supremo oriundi; flores erecti, parvi; calyx parum inflatus, c. n.o mm. 

 longus et 6.0 mm. diam., fere glaber, circiter ad ^ longitudinis 5-lobatus, 

 lobis ovatis, acutis, striis inter se fere aequalibus, baud connatis exaratus ; 

 corolla exserta, rosea (?); petala unguibus e basi angusta sursum sensim 

 valde ampliata, auriculis distinctis, rotundatis, appendicibus parvis, angustis, 

 longioribus quam brevioribus, plerumque apice emarginatis, laminis c. 14.0 

 mm. longis, ultra medium bilobatis, lobis linearibus, divergentibus, apice 

 rotundatis ; styli 5 ; stamina paullo exserta ; capsula sessilis. 



South Patagonia in dry steppe at Richmond farm, not far from Sta. Cruz 

 Emporium ; collected in S. Patagonia also by the Princeton University 

 Expedition, but locality not indicated. 



Perennial ; rhizome upwards about 4 mm. thick, divided into few, short 

 branchlets covered with old, fragmentary leaves and bearing at top a dense 

 fascicle of filiform leaves about 4.5 mm. long and 0.5 mm. broad, often 

 subrecurved, glabrous or, at first, marginally ciliolate, when dry with 

 strongly recurved margins, the robust middle nerve very prominent under- 

 neath, callous at top, acute, sessile, abruptly passing into the broad and 

 short, membranaceous sheaths marginally ciliate ; scapes elongate, to 22 

 cm. tall, slender, below about 0.8 mm. thick, substriate, glabrous, trino- 

 dose with small, opposite, linear leaves, being marginally ciliate below and 

 broader and united at base; pedicels slender, 3-6 cm. long, upwards 

 glandulous puberulous, i -flowered, solitary or two or three emanating 

 from the uppermost node ; flowers erect, small ; calyx only somewhat 

 inflated, about 1 1 mm. long and 6 mm. wide, almost glabrous, lobed to 

 about one-third of its length with ovate, acute lobes ; petals with conspic- 

 uous, rotundate auricles and small, narrow appendices, being longer than 

 broad and usually emarginate, the blades about 14 mm. long, deeply 

 (more than to the middle) bilobed, the lobes being linear and rounded at 

 top ; styles 5 ; capsule sessile. 



A very well-marked species, differing from all other South American 

 species of the present genus in the narrowness of its leaves and the 

 smoothness of most of its parts.
