Talk:Rhodocactus sacharosa

Origin of sacharosa
Grisebach merely says that "sacharosa" is a vernacular name. It's a noun in apposition, shown by his use of a capital letter, then used for nouns (and adjectives derived from the names of people and places), so it doesn't change its ending, and "Rhodocactus sacharosus" in some sources is wrong. In South American Spanish, sacha means false or sham according to this source, so sacharosa could mean 'false rose'. In Quecha, sacha means 'tree' according to this source, so treating rosa as a Spanish adjective, sacharosa could mean 'rose tree'. However, this is speculation, and I haven't found a source to support either meaning. Peter coxhead (talk) 18:33, 1 May 2021 (UTC)
 * I've now found a source and added it to the article, although it doesn't seem aware that the South American Spanish sense of sacha is not quite the same as the Quecha sense (although, speculatively, might be derived from it). Peter coxhead (talk) 11:13, 2 May 2021 (UTC)
