CLIMBING AROIDS 
816. PHILODENDRON ANDREANUM VAR. MELANOCHRYSUM. This is a small- 
leaved type that can be used in dish gardens and under glass as a handsome substitute 
for P, CORDATUM. The heart-shaped leaves are velvety, dark green, and suffused with 
brown-yellow. 
818. PHILODENDRON ASPERATUM. We have had this plant for over a decade. We 
offer material of it for the first time. The easiest description is to call it a giant P. 
SODIROI. This species is destined to become a popular tropical foliage plant, and the 
probable parent of a new line of philodendron hybrids. 
820. PHILODENDRON X CORSINIANUM. A tropical plant of great beauty. The thin, 
heart-shaped leaves are both undulated and serrated at the edges. The surface of the 
leaves is papery and crinkled. The under leaves are metallic brownish-purple. One parent 
is P, VERRUCOSUM; the other unknown, perhaps P. LACERUM. 
822. PHILODENDRON CRASSINERVIUM. We like this species. The long curving leaves 
are like Turkish scimitars. Someone should grow four of them on a totem pole. It would 
be a conversation piece! 
824. PHILODENDRON ELEGANS. Accurately named. The leaves are deeply cut to the 
mid-rib to provide numerous long graceful fingers. The effect is open and delicate. 
Under good culture the leaves will reach 2 feet in length; the round smooth trunk 2 
inches in diameter. One of the best species of the genus. 
826. PHILODENDRON HASTIFOLIUM. This importation from Europe is a durable, 
heavy textured species that promises a relatively high degree of hardiness for a tropical 
plant. 
828. PHILODENDRON HOULLETIANUM. Likewise, this species has the same possibili- 
ties. The heavy leaves are heart-shaped and leathery. 
830. PHILODENDRON MAMEI. This highly ornamental plant extends its stem hori- 
zontally. The heart-shaped leaves are parchment-like, dark green, marked with irregu- 
lar silver spots. Native to Ecuador. 
832. PHILODENDRON MARTIANUM. (P. CANNAEFOLIUM in the U. S.) P. CAN- 
NAEFOLIUM has leaves that at a glance resemble those of a Canna. The petioles are 
long and slender and the plant runs, with long internodes. To us it is not a useful species. 
P. MARTIANUM, as this plant is called in Europe, grows horizontally, and adapts itself 
nicely to a coffee table. It looks more like a well-grown Cattleya than a Canna. 
834. PHILODENDRON SAGITTIFOLIUM. We have grown this plant since 1942 and it 
has yet to leave its compact form and start to climb. The arrow-shaped leaves are 
cupped and held broadly erect on round petioles. The plant is a very light green. A 
woven mat of fibres hides the leaf bases, but not the remarkable spathes. These are 
numerous, and inflated. The round lower sections are broadly marked with a crimson 
band. This should be a sensational addition to tropical gardens. 
836. PHILODENDRON TALAMANCAE. A rare philodendron with very elongated hastate 
leaves. This is a useful, practical plant. 
838. PHILODENDRON VERRUCOSUM. This is a tropical species and is unhappy below 
65°F. The soft, heart-shaped leaves are velvety above and marked beneath with reddish- 
brown areas. The petioles are fuzzy. A native of Columbia. 
840. PHILODENDRON WARSCEWICZII. We do not guarantee this identification, but 
we do claim that it is a remarkable member of the genus. It apparently comes from an 
area that endures a long drought, when the leaves fall, and the terminal growth bluntly 
closes itself with a twist, like the ends of some Cuban cigars. Then the plant with its fat, 
round trunk (the scars from the fallen leaves scarcely show) looks like a boa-constrictor. 
When the rains come the plant bursts into leaves that resemble those of a medium- 
sized arborescent philodendron, such as P. BIPINNATIFIDUM, but much thinner in 
texture, lighter green, and more elaborately serrate. 
842. RAPHIDOPHORA DECURSIVA. One of the hardiest of the climbing aroids. The 
leaves are held in horizontal, elongated planes, divided to the midrib in broad leaflets. 
Ui general habit of the plant is that of a medium-sized Monstera. Native to North 
urma. 
844. MONSTERA GUTTIFERYUM. This species is something like a small growing M. 
KARWINSKYI, without, however, perforations in the leaves. Several planted on the 
same fern-tree pole make a nice effect. 
846. MONSTERA KARWINSKYI, Schott. This rare species grows somewhat in the 
manner of M. GUTTIFERYUM. The leaves are wider (5) inches), longer (1 foot), and 
are perforated at random with roundish holes. A collector’s item. Origin unstated. 
Received from a German botanical garden.
