Descriptions
Clematis petriei Allan
Liane with slender stems and branches climbing over shrubs and small trees, or scrambling over rocks; branchlets grooved, ± pubescent when young. Lvs with petioles up to 3 cm. long, biternately or ternately branched. Lflts (0·5)-1-3-(4) × 0·5-2-(2.5) cm., subcoriac., ovate to ovate-oblong, obtuse, entire or with 1-2, rarely more, blunt lateral lobes, especially on terminal lflt; the larger lflts sts truncate at base. Infl. of axillary, solitary fls or few-fld panicles, on pubescent-pilose peduncles up to 2 cm. long. Bracts us. small, ovate, acute, ± connate at base; sts foliaceous, narrow-lanceolate, up to 1 cm. long. ♂ c. 3·5 cm. diam.; sepals 5-8, greenish yellow, up to 2 cm. long, ovate-oblong, pubescent; stamens ∞, filaments c. 1 cm. long; anthers c. 2 mm. long, narrow-oblong. ♀ up to 3 cm. diam.; sepals up to 1·5 cm. long, ovate-oblong, greenish yellow, pubescent. Achenes ∞, ovoid, 4-5 mm. long, dark red, margins strongly thickened, glab. when mature; styles c. 3 cm. long.

Evergreen woody liane, usually climbing over shrubs and small trees; dioecious. Stems up to 2 m long, 5-6 mm diam., ribbed and sparsely hairy when young, glabrous when mature, ascending or spreading. Leaves 3- foliolate, subcoriaceous to coriaceous, green. Leaflets 10-30 × 4- 18 mm. simple to pinnate; simple leaflets broadly ovate to ovate, entire, crenate to deeply pinnatifid; pinnae linear-oblong to broadly ovate; apices of leaflets and pinnae apiculate, bases sometimes oblique, attenuate to truncate; petioles and petiolules 10-25 mm long. channelled, glabrous to sparsely hairy, twining. Inflorescences axillary; flowers solitary, or 2-6 clustered in leaf axils, or in dichasia1 cymes of 5-10; flowers unisexual, 12- 35 mm diam. Pedicels 10-40 mm long, moderately to densely hairy; bracts 6.0- 14.0 × 1.7-6.0 mm, inserted about middle of pedicel, often foliaceous, connate, spathulate, often tinged red at base, abaxial surface sparsely to moderately hairy, adaxial surface ± glabrous to sparsely hairy, apex obtuse to rounded. Male tlowers: sepals 6-8, 5.5-20.0 × 1.7-9.0 mm, narrowly elliptic, elliptic, lanceolate to ovate, yellow-green, abaxial surface with pilose to villous hairs, adaxial surface glabrous or very rarely with a few scattered hairs, apex subacute to obtuse; stamens 14-24; filaments 1.8-7.4 mm long, c. 0.75 mm wide, glabrous, linear, often gradually tapering toward distal end or slightly at both proximal and distal ends; anthers 2.0-2.3 mm long, c. 0.6 mm wide, linear- oblong, cream; receptacle 0.5-0.6 mm high, 1.0- 1.1 mm wide, ± glabrous to moderately hairy; carpelodes absent. Female flowers: sepals 6-8.6.0- 15.0 × 3.5-5.0 mm, narrowly elliptic, elliptic, lanceolate to ovate, yellow-green, abaxial surface with pilose to villous hairs, adaxial surface glabrous, apex subacute to obtuse; carpels 30-39; ovary c. 1.2 × c. 0.4 mm, glabrous; style 4.4-5.3 mm long; pappus hairs 5 4 mm long, dense, white, ascending; stigma 0.4-2.7 mm long, curved, papillate on adaxial surface, abaxial surface smooth; receptacle 2.0- 2.2 mm high, 1.0- 1.1 mm wide, moderately hairy; staminodes 6-12, in outer whorl; filaments 4.0- 4.2 mm long; anthers c. 1.0 mm long, malformed, barren. Achenes 3.5-4.4 mm long, 1.5-2.3 mm wide, 1.0- 1.2 mm thick, glabrous, chesmut-brown; style 5-17.5 mm long, pappus hairs spreading, base of style usually glabrous. FL Oct-Jan; FT Dec-Mar.
