Tamarix karakalensis var. myriantha Freyn (1903: 1062) .

Lectotype (First step: Baum, 1966, Monogr. Rev. Gen. Tamarix : 62. Second step: designated here):— TÜRKMENISTAN. “ P. Sintenis: Iter transcaspico persicum 1900–1901. Nº 467. Tamarix Karakalensis Freyn et Sint. n. sp. var. miryantha Freyn et Sint. Regio transcaspica; Aschabad; versus Besmen. 4. VI. 1900. determ. J. Freyn. ” (G-00359278!).

Notes:― Freyn (1903:1062) described T. karakalensis var. myriantha based on the Sintenis 467 collection, though it appears referenced to Sintenis 477. That seems to be a typing mistake, as the number 467 occurs in the labels of all syntypes found at G, LD, P, PR and W, even in the voucher that was personally examined by Freyn (LD-1666462). We have not found any sheet numbered Sintenis 477 from the “Iter transcaspico persicum 1900–1901” in any of the studied herbaria. As in the previous case, Baum (1966: 62) said that the holotype of this taxon to be at G, and this selection must prevail (Art. 7.9, and 7.10 of the ICN). The use of “ holotype ” has to be corrected to “ lectotype ” (Art. 9.9 of the ICN), and the selection of lectotype has to be narrowed (Art. 9.17 Ex. 12 of the ICN), as more than one voucher is kept at G, and none of them is clearly marked as holotype. The voucher G-00359278 is here selected as lectotype, as it is a complete and well preserved specimen. Any other copy of the Sintenis 467 collection must be considered as isolectotype. According to our observations, the morphological variability of the var. myriantha is completely included in that of the nominal variety. We agree with Baum (1966: 33), who synonymized the names.
