In the specimens sent to Rohrbach by Boissier himself as authentic, 
the capsule is found sometimes to be twice the length of the carpophore 
(as under the name of S. damascena), at another time nearly equal to it, 
so that in this character it cannot be distinguished from 8S. siderophila, 
Boiss. et Gaill., and as S. damascena can only be considered as a variety 
of S. palestina, S. siderophila is reduced to a synonym. In FI. Orient., 
suppl., p. 94, Boissier coincides with this view of the species—‘ Huic 
speciei S. damascenam et S. siderophilam ut varietates cl. Rohrbach con- 
jungit quod ulterioribus observationibus mihi comprobandum esse videtur.”’ 
Geogr. limits—N. Mt. Lebanon (var. damascena).

Rohrb., Monogr., p. 104. 
Differt a S. villosé floribus sub anthesi breviter nec calyci 
sequilonge pedicellatis, calycis brevioris dentibus elongatis 
obtusis, petalorum lobis linearibus, capsuld ovata, seminum 
duplo majorum forma diversissima. 
As Rohrbach points out, Boissier in Fl. Orient., i. p. 593, misquotes 
himself in citing S. affinis as a MS. name. The reason, however, why 
he re-named the plant S. arabica was his recognition of S. affinis, Godr., 
as a good species (‘ Fl. Juven.,’ ed. I. p. 9), which latter Rohrbach shows 
is in no way to be distinguished from S. micropetala, so that Boissier’s s 
first name is one to be restored, which Rohrbach has done.
