A very polymorphic species, closely allied to H. organifolium. Although very difficult to classify satisfactorily, it can be divided as follows:
1. Stems scabrid to puberulous ………………………………..subsp. byzantinum
1. Stems glabrous
    2. Leaves shortly pubescent; petals usually with some black glandular streaks .....subsp. uniflorum
    2. Leaves glabrous to papillose-puberulous; petals with black glandular dots only
        3. Stems usually erect, 30-60 cm; leaves oblong to linear ; inflorescence many- flowered, pyramidal to narrowly cylindric
        4. Sepals ribbed, obtuse to rounded or glandular-mucronate; leaves 20-35 mm; petals sometimes white or  pinkish …….subsp. aviculariifolium var. albiflorum
          4. Sepals plane, acute or subacute; leaves 10-20 mm; petals always yellow, sometimes red- tinged ….subsp. aviculariifolium var. aviculariifolium
     3. Stems usually decumbent to prostrate, 5-20 cm; leaves oblong or elliptic to obovate ; inflorescence 1-many-flowered, pyramidal or cylindric to subcorymbose   
         5. Stems suberect to ascending; inflorescence usually pyramidal to cylindric, many-flowered  .subsp.  depilatum var. depilatum
            5. Stems decumbent to prostrate; inflorescence usually subcorymbose to 1-flowered 
              6. Sepals acute ………………………………….subsp. depilatum var. leprosum
