Content
Description
Trees or shrubs.
Stipules adnate to or free from the petiole.
Flowers terminal, solitary, bisexual.
Ovules generally 2 in each carpel, rarely 3 or 4 in the lower carpels, in few species up to 4 or 5 in all carpels.
Fruiting carpels free, crowded, dehiscent along the dorsal suture, in subg. Talauma the basal parts of the ripe carpels staying adnate to the torus, the apical parts falling and thus exposing the seeds which hang from the lengthened funiculus, sometimes the apical parts during or before falling dorsally dehiscing;
Distribution
Asia-Temperate: Taiwan (Taiwan present), Asia-Tropical, Himalayas present, Japan present, New World present, S. Brazil present, SE. North America present, temperate and tropical SE. Asia present
About 120 spp. of which about one third in the New World from SE. North America to S. Brazil, the remainder in temperate and tropical SE. Asia from the Himalayas to China, Japan, Taiwan and Malesia. In Malesia represented by sect. Maingola of subg. Magnolia, and sect. Blumiana and sect. Aromadendron of subg. Talauma.
Notes
Two species of subg. Magnolia are commonly cultivated in Malesia, M. coco (LOUR.) DC. and M. grandiflora L. Magnolia coco (of sect. Gwillimia) differs from the species in sect. Maingola because the stipules are adnate to the petiole. The species can be distinguished from sect. Blumiana, especially from M. can-dollii, by the midrib being not prominent on the uppersurface. Magnolia grandiflora (of sect. Theorodori) has petals of 7 cm long or even longer while those in sect. Maingola never exceed 5 cm. The stamens in M. grandiflora are 2-3 cm long and the densely appressedly pubescent brachyblast 8 mm diam. or more.
