Description
TABLE 2. Comparison of the vegetative and reproductive morphologies of the three series, Kalanchoe ser. Raveta, K. ser. Longiflorae, and K. ser. Rotundifoliae, recognised in K. sect. Raveta.
| # | Organ | K. ser. Raveta | K. ser. Longiflorae | K. ser. Rotundifoliae |
|---|---|---|---|---|
| A. | Vegetative | |||
| 1. | Growth form | Generally medium-sized to large, pseudo-rosulate plants with robust but often weak, leaning stems | Small to medium-sized, herbaceous shrublets with ‘hard’, erect to leaning stems | Low-growing, single-stemmed or multi-branched, herbaceous plants with thin, weak stems |
| 2. | Plant size at reproductive maturity (m) | ± 1.0(–2.5) | 0.5–1.0(–1.5), rarely>2 | ± <1 |
| 3. | Stem in cross-section | Round or vertically ridged, but hardly angled | Distinctly angled; usually 4-, 5-, or 6-angled | Round |
| 4. | Leaves (size; shape) | Large; round to obovate | Medium-sized; elliptic | Small; round to obovate |
| 5. | Leaf margins | Entire | Crenate | Entire to crenate |
| 6. | White-waxy farina | Present | Absent | Absent |
| B. | Reproductive | |||
| 7. | Inflorescence (shape in outline) | Clavate | Diffuse | Diffuse |
| 8. | Inflorescence (floral density) | Dense | Subdense | Sparse |
| 9. | Flower disposition | Omnidirectional, erect to horizontal to ± pendent | Generally erect | Erect |
| 10. | Flowers in outline | Variously elliptic | Gradually urceolate | Abruptly urceolate |
| 11. | White-waxy farina | Present | Absent | Absent |
| 12. | Corolla lobes (colour of adaxial surface) | Generally dull; whitish, to faded yellowish, to greenish, or to pinkish red | Bright yellow | Various shades of red, to orange, to yellow |
| 13. | Corolla lobes (general shape) | Broadly elliptic | Often nearly round | Lanceolate-narrowed |
| 14. | Nectar scales (shape) | Cuneiform square to transversely oblong | ± Linear | ± Linear |
| 15. | Diurnal movement (closing at night) | Absent | ± Absent | Present |
| 16. | Corolla twisting post-anthesis | Absent | Absent | Present |
| 17. | Production of plants on an inflorescence | Infrequent, but common in some species | Occasional | Infrequent, but common in some species |
| 18. | Chromosome number | 2 n = 34 | 2 n = 34 | 2 n = 34 |
