Petiole 2.5-7 cm, hirsute with long adpressed hairs interspersed with glandular hairs. Stipules adnate to petioles with free apices.


Inflorescence
Branched, with 2-5 pseudo umbels, each with 4-14 flowers. Peduncle 2-6 cm, hirsute with curly appressed hairs and long glandular hairs, pedicel ~0.5 mm.


Sepals
5, lanceolate, posterior erect, others recurved. Hypanthium 28-65 mm.

Petals
Petals cream to pale yellow, posterior spathulate, apices obtuse to rounded with feather-like markings, 14-22 x 3.2-5.5 mm, anterior 11-18 x 2-4.5 mm.

Stamens
5 fertile, posterior 2-3 mm, lateral two 3-4 mm, anterior two 5-6 mm.

Distribution


Habitat

Not quite habitat, but excellent for a pint and heaps of history: Ye Olde English Pubbe in Matjiesfontein. The historic town is a good starting point for botanical explorations with a number of really interesting species frequently found just N of it: P. luteopetalum, P. moniliforme, P. stipulaceum, P. githagineum and many more. Most, if not all, populations resembling P. fissifolium north of Matjiesfontein and on the Roggeveld Plateau are in fact P. luteopetalum and the above distribution map, while based on Marais's Thesis, has been revised to reflect this.

Synonim

Note
For a key to pinnate-leaved, cream to pale-yellow flowering hoareas with stamens shorter than sepals see the
