figure 5); LIGULE: narrowly long-triangular with obtuse to acute summit, 60 – 80 % length of the sporangium (Figure 5); MEGASPORES: globose body, averaging 660 µm in diameter; congested ornamentation of distinct, thick walled, rugulate-cristate muri (walls) and / or tall, narrow, columnar muri (echinate-like appearance); low papillae evident on distal side of some otherwise smooth-walled, thin, alate equatorial ridges; slightly triangular megaspore shape results from subtle to prominent swellings (‘ knobs’) at the intersections of the equatorial ridge with the suture ridges (Figures 6 A− 6 D); MICROSPORES: plump, blunt-ended, with obscure to absent dorsal ridge; averaging 35.6 µm long; densely fine-papillate perispore ornamentation (Figures 6 E- 6 F); white to light tan en masse.	en	Brunton, Daniel F., Garrett, Michael, Sokoloff, Paul C., Kantvilas, Gintaras (2021): Description, distribution and ecology of endemic Tasmanian quillwort, Isoetes jarmaniae, sp. nov.

0388D31CFFD2C67AFF2FFF6FE6F4E7C4.taxon	distribution	Distribution and Habitat: — In coarse, peaty quartzite / silica sand substrate in periodically inundated (flowing) seepage areas over limestone bedrock, with sparse associated vegetation; found only in southwestern Tasmania, Australia. Chromosome Number: — Inferred diploid (2 n = 2 x = 22) by spore size conformity with cytologically confirmed diploid Tasmanian taxa: I. drummondii, I. elatior and I. gunnii (Marsden 1979, D. M. Britton pers. comm.).	en	Brunton, Daniel F., Garrett, Michael, Sokoloff, Paul C., Kantvilas, Gintaras (2021): Description, distribution and ecology of endemic Tasmanian quillwort, Isoetes jarmaniae, sp. nov.
