1.Chromosome Number:
1. T. menziesii is an autotetraploid species (2n = 28).
2. T. diplomenziesii is a diploid species (2n = 14).
2.Leaf Shape:
1. In T. diplomenziesii, the cauline leaves (leaves along the stem)
are generally longer than they are wide, with a length/width
ratio of 0.83 to 1.44 (average 1.04).
2. In T. menziesii, the cauline leaves are either not or only
slightly longer than wide, with a length/width ratio of 0.57 to
1.09 (average 0.89).
3.Plantlet Formation:
1. T. diplomenziesii produces plantlets less frequently compared
to T. menziesii, which tends to form more adventitious buds at
the apex of the petioles that may develop into plantlets.
4.Stature and Rosettes:
1. T. diplomenziesii tends to be smaller in stature and has less
well-developed rosettes compared to T. menziesii.
