he beautiful Aévides Lawrenceae, one of the finest species of the genus, 
| is a native of the Philippine Islands, whence it was introduced, in 1883, 
through their collector R6seE.in. Its habitat is said to be in south-east 
Mindanao, where it is abundant, especially, around Duvao, growing on trees in 
light shade, or sometimes quite exposed. It is said to be often associated with 
Vanda Sanderiana and Phalaenopsis Sanderiana, in some cases even growing on the 
same tree. Aérides Roebelinii also grows in the same district, if not actually inter- 
mixed with it. 
It is allied to A. odoratum Lour., though a much finer plant in every 
respect, with larger flowers, differently shaped side-lobes to the lip, and a longer 
spur. It was described by Reicuenpacu, who dedicated it to Lady Lawrence, 
wife of Sir Trevor Lawrence, Bart., President of the Royal Horticultural Society. 
It is stated in the original description that a plant of it was secured by Sir Trevor 
LawrENCE at Stevens’ Rooms, after a spirited competition, for the sum of two- 
hundred and thirty-five guineas, then one of the highest prices ever paid for an 
Orchid. 
A plant subsequently described as A. Sanderianwm Rcus., was imported 
at the same time, and from the same locality, and is certainly nothing more than 
a variety of A. Lawrenceae with a little more yellow in the ground colour of the 
flowers. The leaves are also said to be a little narrower, but it is uncertain if 
this character can be relied on. The variety Amesianum is a later introduction, 
which is said to have rather shorter and more rigid leaves. It is therefore clear 
that the species is somewhat variable, as was only to be expected. 
Aérides Lawrenceae is a robust plant, with gracefully recurved leaves from
