Sect. 1. Eudryandra, Meissn.—Outer integuments of the inner faces of the two seeds united in a bifid plate separating from them. Involucres various.
See below, the observations under Sect. 2.
Series 1. Armatæ.—Flower-heads usually large, mostly terminal, enclosed in floral leaves longer than the flowers. Involucres broad. Perianths above 1 in. long. Stigmatic end of the style slender, often scarcely distinct. Leaves with prickly teeth or lobes.
This series differs from the Formosæ chiefly in the foliage.
1. D. quercifolia, Meissn. in DC. Prod. xiv. 467. Branches stout, tomentose or villous. Leaves obovate-oblong or oblong-cuneate, undulate and deeply prickly-toothed or lobed, contracted into a short petiole, 3 to 4 in. long, flat, very rigid, veined and reticulate underneath but quite glabrous. Flower-heads terminal, very large, surrounded by floral leaves longer than the flowers. Involucre hemispherical or nearly globular, nearly 2 in. long, densely villous, the outer bracts subulate-acuminate, the inner ones linear or linear-lanceolate. Perianth about as long as the involucre, hoary-tomentose above the short glabrous base, the remainder silky-villous, the limb narrow, 3 lines long. Style longer the perianth, the stigmatic end long slender and furrowed. Capsule obovate-falcate, fully ½ in. broad.—F. Muell. Fragm. vii. 50.

2. D. præmorsa, Meissn. in Pl. Preiss. ii. 265, and in DC. Prod. xiv. 467. Branches tomentose and sometimes hispid with spreading hards. Leaves obovate or oblong-cuneate, truncate, undulate, coarsely prickly-toothed or lobed, 1½ to 3 in. long, white underneath, with prominent transverse veins. Flower-heads terminal, surrounded by floral leaves at least as long as the flowers. Involucre broad, the outer bracts broadly lanceolate and tomentose, the inner ones narrow and acute, about half as long as the flowers. Perianth above 1 in. long, silky-villous, the limb 2 lines long, villous with longer hairs than those of the tube. Style longer than the perianth, with a distinctly sulcate stigmatic end of about 1 line. Capsule obovate-falcate, rather above ½ in. long.

3. D. cuneata, R.Br. in Trans. Linn. Soc. x. 212, Prod. 397. A tall shrub, the branches rather thick, tomentose and often hispid with long spreading hairs. Leaves shortly petiolate, from obovate to oblong-
