Tamarix karakalensis Freyn (1903: 1060) .

Lectotype (designated here):— TÜRKMENISTAN. (handwritten): “ 1966 b. Tamarix . Karakala: prope Arabadschik in valle fluvii Sumbar. 24/6. 01 ” (Sintenis’s handwritting), “ Karakalensis n. sp.! 20/4 02 Freyn ” (Freyn’s handwritting); (Typewritten): “ P. Sintenis: iter transcaspico persicum 1900–1901. Nº 1966 b. Tamarix karakalensis Freyn et Sint. n. sp. Regio transcaspica; Kisil Arwat; Karakala: in valle fluvii Sumbar. 24.VI.1901. Determ. J. Freyn ” (LD-1210584! [digital photo]).

Notes:―In the protologue of Tamarix karakalensis, Freyn (1903: 1060) mentioned two exsiccata, collected in different locations and dates: (1) “ Karakala prope Arabadschik in valle fluvii Sumbar, 24-VI-1901 (Sintenis 1966b) ” and; (2) “ Nurgeli chan ad rivum, 28-VI-1900 (Sintenis 1966a) ”. Vouchers of Sintenis 1966b collection have been found at G, LD, MO, P and W, and Baum (1966: 62) also reported isotypes at E, W and WU. Conversely, the only copy of Sintenis 1966a that we were able to trace is kept at LD, though this collection was not mentioned by Baum (1966). A lectotype is to be selected from the pull of syntypes of these two collections (Art. 9.5, 9.11, and 9.12 of the ICN). Among those vouchers belonging to Sintenis 1966b, only that one present at LD bears a handwritten label (with both Sintenis’s and Freyn’s handwritting) matching exactly the protologue, alongside with the printed label that is shared with the other copies. The “ b ” letter besides the collection number 1966 is missing in the printed labels of most of the found vouchers (P, MO and W), and it was handwritten in the others (G and LD). However, they can be easily assigned to Sintenis 1966b by matching the locality and the collection date printed in the labels. Among all the existing material, the Sintenis 1966b voucher LD1210584 is here selected as lectotype. It is the only one whose label perfectly matches the information in the protologue and it was personally examined by Freyn, since his handwriting clearly appears in the label. Any other voucher belonging to Sintenis 1966b collection, including those without “ b ” but matching the location and date, must be considered isolectotype. Any voucher belonging to Sintenis 1966a collection must be considered as syntype.

T. karakalensis was accepted as an independent species by Baum (1966: 60), though it is morphologically very similar to T. arceuthoides , as it has been recently suggested by Samadi et al. (2013: 196). Accordingly, we consider both taxa to be synonyms, T. arceuthoides having the priority.
