Platylobium ID confusion

[Suecee]

Platylobium obtusangulum and Platylobium formosum look similar bar the leaf shape (to me). There have been no records of Platylobium formosum entered in the Biodiversity Blitz 2021 City of Frankston and 9 neighbouring councils except for Knox and Yarra Ranges. Just wondering if we have incorrect ID’s with some of these plants. (Newbie)

I know nothing about those plants, but I know something about iNaturalist data. If two organisms look similar, they will be confused by some users. If someone has an interest, he/she can look over the relevant observations, correct or confirm some, or change some to the genus level. Hopefully that person will write up some short explanatory paragraphs to paste into the observations being identified.

I’ve done this for some taxa that interest me. It’s kind of fun. Well, low key, highly repetitive sort-of-fun. Anyway. It’s really valuable to iNaturalist and to people who use the data. Because we’re all volunteer identifiers, that’s how these problems get fixed here. (Obviously, some wait a l-o-n-g time to get fixed.)

welcome to the forum :)

The VicFlora key for Platylobium actually does not list P. formosum at all (although oddly PlantNET indicates it is found in Victoria).

quotation: "

Plants previously known as P. formosum in Victoria are now P. infecundum, P. montanum, P. parviflorum, P. reflexum or P. rotundum. See I.R. Thompson, Muelleria 29(2):154-172 (2011).

Platylobium formosum in the strict sense grows naturally in NSW and SE. Qld (not in Vic.).
NSW PlantNet has some parts out of date; VicFlora get updated more (in my experience and discussions).
