A large number of specimens used as original material for the description of new species were destroyed in the bombing of the Berlin-Dahlem herbarium, B, in 1943. Six lectotypes are designated here for Cordia discolor Cham., Cordia multispicata Cham., Cordia tobagensis Urb. and its variety broadwayi Urb. in the Cordiaceae and for Tournefortia paniculata Cham. and Tournefortia ulei Vaupel in the Heliotropiaceae.

In the last ten years, several lectotypes have been designated in the Cordiaceae and Heliotropiaceae (Miller in
In the citation of types, the word photo refers to a print deposited in herbaria and the word scan refers to a picture posted online, available directly through herbarium sites, or through sites like JSTOR or Europeana.
As far as I could find out, the type material of the names in the Cordiaceae and the Heliotropiaceae treated below have been destroyed at B during World War II. Lectotypes need to be designated according to Art. 9.2. of the International Code of Nomenclature for algae, fungi and plants (

Brazil. 1814, F. Sellow s.n. (B† [F0BN000966, photo!]; lectotype, here designated:
Varronia polycephala Lam.
The name was given by Chamisso in 1829 to a northern South American shrub now recognized as a synonym of Varronia polycephala Lam. The material of C. discolor used by Chamisso and conserved at B was destroyed during World War II. I have seen the scans of the duplicates cited below as lectotype and isolectotype(s). Chamisso’s herbarium is in the collection of the Leningrad Komarov Institute (

I choose as the lectotype the specimen preserved at Kew because I was able to study it 1979 and in the 1990s.
