CONVOLVULUS 
GENERAL—There are two varieties common in 
New Zealand, one of which has much larger leaves 
and flowers than the other. Both are found in most 
districts, growing in waste places and in gardens. 
When once established, it is most difficult to eradi¬ 
cate, and is consequently one of the worst of garden 
weeds. It is also called “Morning Glory” and 
“Bind-weed.” 
LEAVES—Shape, arrow-head shaped (similar to 
those of sorrel and arum lily). Stalks, relatively 
. short. Size, one to three inches in length. 
FLOWERS— Colour, white (the larger variety), 
. pink or purple. Shape, bell-shaped. Size, f to 1£ 
inches diameter. 
STEMS—Very long, twining stems with com¬ 
paratively few branches. 
NOTES—The perennial, underground, creeping- 
stems enable this plant to take possession of large 
areas in a short time. It is consequently one of the 
most serious plant-pests in New Zealand, if allowed 
to reach useful soil.
