—in Arkanzas and Texas, perennial, pedal 
slender, leaves very narrow half uncial, raceme 
terete uncial, flowers white small, on short pe- 
dicels almost imbricate, bracts lanceolate : this 
sp. may be a Muraltia , I cannot determine the 
stamens. 
986. Polygala (Sexilia) missurica Raf. 
stem branched diffuse 4gone, leaves quaternate 
and opposite broad lanceolate smooth, base 
acute, end mucronate ; spikes terminal oblong 
imbricate— in the prairies of Missouri and Illi- 
nois, 3 to 4 inches high, leaves larger and 
broader than in others, flowers white, not in fili- 
form spikes. Annual. 
967. Polygala (Muraltia?) rug os a Raf. 
stems angular prostrate, leaves alternate rugose 
lower cuneate obtuse, upper linear cuneate acute, 
flowers in slender spikes — on Lake Michigan, 
humble, 3 to 6 inches long, leaves less than one 
inch, flowers red, sessile in short spikes ; but 
very imperfect in my specimen, probably a Mu- 
raltia. 
968. Polygala or Pilostaxis hyemalts 
Raf. stemless, leaves all radical obovate obtuse 
capitule sessile squarrose oval, bracts lanceolate 
membranaceous as long as flowers — this and 
the next are blended in P. lutea var. nana of 
Mx. but quite unlike our P. lutea of New Jer- 
sey. Found by Baldwin and Nuttal in Florida 
and Georgia, blossoming in January, leaves un- 
equal uncial often spatulate, heads shorter than 
leaves, flowers greenish, root annual. 
969. Polygala or pilostaxis nana Raf. sub- 
scapose, leaves cuneate and oblong, obtuse and
