1. Cymbocarpa refracta, Tas. XXXVIII. fig. 4. 
Native of the Corcovado Mountain, near Rio de Janeiro. 
This plant resembles Dictyostega very much in habit, but the singular form 
of the stigma and the remarkable dehiscence of the capsule sufficiently distin- 
guish it. It grows to the height of from three to six inches, and is altogether 
white with a yellowish hue: it has delicate fibres branching from a simple 
root: the stem is generally simple, very slender, erect, often flexuose, some- 
times even tortuose. The bracteiform leaves are erect and free, rather acute, 
and very small. The stem is terminated by a pair of few-flowered racemes, 
each generally with from three to six flowers upon short pedicels, with a 
single small bracte on its summit, where the flower is suddenly bent back at a 
right angle. The tubular perianthium above the portion investing the oval- 
shaped ovarium is very short, and gradually contracted a little below the 
mouth, where it again expands, and its border is divided into six unequal 
segments, the three erect acute sepals being alternate with the three shorter 
petals, which are of an oval form, and somewhat concave, miore interior, and 
fixed by a short claw in the rounded spaces intervening between the sepals. 
The stamens resemble those of Dictyostega in all respects. The ovarium is 
oblong, rounded, slightly conical at its summit, where it is free from the 
perianthium, and from it rises an erect, slender, short style; the stigmata, each 
with two long subulate erect horns, according to the description given in the 
generie character, are of a whitish colour; they nearly fill the mouth of the 
tube, and are contiguous to the stamens. The somewhat trigonous capsule, 
crowned by the persistent withered perianthium and style, bursts only on one 
of its angles in the singular manner described, displaying a great number of 
yellowish, opake, scobiform seeds, which are crowded upon the three longitu- 
dinal, horny, parietal placentæ. It was found in the Corcovado Mountain, 
close to the spot where the Dictyostega orobanchioides occurs.
