NEOROT, 
Riddell who sent it to me from New Orleans as 
an unknown G. with several other rare plants, 
he is the author of a Western Flora and disco- 
verer of many new plants there. If his name 
has been employed already, we may substitute 
Anti piiyla serrata Raf. 
757. Riddelia antiphyla Raf. Leaves 
smooth lanceolate acute, equaly serrate, petiols 
short pubescent, stipules subulate ; peduncles 
extraxilary unifl. equal to petiols, sepals colored 
linear lanceolate acuminate pubescent, petals 
subequal cuneate obtuse, * pod divergent strait 
equal to leaves — apparently a virgate shrub, 
branches fuscate terete rimose, leaves and pods 
uncial, almost opposite to each other, flowers 
yellow small, stamens 5 or 6, shorter than flow- 
ers. Pods fuscate smooth, seeds black com- 
pressed squared truncate. 
758. Sesuvium veruucosum Raf. prostrate 
roughened by warts, leaves thick petiolate obo- 
vate and cuneate obtuse entire, flowers axillary 
subsessile commonly solitary — a very distinct 
sp. with the habit of Portulaca oleracea, but en- 
entirely covered with rough tubercules and 
warts, when dry of a fulvous glaucous color all 
over, many branches, leaves small, flowers 1 to 
3 in the axils, campanuiate, white inside, sta- 
mens many, and thus totaly unlike the S. pen - 
tandrum of Elliot which is my G. Squibbia 
maritima. This sp. was sent me from Arkan- 
zas and the Chacta Country, where it grows 
near streams on the Yazou and Salt River. 
759. Spergula falcata Raf. Diffuse de- 
cumbent smooth glaucous, leaves linear falcate 
acute, base connate, peduncles axillary equal to 
internodes and leaves, erect, segments of calix 
ovate obtuse equal to petals and capsule. — On
