THUNBERGIA THUNBERGIA 1799 sion: lvs. opposite: fls. blue, yellow, purple or white, solitary and axillary or in racemes; calyx annular and scarcely lobed or toothed or 10-15-toothed, surrounded by 2 large bracts which often inclose also the corolla- tube; corolla trumpet - shaped, with a spreading limb, tube curved or oblique, often compressed, enlarged toward the mouth; stamens 4, didynamous, fixed near the base of the tube, filaments thickened at the base,. 2500. Thunbergia alata (X separate; anther-cells parallel, equal, mostly nmerouate at the base: ovary seated on a fleshy disk, 2-loeuled, each cell with 2 ovules (rarely only one). The Thun- bergiese are distinguished by the contorted corolla, the 4-seeded capsule, and the globose seeds. The Thunbergias are nearly all vigorous greenhouse climbers resembling allamandas in habit. In large con- servatories where they are not cramped for room they flower freely and display their flowers to the best ad- vantage. Severe pruning, which is necessary in small greenhouses, prevents the production of flowers. The larger species, T. laurifolia, T. affinis, T. grandiflora, T. Mysorensis, and T. coccinea are rapid growers, re- quiring plenty of feeding and root-room. All do better in open beds than in pots. They may be propagated either from seeds or by cuttings which are taken from the young wood which starts into growth after the plants have been cut back during winter. These pro- duce few flowers the following autumn, but bloom freely the second season. As a rule, the plants flower in late summer or autumn, but this may be made to vary according
