Ripe peri- carp hard and brown, compressed, seen from the side broadly ovate (Fig. 24 e); style wither- ing, not persistent. Radicle below, al- bumen lateral. This species has been identified from Bentham's description only. It is, if rightly understood, nearly related to A. indicum (Willd.) Moq. (PL V, fig. 3). Of the last-named species we have in Copen- hagen specimens collected by Rottler on the plains at Tranque- bar and thus properly identical with those seen by Willdenow. They differ in the shape of the ripe fruit. In A. indicum, the style is persistent like the rest, and placed obliquely (see Fig. 24, /), and the pericarp is obovate. As stated by Ungern-Sternberg (Versuch einer Systematik d. Tribus Salicornieae, Diss. Dorpat 1866, p. 70), the pericarp is easily Assuring in the sagittal plane. Were it not for these differences, the two species would seem to be identical. A study of a larger material, however, might per- haps reveal other differences. Port Hedland (No. 1144 bis, 3.
