Hypericum grandifolium (Nomenclature)
Shrub 0-5-1 -8(-2?) m tall, bushy, with branches erect or ascending. Stems 4-lined and ancipitous when young, soon 2-lined, eventually terete; internodes 2-4 mm long, shorter than leaves; bark scaling. Leaves sessile, ± amplexicaul; lamina (30-)40- 90 x (20-)25-45 mm, broadly triangular-ovate to oblong-ovate, obtuse (or rarely acute) to rounded, margin plane, base cordate to rounded, not paler beneath, not glaucous, papyraceous; venation: 4-5 pairs main laterals, with tertiary reticulum prominent above; laminar glands small; intramarginal glands dense. Inflorescence 1-13-flowered, from 1-2 nodes with internode not condensed, broadly pyramidal to subcorymbiform with branches widely spreading, occasionally with accessory flowers.[1], sometimes with flowering branches from up to 4 nodes below, the whole then cylindric; pedicels 5-11 mm long; bracts foliar or reduced and linear to linear-subulate. Flowers (25-)30-45 mm in diam.; buds ellipsoid-subglobose, obtuse to rounded. Sepals 6-8 x 2-3 mm, imbricate, unequal to subequal, spreading to reflexed and enlarging after anthesis, erect and persistent in fruit, lanceolate to narrowly oblong, acute to subacute, 7-9-veined from base with veins ± branched and reticulate, midrib distinct; laminar glands linear and punctiform; inframarginal glands dense. Petals golden yellow, not tinged red, spreading, (16-)18-22 x (4-)6-8 mm, 3-4 x sepals, narrowly oblong-lanceolate, with apiculus obtuse or absent. Stamen fascicles each with (25-)30-40 stamens, longest 15—20 mm long, c. 0-9 x petals. Ovary 4-5(-6) x (2-5-)3-3-5 mm, narrowly ovoid to ovoid-ellipsoid, acute; styles (rarely 5 in number) (7-5- )9.5-13(- 17) mm, 2-3 x ovary, erect, narrowly divergent towards apex, slender; stigma narrowly capitate. Capsule 8-13 x 6-8 mm, ovoid-ellipsoid to ellipsoid, acute, coriaceous, completely dehiscent. Seeds yellow- ish-brown, c. 1-2 mm long, broadly carinate or with narrow unilateral wing, almost without terminal appendages.
[1]Note: The petals in text figures appearing on pp. 298-309 are approximately natural size and the leaves half natural size
2n = 40.
In evergreen Laurus forest and on dry stony hillsides and cliffs; 200-1500 m (Canaries), 400-500 m (Madeira).
Canary Islands (all islands), Madeira.




































H. grandifolium does not show any marked geographical variation. Among the species of sect. Androsaemum with persistent sepals, it can be distinguished by its relatively lax inflorescence, relatively large flowers and completely dehiscent capsules. It has frequently been confused with H. elatum Aiton (= H. x inodorum Miller, q.v.).
