Lubbock: On Buds and Stipules (1899)
p. 188, Rosa persica: "The stem is prickly, and the frequent occurrence of the prickles, sometimes in pairs, at the base of the leaf has led to their description as stipules; for instance, by Boissier in his great ‘Flora Orientalis’."

Meehan: Stipules as Petals (1887)

Smith: Begonia phyllomaniaca (1919)
This Begonia has been received from the Berlin Botanic Garden under the name of B. prolifera, and, as is too much the case with horticulturists, without any authority for the name attached to it, or any notice of the country whence it has been derived; and in the present state of the very difficult genus Begonia, with the several changes that it has undergone, first by the late Dr. Klotzsch, and more recently by M. Alphonse De Candolle, it would seem a hopeless task to endeavour to ascertain if it is anywhere described.
