throughout, freely branched, the branches paniculately branched, 

 low and spreading, about i^"" high (broader than high): leaves 

 entire, from oblong to linear, mostly acute, some of them short 

 pctioled, 1-2'^'" long: floriferous throughout ; the small clusters 

 in dense panicles which are naked towards the apex : calyx 

 thickened with the dense mealiness, brittle, enclosing the fruit, 

 the large (more than i"""") shining-black seed easily separable 



I from the pericarp.

(wholly typical as represented in the Rocky Mountain Herbarium), July 29, 

 1S96, may be designated the co-type. 



Chenopodium cycloides, n. sp. — Animal, about 4*^"^ high,stout- 

 ish, divergently branched from near the base, nearly glabrous: 

 leaves narrowly linear (the early ones wanting), 5-25""™ long, 

 scattered on the branches or more crowded on slender branch- 

 I lets, lightly scurfy on both sides: sepals 5, not scurfy, mem- 



branous, at maturity somewhat united and spreading, simulating 



a rotate wing about the large brown depressed or lenticular 

 fruit: pericarp thin, close-fitting, transparent: seed more than 

 jmm broad, embryo annular. 



Of this seemingly remarkable distinct species I have seen but one collec- 

 tion, no. 435, by A, S, Hitchcock, Sand hills, Grant co., Kansas. It was 

 distributed as C. leptophyllum, to which it is most nearly related, notwith- 

 standing its very different appearance. The habit of the plant and its 

 winged fruits at first sight suggest a Cycloloma rather than a Chenopodium. 

 The type is the above number as it is found in the Herbarium of the Missouri 

 Botanical Garden ; the co-type, same number in the Rocky Mountain Her- 

 barium. 



DONDfA. 



In the transfer of the different species from Suaeda to 

 Dondia, there seems to have been some misunderstanding of 

 the synonomy. Dr. Watson in his Revision (Proc. Am. Acad. 

 9:87-90) seems to have had this perfectly clear, and there the 

 synonomy may be found in full up to that date. The following 

 new combinations seem to be necessary: 



Dondia Moquini (Torr.), n. comb. — Cheiiopodhia Moqinni Torr. 

 Pacif. R. R. Rep. 7:18. 1856 ; Suaeda Torreyana Wats. Proc. Am.
