54 NEW ZEALAND PLANTS. 
(fig. 28). The New Zealand jasmine (Parsonsia heterophylla), a pretty 
plant producing abundance of small sweet-scented flowers, is another 
very common twining liane. It occurs especially on the forest- 
outskirts, or where the forest has been partially cleared. It and 
its near relative, the small-flowered New Zealand jasmine (P. capsu- 
laris), may be recognized by the curious long green fruit, something 
like a kidney-bean in outward appearance. These plants are especi- 
ally remarkable for the diversity of forms assumed by their leaves 
at different stages of the plants’ development. These may be 
arranged into three series—viz., small round or oblong, long narrow,

and finally moderately broad and of an oblong type. Between the 
small round and the long narrow are all kinds of transitional forms. 
One variety of P. capsularis, as yet undescribed, never reaches the 
final adult stage, but produces flowers while in the narrow-leaved 
condition, and so it may perhaps be considered a fixed juvenile 
form of Parsonsia heterophylla. 
The mangemange (Lygodiwm articulatum) is an elegant climbing- 
fern, whose masses of tough slender stems twined round one another
