Tamarix karakalensis var. scoparia 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 646 b. Tamarix Karakalensis Freyn et Sint. n. sp. var. scoparia Freyn et Sint. Regio transcaspica; Aschabad; Suluklü (Saratowka); ad fines Persiae: inter Mergen Ulja et Kalkulap [sic, for Kulkulab]. 20. VII. 1900. determ. J. Freyn. ” (G-00359282!).

Notes:― Tamarix karakalensis var. scoparia was described based on the Sintenis 646b collection ( Freyn, 1903: 1062). Baum (1966: 62) reported that the holotype was kept at G. As it was explained in the case of T. askabadensis , Baum’s typification must prevail (Artt. 7.9, and 7.10 of the ICN), but the use of the term “ holotype ” has to be corrected to “ lectotype ” (Art. 9.9 of the ICN). However, two vouchers of Sintenis 646b are kept at G, and some additional ones are known to be conserved at LD, P and W, they all being syntypes (Art. 9.5 of the ICN). Hence the selection of lectotype has to be narrowed to one of the specimens at G (Art. 9.17 of the ICN), since none of them is clearly marked as holotype. Therefore, the voucher G00359282 is here selected as lectotype, since it is well conserved. Any other copy of Sintenis 646b must be considered as isolectotype. In our opinion the phenotypic variability of the nominal variety completely includes that of var. scoparia . We agree with Baum (1966: 33) in synonymizing the names.
