Linpenra rivalis. Benth. Pl. Hartweg. p.84. Hook. Ic. Pl. v. 6. t. 476. Lin- 
den, Hort. Lind. 
A very handsome Rubiaceous genus, established by Mr. 
Bentham in his ‘ Plantae Hartwegianz,’ on specimens first, we 
believe, collected by Mr. Linden in Southern Mexico, on the 
banks of the Teapa (Herb. du Sud, n. 331), and by Mr. Hartweg 
on the banks of streams; La Vera Paz, Guatemala, Hartweg, 
n. 581. It was first figured by us in the ‘Icones Plantarum,’ 
above quoted; since by Mr. Linden in ‘ Hortus Lindenianus,’ 
and in the ‘ Flore des Serres,’ as above quoted.’ The author com- 
pares the genus to that of the Brazilian Adugustea, but differing 
in the form of the corolla, of which the tube is long, slender, 
and straight, as in Zocoyena, without the inflated throat of Au- 
gustea ; the style is also perfectly smooth. ne 
It is a handsome evergreen shrub, with leaves clustered, as it 
were, at the apices of the branches, and an imperfect corymb of 
remarkably long tubular flowers, which are, in our stove at Kew, 
in perfection in May, and have the merit of continumg some 
JuLy lst, 1861.
