216 THE CACTACEAE. 
Schumann cited Lepismium mittleri as a synonym of Rhipsalis squamulosa, referring 
it to Forster (Handb. Cact. 455. 1846), but the plant is there described as Rhipsalis mittlert. 
Cereus elegans Hortus appeared first (Pfeiffer, Enum. Cact. 138. 1837) as a synonym 
of Lepismium commune, while the Index Kewensis refers it to Rhipsalis muttlert. 
Cereus myosurus tenuior Salm-Dyck (Hort. Dyck. 65. 1834) is only a name. 
Lepismium cavernosum minus Lindberg is a name mentioned. by Roland-Gosselin 
(Rev. Hort. 70: 108. 1899). 
Lepismium dupret, the name mentioned by Salm-Dyck (Cact. Hort. Dyck. 1844. 41. 
1845) and by Forster (Handb. Cact. 456. 1846) as in the collections at Paris, was never 
described. 
Lepismium laevigatum Salm-Dyck (Cact. Hort. Dyck. 1844. 41. 1845) is without 
description, nor do we find it listed in the Index Kewensis.

Unarmed, slender, branched cacti; branches terete, short, arising in 2’s or 3’s from tops of 
older ones, smooth, leafless and spineless,* bearing several small areoles along their sides and each 
a large, woolly, terminal one from which the flower and succeeding ‘branches arise; sepals usually 
im 2 series, outer ones broader and short, inner ones larger and more petal-like; petals distinct, 
narrowed toward base; stamens distinct, erect, borne on disk; stigma-lobes 4 or 5, erect or a little 
spreading, white; ovary globular, naked or nearly so. - 
Type species: Rhipsalis salicornioides Haworth. 
Some six or seven species have been described ; we recognize three. 
The genus Hariota was named for Thomas Hariot, a botanist of the 16th century, 
ora being an anagram. It is closely related to Rhipsalis, with which it is often united. 
The flowers open only in bright sunlight and are rotate or nearly so. In the United 
States the plants flower under glass, usually in the winter from December to February, 
but sometimes as late as April |
