大叶木莲 da ye mu lian

Magnolia dandyi Gagnepain, Notul. Syst. (Paris) 8: 63. 1939; M. megaphylla (Hu & W. C. Cheng) V. S. Kumar; Manglietia megaphylla Hu & W. C. Cheng; ?M. sinoconifera F. N. Wei.

Trees, 30-50 m tall, 80-100 cm d.b.h. Branches, leaf blade abaxial surfaces, petioles, stipules, peduncles, and spathaceous bracts densely long ferruginous tomentose. Stipular scar 1/3-2/3 as long as petiole. Leaves usually 5 or 6 clustered on branch apex; petiole 2-3 cm; leaf blade obovate, 25-50 × 10-20 cm, leathery, basal ca. 2/3 narrowed, adaxially glabrous, secondary veins 20-22 on each side of midvein, reticulate veins sparse and prominent on both surfaces when dry, base cuneate, apex acute. Brachyblasts thick and strong, 3.5-4 × ca. 1.5 cm; spathaceous bract 1, ca. 3 mm basal to tepals. Tepals 9 or 10, in 3 whorls, fleshy; tepals of outer whorl obovate-oblong, 4.5-5 × 2.5-2.8 cm, adaxially ca. 7-striated; tepals of inner 2 whorls smaller. Stamens villous, 1.2-1.5 cm; filaments flat, ca. 2 mm; connective exserted with a ca. 1 mm triangular appendage; anthers 8-10 mm, thecae distinct and ca. 1 mm wide. Gynoecium ovoid, 2-2.5 cm; carpels 60-75, ca. 1.5 cm, glabrous, with 1 furrow reaching to style apex. Fruiting brachyblasts thick and strong, 1-3 × 1-1.3 cm. Fruit ovoid to long ellipsoid, 6.5-11 cm; mature carpels 2.5-3 cm, extrorsely slightly curved, dehiscent along dorsal and ventral sutures, apex acute. Fl. Jun, fr. Sep-Dec. 2n = 38.

Evergreen broad-leaved forests; 400-1500 m. W Guangxi, SE Yunnan [Laos, Vietnam].

Manglietia admirabilis Y. W. Law & R. Z. Zhou (in Y. H. Liu, Magnolias China, 120. 2004) probably belongs here but was not validly published because no Latin description or diagnosis was provided and no type was indicated (Vienna Code, Art. 36.1 and 37.1).

The status of Manglietia sinoconifera is uncertain because the authors have been unable to see the holotype, although it may be conspecific with M. dandyi.

Manglietia dandyi is grown as an ornamental and used for timber.
