Sh. Shi et al., PHYLOGENY OF THE HAMAMELIDACEAE BASED ON THE ITS SEQUENCES OF NUCLEARRIBOSOMAL DNA, Biochemical systematics and ecology, 26(1), 1998, pp. 55-69
The phylogeny of Hamamelidaceae was constructed based on sequences of
the internal transcribed spacers (ITS) and the 5.8S coding region of n
uclear ribosomal DNA. The monophyly of both the Altingioideae and the
Hamamelidoideae was strongly supported. The tribe Kamamelideae was, ho
wever, shown to be polyphyletic. Loropetalurn of the tribe Hamamelidea
e formed a monophyletic group with Corylopsis of the tribe Coryopsidea
e. Hamamelis of the tribe Hamamelideae was closely related to Distyliu
m, Fothergilla and Shaniodennl on of the tribe Fothergilleae. The ITS
data supported Endress' treatment of merging the tribes Distylieae and
Fothergilleae. Fortuneal ia of the tribe Eustigmateae was phylogeneti
cally basal to the Hamamelis-Fothergilleae monophyletic group. The sub
family AItingioideae was cladistically basal within Hamamelidaceae. Li
quidambar of the Altingioideae was paraphyletic and Altingia and Semil
iquidambar formed a sister group relationship. Disanthus was highly di
vergent from other taxa and its subfamiliaI status was supported. (C)
