• Africa
• Arecaceae
• Miocene
• Palmoxylon
• Egyptian Siwa Oasis

Descriptions, comparisons and affinities are given for: Palmoxylon deccanense* SAHNI, P edwardsi* SAHNI, P geometricum SAHNI, pondicherriense SAHNI, P. prismaticum* SAHNI, P. pyriforme SAHNI and P sagari* SAHNI, based on the study of transverse and longitudinal sections prepared from the trunks according to well-known palaeobotanical techniques. All seven species are middle Miocene new records to Siwa Oasis, while those asterisked are new to Egypt. The number of palm stem species known from Egypt, accordingly, increased from 12 to 16 and that of Africa from 24 to 28. Brief comments on the macrofossil palm records of Africa particularly Egypt, palaeogeography and palaeoclimate are given. Stems are the dominant fossil palm organs in Africa and particularly in Egypt. Based on our present knowledge, Egypt is the richest African country in the number of recorded macrofossil palm remains.
