A detailed description of ovule development and embryology of Hemiphyl
acus alatostylus is given, together with a chromosome count and karyot
ype. Comparative data are presented for Asparagus and Anemarrhena, sin
ce earlier analysis of rbcL sequence data indicated a relationship bet
ween them. Hemiphylacus should be included in Asparagaceae. A close re
lationship between them is strongly supported by rbcL analysis, and th
ey are further linked by the shape and histology of the fertilised ovu
le. However, both morphological and molecular data indicate that Anema
rrhena is a more isolated taxon.
