REMARKS

Nyman’s concept (1879) of S. rosmarinifolia was based on the specimens gathered by Welwitsch and Bourgeau: “ Santolina rosmarinifolia L. – Exc. Welw. Lusit. 110. cont. 186. Bourg. Hisp. a. 1851. 2356. etc.- 1863. 2538. 2539 ( var. glaucescens ). Lusit. Hisp. (praec. centr., mer.)”. The specimens from “ Sierra Nevada , région chaude, près Guejar de la Sierra , 27.VI.1851, Bourgeau 2356 ” (COI 00035970, G, LIV 1974.38.88718, MANCH, MPU, P [4 sheets]) are S. canescens . Conversely, the specimens gathered by Welwitsch, and labelled with the numbers 110 (BM 000909648, G-BURNAT, G [2 sheets], HAL 103776, HEID, L 0653134, MPU, P [3 sheets]) and 186 (G, P) are S. rosmarinifolia subsp. arrabidensis . The specimens from “ Bords de la rivière à Gerte près Placencia, 14.VI.1863, Bourgeau 2538 ” are S. rosmarinifolia subsp. rosmarinifolia (G [3 sheets]), and S. x oblongifolia . (G, MANCH, MPU, P [3 sheets]). The specimens from “ Hauts de rivière de la vallée de Gerte près Placencia, 17.VI.1863, Bourgeau 2539 ” are S. rosmarinifolia subsp. rosmarinifolia (G [4 sheets], JE [2 sheets], MA 126712, MANCH, MPU, P [4 sheets], W), S. rosmarinifolia subsp. castellana (COI 0035990, MPU, W [2 sheets]), and S. x oblongifolia . (G). The specimen (A 00251703) from “ près Placencia, Bourgeau 2539 ” is S. rosmarinifolia subsp. rosmarinifolia . There is another specimen with this number, without locality, in P (S. x oblongifolia ). This indicates that Nyman had a broad concept of the S. rosmarinifolia name.

Two specimens of S. rosmarinifolia , gathered by Lacaita in Val Amblés (Ávila) are labelled as “ Santolina rosmarinifolia L. forma candidior foliis minute serrulatis ” (BM 000909685) and “ Santolina rosmarinifolia L. forma foliis integris atroviridibus ” (BM 00090967). Furthermore, the specimens BM 000909673 and COI 00035990 gathered by Lacaita ( Granada, Sierra Elvira ) and Bourgeau (Hauts de rivière de la vallée de Gerte près Placencia) are labelled as “ Santolina canescens Lag. forma fl. pallior citrinis ” and “ S. rosmarinifolia L. α vulgaris Boiss. forma glaucescens , glaberrima ”, respectively. These names have been rejected under Article 23 of the ICBN ( McNeill et al. 2012).
