leafy throughout, slightly flexuous, strongly channeled, woody 
below; leaves lanceolate or oblong-lanceolate, 6-13 cm. long, 
1.5—4.5 cm broad, acute or sometimes attenuate at the apex, the 
lower ones obtuse or truncate at the base, the upper acute or 
acuminate at the base, all rather long petioled, coriaccous, light 
green, undulate and crisped, neither prominently nor conspicu- 
ously nerved; petioles strict, 2-5 cm. long; orceae cylindric 
nearly one half as long as the internodes; inflorescence terminal, 
simply paniculate, naked; racemes (fruiting) 5-12 cm. long, 
dense, rather erect, the terminal one- usually about twice as long as 
the lateral ones ; calyx 2 mm. broad ; pedicels varying from 2-4 
mm. in length, jointed below the middle; wings broadly ovate 
cordate, broader than high, 1 cm. long, I-1.2 cm. broad, straw- 
colored, sometimes slightly constricted below the apex, conspicu- 
ously and prominently nerved, crenulate and undulate, each one 
bearing an oblong-ovoid callosity, the three wings strongly spirally 
twisted ; achene broadly oblong-ovoid, 3 mm. long, short-pointed, 
chestnut colored, its faces nearly flat, its angles conspicuously 
margined. Plate 228. 
Found growing in the mud on the margins of ponds near 
Kenedy, Carnes county, Texas, by Mr. A. A. Heller, collected in 
flower and fruit on May 26, 1894. The altitude of the station is 
about 400 feet. Ao. IDS! | 
Its nearest relative is Rumex altissimus, from which, however, 
it differs in having more characteristically lanceolate leaves, which 
are longer-petioled, crisped and the larger ones more or less trun - 
cate at the base instead of acuminate. The panicle of &. spiralis 
is more open, not leafy, and its racemes are denser and thicker. 
Wings twice to thrice as large as in X. altissimus invest the broadly 
oblong-ovoid achene. The former are broader than high and 
strikingly cordate, whereas those of &. a/tissimus are higher than 
broad, not strongly cordate and less prominently nerved. So far 
as observed three callosities are developed throughout.

The range of this species, heretofore confined to the upianre 
and foot-hills in South Carolina and Georgia, has now been ex: 
tended into the low country by its discovery by Miss samt:
