HANSON MALVACEAE IN TEXAS 
some had not been previously collected in the United States. Ahutilon 
incanum was found commonly in the taller chaparral, in open woods, and 
as a weed in fields throughout the region. A. herlandieri occurred in the 
same habitats as A. incanum, but it was less abundant. A. jacquini was 
found only in small clumps, or scattered singly, in openings in the palm woods 
between Brownsville and the Gulf. Only one clump, composed of about 
20 plants, of ^. peduncular e was found, in a small opening in the palm woods 
below Brownsville. A. triquetrum formed large clumps in openings in the 
palm woods and was found rarely in mesquite and huisache woods within a 
few miles of Brownsville. A few plants of A . wrightii were found on the shell 
point extending into the bay between Portland and Corpus Christi. Bas- 
tardia viscosa was found in very limited numbers in only one locality, in 
prickly pear and mesquite on the shore of a lake east of Brownsville. Cal- 
lirrhoe digitata occurred abundantly in low thickets in the vicinity of Corpus 
Christi. Cienfuegosia sulphur ea was found commonly on low, moist, black 
clay soil in the vicinity of Corpus Christi, Taft, and Gregory. It appears 
to have spread considerably since Heller (8) found it at Corpus Christi in 
1894, and Lewton (11) found it at Taft in iQio after considerable searching. 
The thick, woody tap root of the plant makes it a persistent weed in low 
parts of cotton fields. Hibiscus cardiophyllus was found rarely in mesquite 
woods near Brownsville, rarely on the dry clay banks of the Arroyo Colorado 
near Harlingen, and rather frequently in the chaparral west of Harlingen. 
In places it is cultivated for its pretty red flower. Malachra capiiata was 
found only in the Brownsville region, occurring rarely in openings in the 
palm woods, on the borders of the willow woods along the Rio Grande, 
and as a weed in fields. Malva parvifolia occurred very commonly and 
abundantly as a weed in towns of this section. Malvastrum aniericanum 
was found commonly in woods and as a weed in fields and yards. M. 
spicatmn was found frequently in open woods, on the edges of woods, and 
as a weed from Brownsville to Mission. In very open woods of mesquite, 
huisache, and Texas ebony along a lake near Brownsville, M. americanum 
and M. spicatum were the dominant plants under and between the trees. 
M. wrighlii was common and abundant in open mesquite and as a weed 
along fences and roads in the vicinity of Corpus Christi. Malvaviscus 
drummondii was very abundant and common in the palm woods and in 
thickets along the Rio Grande and in the woods near Corpus Christi. 
It is often cultivated for its odd red flower and red berry-like fruit. Modiola 
caroliniana was found very rarely in low, moist, open places near Browns- 
ville. Sida angustifolia and 5. spinosa were found infrequently as weeds in 
fields and in open woods. 6*. ciliaris was found in open woods and as a weed 
in fields and lawns from Riviera to Gregory. 5. filiformis and S. diffusa 
were found frequently in open mesquite woods and in openings from Browns- 
ville westward. S. hastata occurred commonly as a weed in towns and in 
open chaparral from Brownsville westward. S. cuneifolia was found abun-
