Veronica anagallis-aquatica L. var. pseudoanagalloides Gren.

Flore de la chaîne jurassique: 579 ( Grenier 1869).

TYPE CITATION. — France, Jura: “ V. anagalloides Michalet exsicc. Fasc. 1, no. 29 et non-null. auct.; V. fallax Gren. ined.”.

LECTOTYPE (designated here). — “ Bords des mares et fossés Asnans et Longwy , canton de Chaussin - Alluvion du Doubs”, Michalet no. 29, 30. Aug. 1855 P[ P04575448 *] .

ISOLECTOTYPE (designated here). — P[ P04040347 *].

Nomenclatural note. This species and its close relatives are notoriously polymorphic and difficult to identify. The specimen of Michalet can be identified by the bracts being longer than the pedicel, the latter spreading at wide angle from the stem. Also, the description, peduncle, and pedicel glandularhairy, supports the identification as V. catenata Pennell. While the lectotype bears a label indicating that it was given to P by Grenier in 1875 (but also the stamp of herbier Camus), the isolectotype has no indication of how it came to P.
