In the original description of Lagarinthus corniculatus Meyer (1837) cited two collections (Drège 3423 and Drège s.n.). Drège s.n., from the grassy hillsides at Katberg was not traced. The only duplicates of Drège 3423 were found at at K and P (scan). As the specimen from P is more complete it is chosen as lectotype. The material from K was examined and despite it being only a fragment the identity could be confirmed to be this taxon, based on the flowers only.

Schlechter (1894c) only listed the collection of Barber 293 when he newly described Gomphocarpus stenoglossus of which two specimens could be traced at GRA and K. The material from K is here selected as lectotype as it represents the full facies of the species better and is more representative of the species than the sheet from GRA. It was interesting that N.E. Brown wrote on the GRA specimen: “Mr. Bowker & Mrs Baber were brother and sister relations and the same plant with the same number appears to have been distributed sometimes under the one name and sometimes under the other” hence the correction of the label at K from Bowker to Barber.
