BOTAITY. 
long ; seeds 6-8, over i" long, transversely rugose and pitted. — In the lower 
Humboldt and Reese River Valleys, Nevada; 4-5,000 feet altitude; May- 
July. It is also tlie Eutoca aretioides of Ives' Report, collected on the Flax 
River in Northern Arizona. Apparently reseml}ling MUtitzia luiea^ DC, 
found by Tolmie in Eastern Oregon or Southern Idaho, which differs, accord- 
ing to the description, in being scabrous-pubescent, the linear sepals 3" long, 
the corolla-tube pilose externally, the disk none, (or more probably narrow,) 
and the ovary also pilose. (886.) 
Teicaedia^ Watsoni, Torr. Stems several from a perennial caudex, 
6-8' high, simple, pilose with white webby hairs ; leaves lanceolate, acutish, 
pubescent, the radical ones 1-2' long, attenuate into a long petiole, the cau- 
line in length, sessile or short-petioled ; racemes axillary and terminal, 
6-10-flowered ; pedicels slender, mostly nodding; calyx glabrous, from 2" 
becoming 1' long, the outer three sepals deeply cordate, subchartaceous, 
very strongly veined, the inner linear ones a little shorter ; corolla purplish, 
3" deep, the lobes rounded, spreading ; style twice longer than the ovary ; 
capsule 3" long ; seeds 1" in length, slightly roughened.— A plant of solitary 
habit and rare. The mature capsule in every case examined w^as compressed 
parallel with the placenta, which in some cases remained united a consider- 
able part of their length. The young ovary rather indicates compression 
in the other direction. Found on foot-hills of Truckee Pass and the Trinity 
Mountains, Western Nevada ; 4-4,500 feet altitude ; May. Plate XXIV.
