| 備註: 花5-20朵, 花序蝎尾狀 -- 黃果龍葵_瑪瑙珠 S. diphyllum 花1-3朵, 很少成蝎尾狀花序 -- 珊瑚櫻_吉慶果 S. pseudocapsicum 標室: 瑪瑙珠Solanum pseudocapsicum var. diflorum 圖片應是黃果龍葵Solanum diphyllum kplant.biodiv.tw: 高約 1 公尺，莖枝細直，黑綠色，分枝甚多，嫩枝上面有密密的短毛。單葉互生，不具托葉，表面平滑，倒披針形，稍彎曲，全緣；葉緣不規則波狀；葉面濃綠，葉背淡綠，搓揉葉片可聞到特殊腥味。白花，花後立即結果(漿果)。幼果綠色，成熟後漸轉成橙黃色、橘紅色，果熟期為 4~10 月。果實直徑通常在 1 公分以下，在分類上也是一種漿果，成熟前呈綠色，成熟後轉為橙黃，但因果皮較薄，抗旱力稍差，果實未脫離母株前，就會有乾癟皺縮的現象。瑪瑙珠的果實雖然晶瑩剔透，外觀漂亮，但是不可誤食，可避免中毒的危險。漿果，種子多又細小。 FOC: Solanum diphyllum Linnaeus Shrubs glabrous. Stems erect, 0.5-2 m tall, young stems angled proximal to nodes from decurrent leaf bases, otherwise terete. Leaves unequal paired; petiole of major leaf 1-1.5 cm, winged by leaf bases; blade of major leaf elliptic to oblong, sometimes broad, 4-9 × 2-3.5 cm, base attenuate and decurrent on petiole and stem, margin entire, apex rounded; minor leaves subsessile, blade rounded, 1.5-3 × 1.2-2.2 cm, entire. Inflorescences leaf opposed, short scorpioid racemes, often subumbellate; peduncle unbranched, 3-12 mm, later bearing conspicuous pedicel scars. Pedicel 5-12 mm, erect at anthesis. Calyx constricted at base and just proximal to lobes, 2-2.5 mm; lobes deltate, ca. 1 mm, minutely ciliolate. Corolla white, 3.5-4.5 mm, lobed ca. 3/4 way to base. Filaments short; anthers 1-1.5 mm. Ovary glabrous. Style 3-4 mm. Fruiting pedicel erect, 0.8-1.4 cm. Berry orange, globose, slightly 2-lobed, 7-12 mm in diam. Seeds yellow or tan, reniform-discoid, ca. 3 × 2 mm, margins thickened. Fl.
