Pteris × siamica: a Novel Hybrid between Pteris cretica 'Albo-lineata' and Pteris multifida 'Crestata'
Pteris is one of the horticultural important fern genera. Its silvery mid-frond in some species makes the fern outstanding for indoor decoration. Recently, a crested frond form was discovered in some plain-green frond species. It was thus desirable if a crested frond trait could be combined with silvery mid-frond trait. An attempt to create an interspecific hybrid between Pteris cretica Albo-lineata and Pteris multifida Crestata was successfully executed. The hybrid uniformly had crested fronds, indicating the non-recessive control of the trait. It also clearly exhibited intermediate characteristics between the two parental species, including the degree of frond crestation and the mid-frond color. For the mid-frond area, the hybrid had light green color but with wider area than Pteris cretica Albo-lineata.
