Abstract
أكدت الدراسة التصنيفية لجنس Ornithogalum L. الصلصال ( نجم بيت لحم ) تسجيل 4 أنواع تابعة له هي: O.narbonense L., O.montanum Cyr., O.umbellatum L., O.ulophyllum Hand.. لأول مرة في منطقة جبلة، وتم وضع قاعدة بيانات مورفولوجية تضمنت ( الشكل الحياتي - والأبصال - والبصيلات المحيطة بالبصلة - والأوراق– ووجود الخط الأبيض على الوجه العلوي للورقة – والخط الأخضر على الوجه السفلي للتبلات - والأسدية – المدقة – والثمار – والبذور - مع نمط حبات الطلع وأبعادها، وتحديد نمط الثغور ), وربطت هذه الصفات باستخدام برنامج الإحصاء Statistica للحصول على شجرة النسب Dendrogram التي بينت وجود 3عناقيد, عنقود مشترك للنوعين O.narbonense, O.ulophyllum، بينما انفرد كل من النوعين O.umbellatum O.montanum, بعنقود خاص به, ووضع مفتاح تصنيفي للتميز بين الأنواع المدروسة. Taxonomic study confirmed of genus Ornithogalum L.
