1. Asparagus griffithii Baker in J. Linn. Soc. Bot. 14: 604. 1875.

R. R. Stewart Ann. Catalogue Vasc. Pl. W. Pak. Kashm. 50. 1972 has cited -Ghizr region, Gilgit, e. of Shandur Pass, Kerstan 2020. We have not been able to trace this specimen. R. R. Stewart (l. c.) has also stated that according to Wendelbo it is of doubtful status.

2. Asparagus deltae Blatter in J. Ind. Bot. Soc. 6(2): 70-71. 1927. .

S. Y. Kamble (J. Econ. Tax. Bot. 10(1): 163-166. 1987) has published a paper on the identity of Asparagus deltae Blatt. He has given the photograph of the Holotype (Gholam, Blatter 715 (BLATT) and claims to have examined all the other specimens of Asparagus deltae deposited in Blatter Herbarium. He has stated that the specimens are poor and lacking mature flowers and fruits, however, he found some seeds and a broken piece of inflorescence in the packet affixed to Blatt. 716 (BLATT). He found that there were only female flowers with very much reduced or no perianth or petals glabrous ovary and reniform 1.5mm long brown and papillose seeds. He did not f ind articulated pedicel, smooth and globose seeds, characteristic of Asparagus. He has come to the conclusion that Blatter wrongly identified Ochradenus baccatus Delile as an Asparagus. Hence Asparagus deltae Blatter is a synonym of Ochradenus baccatus Delile. The reasons advanced by Kamble are certainly convincing, but it is difficult to accept that Blatter could make such a mistake.
