BULBIFERUM Makino, 1891

Synonym : Sedum alfredii var. bulbiferum  (Makino) Fröderström (1931)

 

Distribution : Japan (Honshu, Shikoku, Iheya, Okinawa, Kyushu), Taiwan (Nantou), Korea, south-eastern China; shaded places, lowlands, to 1000 m.

 

 

Description (according to IHSP, 2003) :

 

Annual or perennial herbs with erect or ascending stems, often branched from the base, producing bulbils in the axils of the leaves and bracts, bulbils consisting of 1 - 3 pairs of small fleshy scale-like leaves.

 

Leaves alternate, opposite at the stem base, ovate-spatulate to spatulate-oblanceolate or oblong, obtuse, sometimes mamillate towards the tip, spurred, 4 - 20 x 2 - 10 mm.

 

Inflorescences : Flowering branches often branched, to 20 cm tall, inflorescences cymes with 1 - 3 cincinni, these often forked, bracts leaf-like.

 

FIowers 5-merous, subsessile, sepals basally free, shortly spurred, unequal, broadly lanceolate to oblanceolate, (sub-) obtuse, mamillate, sometimes recurved at the tip, 2 - 6 x 0,5 - 2 mm, petals free, lanceolate, shortly and narrowly mucronate, yellow, 3,5 - 5 mm, anthers orange-yellow.

 

Cytology: 2n = 38, ±56

 

Ohwi (1965) included S. subtile var. obovatum [see S. makinoi] in the synonymy here, whereas Makino (1914) treats it as a separate species, S. obovatum. The recently de-scribed S. jinianum is very similar.
