Rhododendron x alterclerense ‘Thyrsiflora’

Probably a cultivar of Rhododendron x alterclerense Lindl. Listed in the 1836 edition of Loddiges’ Nursery catalogue as Azalea hybridae altaclerensae thyrsiflora under Hardy Trees & Shrubs.  I have found no description of this azalea.

History at Camden Park

Desideratum to Loddiges’ Nursery on 16th April 1846 [MP A2933-1, p.147].  I have found no other record of this plant and it may not have been received.  But Macarthur had mixed fortunes with plants received from Loddiges’ and elsewhere at this time and many were dead on arrival.  Some of these are listed in a subsequent letter but it is possible that others arrived alive and were planted in the gardens although never listed in the catalogues.
