Fumaria: what to photograph for the identification

Fumaria is usually considered a difficult genus as far as identification is concerned. It is mainly due to the small size of the characters that are useful for the identification and for the fact that often both flowers and fruits are needed.

I would be happy to try to help those iNat users that would like to get more insight into the identification of fumitories.

Here it is a brief list of characters tat are needed for the identification of fumitories.

1) corolla color, shape and length
2) upper petal shape
3) sepals shape and size (length and width)
4) dry fruit shape and size (length and width)
5) pedicel shape (straight, spreading or reflexed) and length at frutification
6) bract length and bract/pedicel ratio
7) flowers number for each inflorescence
8) peduncle/inflorescence ratio
9) leaflets shape

- characters 1, 3, 4, 5 and 6 should be measured and photographed with a linen tester or a stereomicroscope and a sheet of millimeter paper

- fruits shape (surface smooth or rugose; overall shape) should be evaluated when fruits are dry. To do this, just put an infructescence in a paper bag or let it dry with some kitchen paper inside a book.

This post represents an example of how a Fumaria must be photographed for its identification:

iNaturalist Toscana: escursione annuale?

L'idea è quella di organizzare delle escursioni congiunte in varie località della Toscana particolarmente interessanti per il patrimonio naturalistico che le caratterizza.
Per non rendere il tutto troppo impegnativo ho pensato che tali ritrovi potrebbero avere cadenza annuale però niente vieta di organizzarli anche con frequenza maggiore.
Che ne pensate?
