Ray Clark ... "I bought this one at a BSSA sale in 2012 ex Bill T, so I would guess maybe ex UD which would narrow it down to four options. Either way Iím happy."

Desc from S&D p812
Plants often pulvinate, flowering to 13 cm high; stem short but usually distinct, simple or few-branched; roots present.
Leaves densely polystichous, often secund-curved, to 13 cm long but the lower ones much reduced;
Sheaths triangular, merging imperceptibly into the blades, thin, at least the lower half glabrous and lustrous;
Blades erect or suberect, very narrowly triangular or linear, abruptly acute, pungent, rigid, channeled above, obtusely carinate beneath, angular-subulate, 3-6 mm wide, covered with closely appressed cinereous scales.
Scape from practically none to 6 cm long, exceeded by the leaves, erect or ascending, glabrous;
Scape-bracts imbricate and concealing the scape, lanceolate, acuminate, stramineous, chartaceous, strongly nerved, glabrous.
Inflorescence always simple, broadly lanceolate or oblanceolate, strongly complanate, to 45 mm long and 15 mm wide, 4-7-flowered, glabrous throughout;
rhachis nearly straight, strongly 4-angled.
Floral bracts imbricate but narrow and exposing the rhachis, lanceolate, acuminate, to 25 mm long, much exceeding the sepals, subcoriaceous, even or somewhat nerved, ecarinate, red, sublustrous;
Sepals narrowly lance-triangular , acuminate, 12-18 mm long, free, subequal, the posterior carinate;
Petals narrow with scarcely distinct suberect to spreading blades, ca 30 mm long, obtuse, entire, bright rose-red;
Stamens ca 20 mm long, shorter than the pistil, filaments thickened and transversely plicate, anthers linear, 5 mm long;
Capsule cylindric, beaked, 20 mm long.

Comments from L. B. Smith, Proc. Am. Acad. (Contr. Gray Herb. 106) 70: 172. 1935.
Baker, Mez, Castellanos and Harms have all considered this species as identical with T. unca Griseb., but none of them cite the type of T. unca and I have not been able to locate it as yet either. However, there is ample evidence in the original description to prove that true T. unca is nearly related to if not identical with T. pulchella Hook.
Venturi 1315 from Barranca Colorado, Tucuman, combines the characters of T. argentina and of T. ixioides; which have both been collected from that locality. The hybridizing of T. argentina with a species of Anoplophytum and its possession of plicate filaments make it seem logical to include it in that section. Such action means that Anoplophytum, like Allardtia and Platystachys, must include both simple distichous and simple polystichous types of inflorescence and must be characterized by the form of its filaments.
Comments from R Ehlers 2/1996
T. argentina has been found in Bolivia. I have slides from Vieweg/Balfanz for Oct. 1994 which they made between Tarija and Navarez 2000m. and I have plants in our collection collected by Haugg from 2-3 different locations. Lotte Hromradnik told me she found it before in Bolivia and always between1500 & 2000m. all these plants look like Argentinian plants, never like T. hasei. Also T. hasei grows more than 1000m higher.
