Aegle sepiaria

The Aegle sepiaria, of the order Rutaceae, was introduced from China and Japan in 1841. Here it makes a thick bush 8 feet or more high, densely clothed with very formidable spines.

The flowers are white, ornamental, and freely produced; the fruit is round and orange like. From its dense habit and spiny growth it would make an excellent hedge plant if it could be procured in quantity, especially for the southern counties.

It has many synonyms, some of which are Citrus trifolia, Limonia trifoliata, and Pseudaegle sepiaria.
