The Sand-binding Plmts 
[no. 1, NirV\' SERIES, 
their milk is tainted. Great difficulty occurs in raising this plant 
in the vicinity of houses — as the inhabitants tread it down, and 
cattle nibble the tender shoots. It naturally takes a higher posi- 
tion on the sand-bank than the Spinifex, and suffers less in- 
jury during a storm, but they often grow together and conjointly 
effect much benefit. The Spinifex arrests the drifting sand, 
and the Ipomoea secures what the former collects. Mr. Cadell 
has planted it most extepsively along the Canal banks near Tran- 
quebar. (Plate No. 3). 
3. Canavalia ohtusifoUa D. C. conjmon on the sea-shore, 
frequently entwined with the last named binder, this is also a very 
useful plant, and is very abundant at the Adyar, Ennore, the 
mouth of the Godavery, and between Quilon and Anjengo. (Plate 
No. 4). 
4. Hydropliylax maritima, Linn. Seaside Hydrophylax. A 
straggling herbaceous plant, native of the shore of Coromandel, 
where it shows its pale lilac blossoms great part of the year. The 
branches run over the sand, sometimes under the surface, and 
strike root at the joints. It answers well when the sand is moist. 
Figured in Roxb. Cor. pi. t. 233. 
5. Micr orhy ncluis sarmentosus, '^ig\\t. A widely diffused hum- 
ble plant, common along the sea beach, with long flagelliform run- 
ners ; but according to my observation, no species of the Compo- 
site possesses sufficient strength to effect the object in view. It is 
well figured in Wight's illustrations, Vol. II., t. 133. (Plate No. 5). 
6. Pupalia orhiculala, Wight. Achyranthes orhiciilafa, Heyne, 
Walllch, Cyaihula orhiculata, Moquin, " stem prostrate : leaves 
short petioled densely villous when young, becoming orbicular, re- 
tuse, acute at the base, smoother by age : fascicles densely tomen- 
tose, many-flowered, globular, remote, with long brown bristles."

On sandy soils near the sea beach, abundant at St. Thome, and 
near the mouth of the Adyar River. 
An extensively spreading procumbent plant, the branches being
