e0“one arm of the long chromosome with median constriction may translocate to the short chromosome, so that two long chromosomes with subterminal constrictions (A chromosomes of Yucca-Agave type) may result and vice versa. Such karyotype alteration may explain the relation between the Yucca-Agave type and Doryanthes type”

- Observation Five karyotype types were distinguished in Agavaceae.
- Observation Phormium and Dracaena karyotypes were similar despite differing basic numbers.
- Observation Nolina karyotypes resembled those of smaller chromosome complements.
- Observation Doryanthes had four long and forty-four short chromosomes.
- Observation Yucca-Agave karyotype was clearly distinguished from three remaining Agavaceae types.
- Observation Agavaceae karyotypes were inferred to derive from Liliaceous stock and develop toward Palmae.
- Observation Karyotype analysis postulated five phylogenetic lines.
- Observation The karyotypes showed affinity among Liliaceae, Agavaceae and Palmae.
