57a. 直角莢蒾　Viburnum foetidum Wall. var. rectangulatum (Graebn.) Rehd.

植株直立或攀援狀；枝披散，側生小枝甚長而呈蜿蜒狀，常與主枝呈直角或近直角開展。葉厚紙質至薄革質，卵形、菱狀卵形，橢圓形至矩圓形或矩圓狀披針形，長3-6 (-10) 釐米，全緣或中部以上有少數不規則淺齒，下面偶有棕色小腺點，側脈直達齒端或近緣前互相網結，基部一對較長而常作離基3出脈狀。總花梗通常極短或幾缺，很少長達2釐米；第一級輻射枝通常5條。花期5-7月，果熟期10-12月。

產陝西南部（城固）、江西、臺灣、湖北西部、湖南、廣東北部、廣西北部、四川、貴州、雲南及西藏東南部。生於山坡林中或灌叢中，海拔600-2400米。模式標本采自四川南川。 Viburnum parvilimbum Merr. 的模式標本 F. A. McClure 00616 與本變種沒有什麼兩樣，T. Dudley 在注釋標籤上予以歸併的做法是正確的。從本變種的現有地理分佈資料來看，它之在粵北出現亦非意外之事。 H. Handel-Mazzetti 所發表的臭莢蒾 V. foetidum Wall. 的二個變種——var. penninervium 和 var. malachotrichum（前者葉的側脈4-6對，羽狀，邊緣具較大的牙齒狀鋸齒；後者的幼枝、葉和花序均被絨毛）實際上都同本變種有過渡而難以區分，故併入本變種內作為異名。
