Comparative wood anatomy of Taxaceae

Australian Systematic Botany, 2015
Comparative wood anatomy of Taxaceae s.l. was examined to elucidate the differences in wood features among genera.

Ultrastructural features of megasporogenesis inTorreya nucifera (Taxaceae)

Plant Systematics and Evolution, 1996
In megasporogenesis ofTorreya nucifera (Taxaceae) more than one product of meiosis can start to germinate, a process previously observed inTaxus. Ultrastructural analysis ofT. nucifera revealed that this behaviour is cytologically determined by the presence of a transfer cell type wall-membrane apparatus and by the presence of uncommonly complex ...

RNAseq‐based phylogenetic reconstruction of Taxaceae and Cephalotaxaceae

The position of Amentotaxus and Torreya is also ambiguous. Some authors consider them closer to Taxaceae while others deemed them to fit within Cephalotaxaceae.
