Discussion:
The available material of the new species is not entirely satisfactory, but one good mature flower has been dissected. Because of its free filaments, the species would be sought among those numbered 10 to 18 in my key of 1932 (Contr. U. S. Nat. Herb. 28: 411), but its relationship is certainly with T. anomala A. C. Sm., based on an Andre collection without detailed locality. From this, T. jorgensenii differs in its leaf-blades with subcordate bases and its subsessile flowers with free filaments; T. anomala has the indument of the flowers much denser, covering even the calyx-limb, which in the new species is essentially glabrous.
