A supposed Mexican plant, having some affinity with P. d7- 
flora, but the filamentous crown is very different, and the petals 
and sepals are nearly uniform, and to P. Mewvicana, Juss., but 
there the leaves are different, the flowers are much smaller, and 
there are no petals. At first sight it would seem to belong to 
the section “Cicca,” of De Candolle, where the perianth has only 
five lobes, or, in other words, where the petals are wanting ; but 
petals do exist here, although they are so small and so covered 
by the exterior ray of copious filaments, that they are not easily 
seen. It flowers in the stove in November, trained against the 
rafters of the house. 
Descr. A graceful climber, with slender, attenuated branches. 
Leaves \unate, that is, they are half- 
by a broad sinus above into two broad, acute, erecto-patent lobes, _ 
with a mucro in the sinus. ‘There are three primary Nerves, 
reaching, two of them to the apex of the lobes, and the central 
one terminating in the mucro of the sinus ; between the central 
and lateral nerves is a row of conspicuous, orbicular, pellucid 
glands, most apparent on the underside. Petioles much shorter
