when our figure was prepared. Since then Britton and 
Rose have been able to describe, as JW. costaricensis, 
yet another species, also collected by Pittier, but on 
this occasion on the west coast of Costa Rica. Britton 
and Rose also remark that Wéittia is a strange genus, 
having stems resembling those of Epiphyllum and 
Rhipsalis, with flowers very different from those of 
either of these genera. 
Description.—Herb, with succulent, sparingly branched, elongated, flattened 
stems, which are leafy in appearance, are distantly crenate along the margin, 
exhibit a stout median rib, and attain a width of 13-13in. Flowers axillary, 
borne at the bases of the crenations, 1-1} in. long, deep purple. Calyx with a 
rather slender tube about 2 in. long, which is produced well beyond the ovary, 
and clothed at the base with a few minute scarious scales; lobes 10, 2-seriate, 
erect, petaloid, oblong and blunt at the tip, those of the outer series faintly 
keeled, of the inner series rather longer and of thinner consistence. Petals 10, 
erect, oblong, apiculate, white, rather shorter than the sepals. Stamens many, 
included, 13-14 in. long; filaments slender; anthers oblong. Style slightly 
exserted, slender, nearly 2 in. long; stigmas 4-5, nearly erect, oblong.
