नीचे दिये गये प्रश्न के लिए अनुच्छेद

In flowering plants, different characteristics of a family are the diagnostic features which enable us to differentiate them. These diagnostic features are mainly based on floral characters like sexuality of flowers, symmetry of flowers, position of ovary with respect to flower whorls and conditions of calyx, corolla, androecium and gynoecium. For a systematic study and quick comprehension of all the diagnostic features of a family, those characters are symbolised and put in the form of a floral formula.

पुष्पी पादपों में, एक कुल के भिन्न अभिलक्षण नैदानिक लक्षण हैं जो हमें इन्हें अलग करने में सक्षम बनाते हैं। ये नैदानिक लक्षण पुष्प के चक्करों तथा केलिक्स, कोरोला, पुमंग तथा जायांग की स्थितियों के संदर्भ में मुख्य रूप से पुष्पों की लैंगिकता, पुष्पों की सममिति, अंडाशय की स्थिति जैसे पुष्पी अभिलक्षणों पर आधारित होते हैं। एक कुल के सभी नैदानिक लक्षणों के व्यवस्थित अध्ययन तथा शीघ्र समझ के लिए इन अभिलक्षणों को प्रतीक दिया जाता है तथा इन्हें एक पुष्पी सूत्र के रूप में रखा जाता है।
