Ophrys, Linn. Ophrya is the Greek appellation for 
eyebrows, and is said to be applied to this genus 
because of the fringe of the inner sepals. Linn. 20, 
Or. 1, Nat. Or. Orchidacea. The species of this 
genus are highly curious, and worth a place in 
every collection. They thrive best in a frame in a 
mixture of loam, peat, and chalk, broken small ; 
the lights should be put on in very wet or frosty 
weather. It is advisable to have some turfy grass 
growing where they are planted, as they can only 
be increased from seeds, which are parasitic when 
young, and will lay hold of the grass when they 
first vegetate. They will ripen seed without diffi- 
culty if care be taken to rub the pollen on the 
stigma. The seeds should be sown as soon as ripe, 
and when come up sufficiently, to be transplanted 
to where they are to remain.

Compoaita. A mere herbaceous weed, growing in 
Ineadows, &c. Synonyme: 1. Apargia aulumnalia

OpC'ntIa, Tournefort. Some of the species are plen- 
tiful near Opus, a city of Locris. Linn. 12, Or. 1, 
Nat. Or. Cactacex. This is a very interesting 
genus of plants, well deserving of cultivation in 
every collection. They require to be treated like 
the Mammillariaa ; and young plants may be ob- 
tained by separating the branches at the joints, and 
allowing them to dry for a few days before sticking 
them in the soil, where they soon root. O. cochin- 
illifera is valuable on account of its rearing the 
well-known coccua cacti, or cochineal insect. Sy- 
nonymea : 1. Cactua aurantiacua. 2. C. elatior. 3. 
O. humilia. 4. O. glomeraia. 5. C. Opuntia.
