Kartieraufruf Veronica "catenatoides"

Beitrag von Kraichgauer »

Hallo zusammen,

Bob Travnicek hat in CZ einen Doppelgänger von Veronica catenata gefunden, der dort und in Österreich ziemlich regelmäßig vorkommt. Er vermutet jetzt, dass dieser auch in D zu finden ist. Deswegen sein Kartieraufruf unten.
Bob kommt Anfang August zum Rubus-Konzil bei mir um die Ecke, so dass evtl. Belege am besten an mich zu schicken sind, sofern sie vor Ende Juli bei mir eintreffen.

Danke für die Mithilfe und Gruß, Michael


Dear friends from Germany,

I would like to ask you for your help to search for a newly distinguished taxon from the
Veronica anagallis-aquatica range in Germany. This type occurs quite often in the warmer
regions of the Czech Republic (Morava and Silesia, Polabí in the Czech Republic) and its
occurrence in Germany is very likely. The type is close to the species V. anagallis-aquatica s.
str. and V. catenata and, like both of these species, it is also tetraploid (V anagalloides and V.
scardica stand more apart). It can cross with both V. catenata (hybrids are completely sterile,
do not form capsules) and V. anagallis-aquatica (hybrids are sterile or partially form
capsules). The type occurs both on bare moist soil (edges of ponds, banks of ponds and
sandpits, field wetlands) and in muddy slow-flowing streams (with Berula erecta or
Nasturtium). It can be distinguished by the following key:

1a) Inflorescence completely without stalked glands; C pale blue or pale blue-violet; the
lowermost leaves of first-year plants (and leaves of its lateral ground branchs) with short
petiole and with blade obovate to roundly obovate; stem leaves widest +/- in the middle. -
Fruit peduncles point in arc upwards, the lowermost peduncles of racemes usually
significantly longer (most often +/- 2x) than bracts; capsules usually slightly longer as wide
....V. anagallis-aquatica

1b) Inflorescence at least with flower (fruit) peduncles with stalked glands; also the
lowermost leaves of first-year plants (and leaves of its lateral ground branch) usually without
petioles and with blade narrowly oblong or oblong-oblanceolate; stem leaves usually widest
in lower part (lanceolate to broadly lanceolate)...................2

2a) Stalked glands presents on flower (fruit) peduncles, on axis of inflorescence racemes
and also on capsules (ovaries)
, stalk of glands usually short; fruit peduncles point obliquely
to sides
, the lowermost peduncles of racemes usually +/- as long as bracts; capsules usually
as long as wide; C pale pink .... V. catenata

2b) Stalked glands presents only on flower (fruit) peduncles, sometimes also in upper part
of axis of inflorescence racemes, but never on capsules (ovaries),
stalk of glands relatively
long; fruit peduncles point in arc upwards, the lowermost peduncles of racemes usually
significantly longer (most often +/- 2x) than bracts; capsules usually slightly longer as wide; C
whitish pink (pale lila - +/- as V. serpyllifolia) ..... V. "catenatoides"

I send you photos of this interesting taxon (V. "catenatoides") as attachment.
I will be happy if you also ask your botanical friends who are interested in the wild plants to
look for V. "catenatoides".
Thanks in advance for any help on this matter.

With best wishes, Bob
