(5, Iloqicin) or wanting. Ovary ovate : styles 2, free or united at 

 base. Fruit partially covered by the loosely appressed calyx ; pericarp 

 membranous. Seed lenticulai', with a crustaceous testa. — Herbaceous 

 annuals, erect and diffuse ; the minute solitary flowers very shortly 

 pedicelled, axillary and terminal upon the repeatedly dichotomous 

 nearly naked branches ; terminal flowers abortive and deciduous, leav- 

 ing the ultimate branchlets spinulose : leaves thin, alternate. 



1. T. ARISTATA, Moquin. Glabrous, 6 inches high; leaves entire, 

 linear to linear-lanceolate, 1-3 inches long ; flowers enlarged in fruit, 

 the loose calyx becoming ^ line long, with obtuse lobes, scarcely cari- 

 nate, not crested; fruit dark brown, the seed acutely margined. — 

 Northern Asia and reported from Alaska. The plant on which the 

 species was originally founded was doubtfully and probably erroneously 

 ascribed to Virginia.

 developing a broad transverse membranous wing. Stamens 5. Ovary 



* A third species was collected by Mandon (No. 1026) in the Ancles of Bolivia, 

 and may be named T. Mandoxi. It is stout, 1-2 feet high, glandular-puberu- 

 lent throughout; leaves rather thick, oblong-lanceolate, 2 inches long, sinuately 

 pi-anatifid; calyx-lobes strongly carinate, slightly crested, obtuse, appressed; 

 fruit dark brown ; seed obtusely margined.
