Fuchias in the City | Fuchsia Section Ellobium
The Genus Fuchsia

Section Ellobium
(three species)

This small section consists of just three diploid species distributed in evergreen cloud forest and oak-pine forest from Jalisco, Mexico, to northern Panama as terrestrial, or epiphytic or sometimes tuberous, shrubs from 1,450 to 3,400 meters in elevation. (Breedlove et al. 1982) The leaves are opposite or ternate. The flowers are axillary, or held in racemes or panicles, with elongated floral tubes from 20 to 65 mm long. Its nectaries are smooth and unlobed. The sepals are erect to spreading and colored green to reddish green or pale red with olive-green or bright red petals. The stamens occur in two unequal series and have yellow pollen. The seeds number between fifty and two hundred. The section's breeding system is hermaphroditic.

This section's name derives from the Greek word, ellobion, or earring. It was first applied to Fuchsia fulgens (De Candolle 1828) when the Swedish botanist, author and colorful social philosopher, Niels Lilja (see Dictionary of the Fuchsia), established a new genus for it as Ellobium fulgens in 1841. Previously in 1840, he had moved Fuchsia fulgens into Spachia fulgens. Lilja was noted for his study of Swedish plants but it's unclear why he would move a plant so far outside his native habitat not once, but twice. Ellobium has been synonymous with Fuchsia, however, when Lilja was eventually corrected by Carrière in 1881. The name was revived for this section of the genus.

F. decidua  Standl.
Mexico. Rare in moist oak-pine and evergreen cloud forests in the Sierra Madre Occidental from Jalisco to Oaxaca [growing at elevations from 0,000 to 0,000 meters].

fuchsia-decidua
The flowers appear during the dry season from December to May on the previous season’s leafless branches. F. decidua is easily distinguished from the other two species in this section due its leafless dry-season flowering and tiny, thick petals.

Habit—Shrub 0.5 to 2 m high, terrestrial, in rock crevices, or epiphytic in trees as high as 10 m above the ground, with fleshy tubers 2 to 4 cm thick and stoloniferous lateral shoots. Branchlets 5 to 15 cm long, 3 to 6 mm thick, subquadrangular, glabrous; older branches 0.5 to about 3 m long, 6 to 20 mm thick, with very loosely peeling, copper brown bark.

[
F. splendens var. cordifolia]
According to Dr. Paul E. Berry, professor, director and curator at the University of Michigan's Herbarium and the world's leading scientific authority currently working on the genus, he will likely recognize two varieties as F. splendens var. splendens and splendens var. cordifolia in a future publication.
