REMARKS

The lectotype shows two large flowering stems and a single sterile stem. The flowering stems are either not widened at the tip or only slightly widened.The widening observed on one of the stems appears to result from dessication or flattening of this stem. The leaves of the flowering stems are narrowly spatulate. As in the population that lives at high altitude, all the leaves of the sterile stems of the type are broadly spatulate. The capitula are very poorly preserved and the bracts were damaged during dissection by botanists. It is thus impossible to know how many external bracts were originally present. The morphological characteristics listed in Table 2 View TABLE are essential to determine hybrid characters in Santolina ’s populations, however the poorly preserved capitula did not allow a complete examination of Boissier’s original material. Therefore, it is not possible to determine if the lectotype of S. oblongifolia has hybrid characteristics or not. However, the morphological characteristics of this sample in the G-BOISS herbarium suggests that it was probably collected at an altitude below 1800 m in a mixed population including S. oblongifolia , S. rosmarinifolia subsp. rosmarinifolia and their putative hybrids. Rivas Goday (1955) considered that probably Pavon collected the original material of S. oblongifolia in locations close to Casatejada (Cáceres). Casatejada is located south of Central System, at not more than 300 m, outside the altitudinal range of this taxon. The present evaluation of the original material of S. oblongifolia suggests that the lectotype does not match with the current use of the name.
