The Lectotype of Lepianthes Raf. (Piperaceae)

Taxon, 1987
SummarySince Howard (J. Arnold Arb. 54: 380. 1973) did not designate a lectotype for the generic name Lepianthes Raf., it is argued that the first explicit and effective lectotypification of the name is Lepianthes granulosum (Ruiz & Pavon) Raf.

THE UNNECESSARY CONSERVATION OF GENERIC LECTOTYPES

TAXON, 1981
SummaryIt is contended that the proposed conservation of such lectotypes as that of Bombax ceiba L. for the genus Bombax is unnecessary. To insist that the type of a genus must conform completely with the generic protologue is an unreasonable requirement. The lectotype of the genus Jatropha L.

Lectotype Designations in the New World Myrmeleontidae

The Canadian Entomologist, 1961
During the month of August, 1960, I had the opportunity of studying the extensive collection of ant-lions at the Museum of Comparative Zoology, Harvard University. This collection contains most of the type material of Nathan Ranks and Hermann Hagen. In many cases only syntypes were present which necessitated the desicgnation of lectotypes.
