Several species of stapelia are in the desert biome at the Franklin Park Conservatory. During winter, the plants need a cool, dry rest limit watering to just enough to keep the stems from shriveling. They need moderate watering and good drainage during summer. They should be left to callus for a week before planting. Stapelias can be propagated easily from cuttings in the spring. The buds are just as interesting - they resemble inflated balloons. The center of the flower contains black structures that resemble flies. The look of the flower and the foul odor attract pollinating flies. The flowers are leathery with reddish striations and hairs to resemble a carcass. The carrion flower ( Stapelia gigantea) has a starfish-shaped bloom measuring 10 inches to 16 inches across. The slightly fuzzy creeping stems have four sides and grow upright. The herbaceous succulents are part of the milkweed family and closely related to the common milkweed, ceropegia and hoya. Corrections to phenology list of April 9, 1991.The carrion flower is part of the Stapelia genus, which includes 100 species.

All other species of Smilax are woody perennials with prickles (FNA 2002). Both species have flat flower peduncles instead of round ones. Smilax pulverulenta has leaf blades with dark green undersides covered with transparent hairs. One of a rare group of thermogenic plants, the Dead Horse Arum can raise its temperature by thermogenesis. It reproduces the stench of rotting meat, attracting carrion-seeking blowflies which act as pollinators. Their leaf margins are convex instead of concave and the flower petals are larger, 3.5-5 mm. Helicodiceros muscivorus (Dead horse arum lily) is an ornamental plant, native to the northwestern Mediterranean region. Smilax herbacea and Smilax pulverulenta are the other two herbaceous species of Smilax lacking prickles. This vine can be identified vegetatively with leaf characters but is best seen in flower and/or fruit. Best Life Stage for Proper Identification Characteristics needed to ID: stem with leaves and fruit or flowers. Best life stage for ID: in fruit or flower. Identifying Characteristicsĭistinguishing characteristics: stems herbaceous, annual, unarmed upper bracts at base of stem gradually changing to foliage leaves, the lowest leaves distinctly smaller and narrower than those above fully developed leaves green on both sides, more or less deltoid-ovate or panduriform, the blade with 3 prominent nerves running into the abruptly bent or twisted tip leaf margins straight or concave pedicels 3-10 (-15) mm long, arising from the axis of foliage leaves tendrils present tepals 1.5-2.5 mm long filaments shorter than to about equaling anthers styles slenderly clavate berries blue to black, with sweet and date-like pulp. The berries are blue to black with a white waxy covering and 4-6 mm in diameter (FNA 2002). The round flower cluster at the top of the peduncle contains 10-30 green flowers with tiny sepals and petals both 1.5-2.5 mm long. The two or three long flower peduncles arise from the base of the leaf and are longer than the leaf petioles and sometimes about as long as the leaf.

The larger ones have wider rounded bases with concave sides and are slightly heart-shaped at the petiole. The fingers can range from purple to green, with unhealthy plants yellowing when under stress. Each plant is a conglomeration of multiple spineless fleshy ‘fingers’ approximately 10cm high with coarse nodules up multiple sides. Individual plants can cover a small area under a shrub or up to 5m2. The leaf blades are 5-12 cm long, thin and hairless, green above and whitish below. Carrion flower is a low lying ground cover succulent. There are many leaves along the stem and most of them have tendrils at the base that help the plant climb. Identification Comments General Descriptionįalse China-Root is an herbaceous, annual vine that reaches up to 2 meters in height by climbing on the surrounding vegetation.
