austinii Sull. (syn. S. imbricatum Hornsch.
ex Russow subsp. austinii (Sull.)
Flatberg) – Paton
1969a: 708 recorded that a letter from Curnow to Holt dated
1883 (DGS) states
that S. austinii and S. laricinum (= S. contortum) from
Stabler and MacAndrew were 'planted in our moors'. There is no
evidence that either species survived in Cornwall].
