Description
|
Plants with the habit of a miniature Iris, surrounded at the base with the matted fibers of past leaves, discoloring in drying; roots partly slender and fibrous and partly short and tuberous; leaves linear-ensiform, 9-15 cm. long, 0.1-0.2 cm. broad, erect, borne both basally and sparsely upon the stem; flowering stems 1.5-2.0 dm. tall, inconspicuously an- cipitous, usually simple and straight, infrequently branching and then somewhat flexuose; inflorescence simple, 2- to 6- flowered; spathe valves subequal, lanceolate, the outer 2.5- 4.0 cm. long; perianth broadly ampuliform, yellow veined with brown, 1.2-1.5 cm. long, glabrous; stamen filaments 0.4-0.6 cm. long, connate somewhat below the middle; capsules oblongoid, 1.0-1.3 cm. long, about 0.4 cm. broad; seeds subglobose, about 0.13 cm. in diameter, opaque, smooth or very inconspicuously foveolate, with a very deep micropylar pit.

Note
|
We have only Baker's description to support assignment of these plants to S. Mandoni, but the agreement is striking. It is unfortunate that Baker did not include descriptions and measurements of seeds in his descriptions of Sisyrinchia, for we have been very strongly impressed by their use as diagnostic criteria. The smooth seeds of our Panamanian plants, with, their deep micropylar pits, are quite unlike those of any other species known to us, and should be of considerable use in the final taxonomic disposition of the plants.
