is fertilised ; they are often so deceived as to lay their eggs on the 
spadix.

gamic firs, below, which give subterranean fruits like Arachis.

Anacampseros. Portulacaceae. 9 sp. S. Afr. Xerophytes with fleshy 
leaves ; stipules represented by bundles of hairs protecting the young 
leaves in the bud. 
Anacamptis Rich. = Orchis Linn. 
Ana^ardiaceae. Dicotyledons (Archichl. Sapindales). 59 gen. with 
500 sp., chiefly found in the tropics, but occurring also in the 
Medit., Chino-Jap., N. Amer., and Andine regions. In habit they 
resemble plants of other families, e.g. Rutaceae, Leguminosae, Sa- 
pindaceae, &c., but their floral characters mark them off as a distinct 
order. They are trees or shrubs with alt. exstip. leaves and 
panicles of firs. Resin-passages occur, but the leaves are not 
gland-dotted (hence they cannot be confounded with Rutaceae). 
The receptacle may be convex, flat or concave, and a gynophore 
or other axial outgrowth may occur. The flr. is typically 5-merous, 
but usually with reduction in the essential organs. The sta. are 
generally less than 10, the cpls. most commonly 3, rarely (3). 
Very often only one of the three is fertile, and frequently only one 
cpl. is found at all. Ovule solitary, anatropous with dorsal raphe. 
Fruit various. Endosperm. [Placed in Sapindales by B.-H.] 
Classification and chief genera (after Engler) : 
A. 5 free cpls. or 1. Leaf simple, entire: 
I. MANGIFEREAEi Mangifera, Anacardium. 
B. Cpls. united. Lf. rarely simple: 
II. SPONDIEAE (ovules in each cpl.) : Spondias. 
III. RHOIDEAE (one ovule only, ovary free): Pistacia, 
Rhus.

C. Cpl. 1. ? flr. naked. Lf. simple, toothed: 
V. DOBINEEAE : Dobinea (only genus).
