The name has been adopted by Linnezus in commemora- 
tion of Peter Pena, the coadjutor of De Lobel, in the wor 
entitled “Stirpium adversaria nova,” published in 1751. 
A low rigid shrub, of rather straggling growth; stem 
proliferous, prominently scarred ; branches leafy, young ones | 
glazed with a transparent gum-like varnish, which har- 
es 
dens and becomes opaque in the old. eaves decussated, 
horizontal, flat; thick, rigid, twice as long as the intervals, 
obovate, rhomboidal, broadly pointed, of an opaque green; 
stipules 4.2? minute brown, pointed, immersed in the varnish 
which covers the branch, and forming a brown ridge 
which traverses the upper face of the foot of the leaf from” 
without the sides. Flowers 2-5, terminal, aggregate, most 
commonly $ standing in the order of a quincunx, and form-_ 
ing a close oblong fascicle, enveloped by foliaceous im-_ 
bricated bractes larger than the leaves, pale green, val-~ 
nished, ciliate upwards, with a recurved point. Corolla an» 
inch or more-in length; tube obtusely quadrangular ; limb 
4-parted, cruciate, of a deep glossy rose-colour, three times _ 
shorter than the tube, obtuse. Stamens equal to the limb, 
blood-red, upright ; anthers upright, inserted at the inner 
flat front of their receptacle nearly one third above the base | 
under the cells, which are adnate, vertical, parallel, conti-. 
guous, dark brown, somewhat shorter than the plain of the 
receptacle, opening lengthways towards the stigma, against 
which they incline on parting with the pollen. 
A greenhouse plant, difficult to preserve, and not easily : 
multiplied. Cultivated ina mixture of hazel loam and peat 
mould. Introduced by Mr. Masson in 1787. 
The drawing was made in March, at the nursery of. 
Messrs. Lee and Kennedy, Hammersmith, a source from 
which we have long received a most liberal and unreserved 
supply of rare plants of the greatest use tq our botanical 
pursuits. }
