Title
Systematic implications of pinna venation and pinna anatomy in Zamiaceae
Tang Yuan Acta Phytotaxonomica Sinica 2004
Other claims from this paper (19)
- Observation Zamiaceae pinna venation has dichotomous parallel veins without a midrib.
- Observation Encephalartos friderici_guilielmii vein endings connect in different forms.
- Observation Macrozamia moorei vein endings connect in different forms.
- Observation Lepidozamia peroffskyana vein endings are unconnected and reach the pinna margin.
- Observation Ceratozamia mexicana var. robusta vein endings are unconnected and reach the margin; girder sclerenchyma connects only to the abaxial epidermis.
- Observation C. hildae vein endings are unconnected and reach the margin; girder sclerenchyma connects only to the abaxial epidermis.
- Observation Zamia muricata has unconnected vein endings reaching the margin and girder sclerenchyma connected to both epidermises.
- Observation Z. debilis has unconnected vein endings reaching the margin and girder sclerenchyma connected to both epidermises.
- Observation Z. furfuracea has unconnected vein endings reaching the margin and girder sclerenchyma connected to both epidermises.
- Observation Z. floridana has unconnected vein endings reaching the margin and girder sclerenchyma connected to both epidermises.
- Observation Vein endings gradually fade out in L. peroffskyana.
- Observation Vein endings gradually fade out in C. mexicana var. robusta.
- Observation Vein endings gradually fade out in C. hildae.
- Observation Zamiaceae pinnae generally contain adaxial and abaxial epidermises, hypodermal sclerenchyma and variably differentiated mesophyll; typical spongy parenchyma and transfusion tissue are absent.
- Observation D. spinulosum mucilage canals lie opposite vascular bundles.
- Observation E. friderici_guilielmii mucilage canals alternate with vascular bundles.
- Observation L. peroffskyana mucilage canals alternate with vascular bundles.
- Observation M. moorei mucilage canals alternate with vascular bundles.
- Observation Pinna anatomy and venation support Stevenson's division of Zamiaceae into two subfamilies.
