Lectotypification.

Lindau cited Rusby 1117 and Kuntze s. n. from Santa Cruz as types of Chaetochlamys rusbyi . Assuming he saw these collections in Berlin, they would have been destroyed in 1943 so Rusby 117 at the BM has been selected as lectotype. It is not a holotype as suggested by Tropicos. Wasshausen and Wood (2004) cited Hassler 1936 (G) as lectotype of Beloperone matthewsii , but there are three sheets at G so a unique sheet (G- 00102447) is here designated as second step lectotypification.
