Other claims from this paper (15)
- Observation In Cytisus scoparius, photosynthesis is restricted to ridged stems derived from stipular tissues, after leaves are shed under dry conditions.
- Observation In Genista sagittalis, stem extensions derived from leaf bases form continuous leaf-like wings down the stem.
- Observation In Leptosema aphyllum, leaf blades are reduced to brown bracts while the leaf bases form photosynthetic ridged stems or cladodes.
- Observation In L. tomentosum, leaf blades are reduced to brown bracts while the leaf bases form photosynthetic ridged stems or cladodes.
- Observation In Jacksonia alata, leaf blades are reduced to brown bracts while the leaf bases form photosynthetic ridged stems or cladodes.
- Observation Cytisus is relatively mesomorphic in anatomy and avoids water stress by losing leaves.
- Observation Genista is relatively mesomorphic in anatomy and avoids water stress by having annual stems.
- Observation Jacksonia alata has a limited photosynthetic area.
- Mechanism The limited photosynthetic area of Jacksonia alata may contribute to its subordinate position in its community.
- Observation Leptosema aphyllum has much broader cladodes and is a larger shrub.
- Observation L. tomentosum has much broader cladodes and is a larger shrub.
- Observation Stems and cladodes of Leptosema aphyllum have a dense anatomical structure and abundant sclerenchyma.
- Observation Stems and cladodes of L. tomentosum have a dense anatomical structure and abundant sclerenchyma.
- Observation Stems and cladodes of Jacksonia alata have a dense anatomical structure and abundant sclerenchyma.
- Observation Different stem and leaf structures can be modified to achieve a similar photosynthetic outcome in Fabaceae.
