few sorts not in the collection at Hackney, but we have indicated where they may be procured. There are very full collections of Crataegus in the Hammersmith Nursery, in the Fulham Nursery, in the Camberwell Arboretum, and in Mr. Donald's arboretum at Goldworth; but these collections are without a number of sorts which are contained in the arboretum at Hackney.

Those names which are applied to the same plants, both in the Arboretum Britannicum and in Messrs. Loddiges's Catalogue for 1836, are in small capitals; and those taken from the Hackney arboretum Catalogue, where there are more synonymes than one, are in italics.

In the above list, and in that which precedes it, there are one or two cases attended with some doubt, from the smallness of the plants; they being only received into the collection the last or the preceding spring, and having not yet flowered. The principal case of doubt is C. lutescens Lodd. Cat.; and we have accordingly put a point of interrogation before C. Ox. lùtea, which we consider to be its synonyme. Before those names which we consider somewhat doubtful, we have also placed points of interrogation.
