Cucurbitacese.âTlie best known member of the genus isââ T. dubia.âA native of India and China, having swollen tuberous roots and climbing stems 12 to 20 ft. long, furnished with pretty heart- siiaped hairy leaves. The yellow flowers are freely produced during the summer months, and in the case of the female plants are succeeded in autumn by bright red downy fruits about the size and shape of a hen's egg. {Bot. Mar/, t. 5469.). Fig. 320.âTliladiantha dubia^ seedlings. This species will grow well in the open air if planted against a south wall in the Midlands, or in any position in the mildest parts of the Kingdom. To secure a good supply of the bright red fruits, it must be remembered that the plant is dioe- ciousâthat is, the male and female flowers are borne on distinct and separate plants. Of course both kinds should be grown, as it is essential to have the pollen from the stamens of one plant to fertilise the pistils of the other. The plants may be increased by division of the root- stocks in spring, and from seeds sown under glass. T. Oliverl.âThis is a much finer and more vigorous plant than T. dubia, but has no tubers. The stems are 30 ft. long, the leaves are larger, and the flowers more numerous. {Rev. Hort. 1903, 472, f. 194.) THOMSONIA (after Dr A. T. Thomson, 1778-1849). Nat. Ord.
