250 Standley — Tlie American Species of Fagonia. 



From all our other species this is distinguished by the glabrous ovaries 

 and the completely glabrous stems. Aside from these differences it is not 

 far removed from Fagonia calif ornica. 



12. Fagonia longipes .Standley, sp. now 



Stems very slender, glabrous, angled, about 30 cm. lung, abundantly 

 branched; petioles 4 to 10 mm. long, stout, glabrous; stipules stout, 1.5 

 to 2 mm. long, slightly reflexed; leaflets 3, glabrous, linear-oblong or 

 linear-lanceolate, the lateral ones oblique, :i to 10 mm. long, minutely 

 spinulose tipped; pedicels 10 to 12 mm. long, slender, glabrous or ob- 

 scurely scaberulous, deflexed in age; sepals lanceolate or oblong-lanceo- 

 late, acute or acuminate; petals 7 to 9 mm. long, rose purple; fruit 4 

 mm. high, sparingly and finely pubescent and slightly glandular, with a 

 beak 1.5 mm. long. 



Type in the XLS. National Herbarium, No. 14, 222, collected in Arizona 

 in 1876 by Dr. Edward Palmer. No other data are given on the sheet in 

 the National Herbarium but on one in the J. II. Redfield Herbarium in 

 the collection of the .Missouri Botanical Garden, the label gives the 

 locality as Bill Williams Fork, the date of collection as March II, and 

 the collector's number as 58. 



The plant is related to Fagonia californ.ica but may be distinguished at 

 a glance by the very long pedicels. The stems, too, are nearly glabrous, 

 the stipules shorter, and the whole plant more slender.
