This species very much resembles P- codliza and I thought at 
first it was a variety. However, by a closer investigation the dif- 
ferences in the habit were found to be followed by differences in the 
flower, which led me to make a new species. P. collina has leaves 
with 8-10 secondary nerves and a rather dense corymbose inflo- 
rescence, while P. pseudocollina has larger leaves with 6-8 sec- 
ondary nerves anda very lax inflorescence. The calyx-lobes are quite 
distinct and rounded-acuminate in collzza, but in pseudocollina 
they are hardly to be seen. The corolla of cod/zza has lobes which 
are distinctly pilose on their upper surface, so also isthe base of the 
corolla tube, while ~seudocollina is quite glabrous with the excep- 
tion of the throat. The anthers are also much more elongated in 
our species. All these characters may be seen very well on the ex- 
cellent plate of Labillardiére Sertum Austr. ¢. 47, 1 
Our plant suggests P. turbdcnata A. Gr., but Gray’s plant has 
shorter inflorescences and its axes are hairy.

This species comes next to JZ sarmentosa Aubl., but differs not 
only in the ramification, which may vary and which is rather 
acutely angled in Aublet’s plant, but also in the form of the stipules
