A new species, Manglietia pubipedunculata Q. W. Zeng & X. M. Hu (Magnoliaceae) is described and illustrated from Yunnan, China. In addition to macromorphological examination, we comparatively studied on micromorphology of leaf epidermis, leaf structure, and epidermal cell on the sclerotesta. This new species is similar to M. kwangtungensis in terms of having dense pubescence, however, their pubescence are quite different. Manglietia pubipedunculata has appressed, compressed, shorter and sparser pubescence consisting of single or two cells. Moreover, it differs from M. kwangtungensis by showing shorter and thicker peduncles, longer styles, basal carpels covered with sparsely brown appressed pubescence, and more ovules per carpel. Furthermore, the new species has thinner leaves, brown and rugged surfaces on sclerotesta, and the alveolate cell pattern consisting of pentagon or hexagon cells with papilla on secondary cell wall under the observation by SEM. The phylogenetic analysis from two nuclear PHYA and LEAFY and chloroplast trnH-psbA sequences of 11 taxa reveals that M. pubipedunculata is a distinct species. [ABSTRACT FROM AUTHOR]

Magnolia hookeri var. longirostrata D.X. Li & R.Z. Zhou, a new variety from Yunnan, China is described and illustrated. Its pollen morphology is also analyzed. It is morphologically closely allied to M. hookeri, but differs in its smaller carpels, longer and narrower gynoecia, longer and glabrous peduncles, longer fruit aggregates, and smalltuberculate follicles with longer beaks at the apex.
