3.西疇酸腳杆 Medinilla fengii (S. Y. Hu) C. Y. Wu et C. Chen
小灌木,高50-120釐米,通常附生於樹上,分枝多;莖近圓柱形或鈍四棱形,常因具皮孔而粗糙,無毛。葉片紙質或近堅紙質,倒卵形至橢圓形,頂端漸尖或近尾狀漸尖,基部楔形,長4-10釐米,寬2-3.5釐米,全緣或具疏細鋸齒,3基出脈,葉面密佈網狀小窩點,基出脈下凹,背面密佈糠秕狀小突起,以基出脈上較明顯,基出脈隆起,側脈不明顯,葉柄長5-12毫米,具槽。由鬆散的傘房花序組成小圓錐花序,頂生,有花3-6(-16)朵,長2-3釐米,寬3-5釐米;苞片極小,早落;花梗長5-10毫米,花萼長約5毫米,漏斗形,無毛,具密小突起,裂片4,卵形,長約2毫米,頂端圓形,具小尖頭;花瓣4,微粉紅色,廣倒卵形,長約6毫米,於右上角突出1小片,頂端近平截而微凹,具小圓突起,雄蕊8,幾等長,花藥基部具鑽形小突起,藥隔基微下延成短距;子房下位,頂端具數齒,4室,無毛。漿果壇形,長6-7毫米,直徑4-5毫米;種子多數,倒卵形,光滑。花期約6月,果期10-12月。
產雲南東南部。生於海拔650-1500米的山谷密林中、灌木叢中、溪邊石縫中或附生於樹上。模式標本采自雲南西疇。
本一種與紅葉酸腳杆M. erythrophylla (Wall.) Lindl. 相近,但本種枝紅褐色,具朋顯的皮孔;萼片卵形,長約2毫米,花瓣於右上角突出1小片;雄蕊花藥基部具鑽形小突起,藥隔基部下延呈短距,可以區別。
