Sesleria interrupta Visiani (1842: 87)

Lectotype (designated here):— CROATIA. Split-Dalmatia: Ad rupes prope Oneum, sine die, Visiani 324 ( PAD0023202 !). Fig. 4 .

Other original material examined: — CROATIA. Split-Dalmatia: “ Sesleria 223 S. interrupta . N ° 42 ” Visiani 324 ( PAD 0023201!); “ S. tenuifolia ss capillaris mihi ”, In rupib. montium propae Admissa, sine die, Visiani 971 ( PAD!); S. interrupta Vis. Almissa a rupes, sine die, Visiani 971 ( PAD!); Dalmat., sine die, Visiani 343642 ( PR).

Notes:— Visiani (1842) described S. interrupta on the basis of material collected in Turnasa (a low hill with a castle located behind Omiš), along the river Cettina (“ In rupestribus loco Turnasa dicto secus flumen Cettina prope Almissa ”). Specimens of S. interrupta collected by Visiani were found in PR (one) and PAD (four). The PR specimen bears three pieces of a single individual collected in Dalmatia, all matching the diagnosis. In Visiani’s herbarium in Padova ( PAD) (Lorenzoni 1983) two gatherings were found. The first (No. 971) bears two labels. The left label is older and was probably affixed when Visiani collected the specimen near Almissa (the ancient name of Omiš). This label bears the text “ S. tenuifolia ss capillaris mihi. In rupib. montium propae Almissa”. On the right label in Visiani’s hand is “ S. interrupta Vis. Almissa a rupes ”. It is possible this specimen was collected before 1842 (when Visiani classified it as the new form S. tenuifolia “ capillaris ”) and that he himself re-classified this same specimen subsequently to his description of S. interrupta . Visiani never published the name " capillaris ", therefore there is not any link between this name and S. interrupta . On the basis of the name, however, it is evident that he considered the plant morphologically similar to S. tenuifolia , but with the following differences as reported in his diagnosis in Flora Dalmatica: “ Affinis S. tenuifoliae SCHRAD. ... a qua tamen videtur differe ... Magis autem differt a S. juncifolia cum qua S. tenuifolia pluribus consociatur ...”. The second herbarium sheet (No. 324) also bears two specimens, each with its own label. The label of the specimen on the right side ( PAD 0023202) reports the following in Visiani’s hand: “ Sesleria interrupta nob . Ad rupes prope Oneum ”. The label for the specimen on the left side ( PAD 0023201) reports (not in Visiani’s hand) the script “ Sesleria 223 S. interrupta . N ° 42 ”.

The five specimens mentioned above are part of the original material and are considered syntypes. We choose the specimen PAD0023202 as lectotype of the name Sesleria interrupta Vis .
