Description

Plantae habitu Iridem gracilem vel Orthrosanthitm simulantes, fibris foliorum vetustorum basi parce persistentibus, post exsiccationem discoloratae. Radices elongatae paulo incrassatae conspicue pubescentes. Folia lineari-ensiformia, radicalia 30-40 cm. longa 0.5-1.0 cm. lata, caulinia brevioria. Caules florigeri 4-5 dm. alti inconspicue alati repetite ramosi haud flexuosi. Inflorescentia simplex 1-3-flora; spathae valvae paulo inaequales ovato-lanceolatae exteriores 2.5-4.0 cm. longae. Perianthium amplissimum luteum brunneo-nervatum 1.6-1.8 cm. longum glabrum. Staminum filamenta 0.6-0.7 cm. longa sub medio connata. Capsulae ovoideae basi apiceque angustatae ca. 1.5 cm. longae 0.9 cm. crassae; semina sub- globosa ca. 0.2 cm. diametralis conspicue reticulato-foveolata. Plants with the habit of an Iris or an Orthrosanthus, surrounded at the base with persistent fibers of past leaves, greatly discolored in drying; roots elongate and somewhat fleshy, the persistent hairs very conspicuous and matted; leaves linear-ensiform, the basal 30-40 cm. long, 0.5-1.0 cm. broad, the cauline pro- gressively shorter to the spathes; flowering stems 4-5 dm. tall, inconspicuously alate, branching repeatedly, not flexuose; inflorescence simple, 1- to 3-flowered; spathe valves slightly unequal, ovate-lanceolate, the outer 2.5-4.0 cm. long; perianth very broadly ampuliform, yellow veined with brown, 1.6-1.8 cm. long, glabrous; stamen filaments 0.6-0.7 cm. long, connate somewhat below the middle; capsules ovoid, tapered at both base and apex, about 1.5 cm. long and 0.9 cm. thick; seeds subglobose, about 0.2 cm. in diameter, conspicuously reticulate- foveolate.

Note
|
Amongst species known to us, S. chiricanum most resembles S. arizonicum, at least as to general habit and roots. The capsules of the latter, however, are bluntly oblongoid, and its seeds are even larger than those of S. chiricanum. Both species are striking in their habit of bearing one or more leaves upon the branches of the flowering stems. The stems of S. arizonicum are more broadly winged than those of S. chiricanum.
