Page "Lavender" Paragraph 6

One of the first modern major classifications was that of Dorothy Chaytor in 1937 at Kew.

The six sections she proposed for 28 species still left many intermediates that could not easily be assigned.

Her sections included Stoechas, Spica, Subnudae, Pterostoechas, Chaetostachys and Dentatae.

However all the major cultivated and commercial forms resided in the Stoechas and Spica sections.

There were four species within Stoechas ( Lavandula stoechas, L. dentata, L. viridis and L. pedunculata ) while Spica had three ( L. officinalis ( now L. angustifolia ), L. latifolia and L. lanata ).

She believed that the garden varieties were hybrids between true lavender L. angustifolia and spike lavender ( L. latifolia ).
