Tamarix askabadensis Freyn (1903: 1059) .

Lectotype (First step: Baum, 1966, Monogr. Rev. Gen. Tamarix : 33. Second step: designated here):— TÜRKMENISTAN. “P. SINTENIS: Iter transcaspico-persicum 1900–1901. Nº 295. Tamarix askabadensis Freyn et Sint. n. sp. Regio transcaspica; Aschabad: prope Koosen. 19. V. 1900. determ. J. Freyn ” (G-00359261!).

Notes:― Tamarix askabadensis was described on the basis of the collection Sintenis 295, from “ Askabad, pr. Kösen ad ripas et loca humida subsalsa, 19.V.1900, in Blüthenfülle ”. Vouchers belonging to Sintenis 295 were found at G, JE and LD, which are to be regarded as syntypes (Art. 9.5 Ex.3 of the ICN). Regarding the two copies kept at LD, one of them (barcode 1210404) bears a label handwritten by Sintenis and later by Freyn, indicating that Freyn studied that voucher on April 15 th 1902. All other copies from that exsiccata bear typewritten labels that were printed before the distribution of the specimens. Therefore, the cited specimen at LD would have been the most appropriate choice for lectotypification, as it was directly examined by Freyn. However, Baum (1966: 33) indicated that the holotype was kept at G, and also mentioned the existence of isotypes at G, P, W and WU. Following the ICN (Art. 9.9), the use of term “ holotype ” by Baum (1966: 33) should be corrected to “ lectotype ”. Once the correction is done, it has to be considered as a valid lectotypification (Art. 7.9, and 7.10 of the ICN), though Baum’s selection has to be narrowed to one of the specimens held at G. The specimen labelled as G00359261 is here selected as a second step lectotype (Art. 9.17 Ex. 12 of the ICN), and consequently any other copies of Sintenis 295 must be considered as isolectotypes. According to Baum (1966: 31), T. askabadensis is currently regarded as a synonym of T. arceuthoides Bunge , a synonymization which is supported by our own observations.
