同意vandas版主,是復活節仙人掌“Easter Cactus” 。
同大多數仙人類植物一樣,蟹爪蘭莖葉嚴重變態成節片,形同蟹足。葉狀莖扁平肥厚,卵圓形,呈鮮綠色,邊緣具粗鋸齒是「聖誕仙人掌Christmas Cactus」 (照片A),邊緣圓齒形是「復活節仙人掌EasterCactus」(照片B)。有小刺着生於上,先端截形。莖節的頂端往往同時着生2-3個花蕾,但通常只有一朵能開放,其它的會自然脫落。花着生於葉狀莖的頂端,花被兩層開張反卷,花色有淡紫、黃、紅、純白、粉紅、橙、藍和雙色等。兩性花,雄蕊多數。

The biggest difference between a Christmas cactus and an Easter cactus is when they bloom. Each blooms near its respective holiday. Christmas cactus have scalloped stem segments. Thanksgiving ones have between two and four pointy teeth along the edges of leaves and Easter cactus have rounded teeth. They are members of the Zygocactus truncatus family which is native to Central and South America. You might also see them referred to as ‘Jungle cactus’. |
