Su Kuna [7th cent.]:—It twines around herbaceous 
plants and trees. The stem and the leaves are of a purplish 
red colour. The old stem has a thin epidermis, and the young 
stem is covered with hair. The leaves resemble those of 
the ku tow (pea), tomentose on both sides. Flowers white 
with purple filaments (anthers). This plant is sometimes 
confounded with the lo shi [see 189], but that is another 
plant. 
Li Sut-cHen :—The jen tung is a climber. Its stem has 
a tinge of purple. The leaves proceed in pairs from the 
joints. They resemble the leaves of the pi li [see Bot. sin., 
Il, 415] but are hirsute. It blossoms in the 4th month. 
The flower is more than an inch long. One peduncle pro- 
duces two flowers. The corolla has two lips, one large 
and one small. It looks like one-half of a flower. Long 
filaments. The flowers when they first open are all white, 
but after two or three days they become yellow. Owing to 
the plants producing yellow and white flowers at the same 
time it is also called & $8 4 kin yin hua (gold and silver 
flowers). The flowers are very fragrant. They are gathered 
for medical use in the 4th month and dried in the shade. 
The leaves are gathered at all times of the year. Other 
names for the plant are ZF #¥ RE yaan yang t'eng, BE HE | lu 
te! teng, 3% BH lao weng si, MH | ch‘ant'eng, & W BY
