Simple leaves subsessile, linear to elliptic‑linear, 1.9–3.2 × 0.3–1 cm, similar to leaflets or petiole of compound leaves. Compound leaves: petiole winged, 2.7–11.5 × 0.3–1.5 cm, oblanceolate, lepidote; leaflets subsessile, oblanceolate, 1–4.5 × 0.3–1.2 cm, base cuneate to broadly cuneate, apex rotund or emarginate, margin entire, lepidote and glabrous on both surfaces. Flowers solitary or in clusters of 2 on stems. Pedicels lepidote, 5–8 mm. Calyx divided to base, lobes 2, ovate, 1.5–2 cm, subequal, glabrous, slightly lepidote at base, often with impressed plateform glands. Corolla yellowish brown, with purplish red patches and stripes, campanulate, swollen at one side, tube 2.8–5.5 cm; limb 5‑lobed, lobes broadly triangular, 1–1.5 cm, apex mucronate, glandular‑lepidote abaxially. Fertile stamens 4, slightly exserted, thecae partly divergent. Ovary conical, glabrous and lepidote, 5–6 mm; ovules in many rows on 4 lateral placentations. Style filiform, exserted. Berries subglobose, 7 –10 cm. Seeds small, thin, 6–7 × 7–9 mm, not winged. 中國植物誌: 小灌木,高3-6米,胸徑15-25厘米。葉簇生於小枝上;小葉3枚,長倒披針形至倒匙形,幾無柄,側生小葉2枚,長1.5-6厘米,寬1.5-2厘米,頂生小葉長5-8厘米,寬1.5-2厘米;葉柄長4-10厘米,具闊翅。 花1-2朵生於小枝或老莖上;花梗長約1厘米。花萼2裂達基部,淡紫色。花冠褐色,具有紫褐色脈紋,近鐘狀,具褶皺,喉部常膨脹成淡囊狀,長5-7厘米,簷部成五角形。雄蕊4,插生於花冠筒下部,花藥個字形著生,外露。花盤環狀,淡黃色。花柱長6厘米,柱頭薄片狀,2裂;子房淡黃色。果近球形,直徑 5-7厘米,光滑,不開裂,淡綠色。 | |
