Petals 8-15 mm, with black marginal and black or amber superficial glands. Capsule 5-10 mm, with dorsal vittae and lateral vesicles.

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 -length/breadth ratio 1,5-3-; 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
