Vicia hirsuta, Diemer Bos
“head” and rear end
Vicia sativa, Nieuwendam: front and rear spraculum, lateral
Vicia hirsuta, sativa: rear spiracula, dorsal, and one rear spiraclum, seen from the median line
Vcia sativa: mandibles
The sausage-like, curved papillae of the rear spiraculum are quite remarkable. Already de Meijere (1938a) had observed them, in material from Switzerland.
