The question very naturally suggests itself, VOL. XXV. PART II. 8 F 648 DR DICKSON ON DEVELOPMENT OF have we not in Salvadora, with oppositi-sepalous stamens and solitary exalbu-minous seed,* a plant bearing the same relation to Lentibulariacese, with numerousexalbuminous seeds, as Plumbaginacese, with oppositi-petalous stamens andsolitary albuminous seed, bears to Primulacese, with numerous albuminous seeds ?I believe that in Salvadoracese with Lentibulariacese, on the one hand, andPlumbaginacese with Primulacese, on the other, we have two parallel nearlyallied series. I shall not, however, pursue this subject further, as my personalknowledge of Salvador a is very Diagram of the flower of Pinguicula vulgaris, L., showing the aestivation of calyx and corolla, the stamens andstaminodes superposed to the anterior and lateral sepals, and the one-celled ovary with free central wall of the ovary is represented as divided into five parts by two plain and three dotted lines, the twoplain lines representing the division of the stigma into two lips or of the capsule into two valves, the threedotted lines representing the abnormal fissures in the above mentioned monstrosities. * Wight (Icones pi. Ind. Orient, t. 1621), Endlicher (Genera, p. 349), Lindley ( p. 652), and Payer (Lecons, p. 14) agree in describing Salvadora as having a unilocularovary with solitary erect ovule. Professor Oliver has kindly examined for me flowers of S. persica,L., and S. Wightiana, PL, from the Kew Herbarium, of which he reports in a letter as follows:— In each of these I find a 1-celled ovary with a sol
