This species is manifestly a representative of the section Akosmos and 
is strongly characterized by its conspicuously maculate leaves, in this point 
simulating some of our species of Discocalyx. 
ARDISIA RIVULARIS sp. nov. § Tinas. 
Species A. boissieri et A. salicifoliae affinis, differt foliis dis- 
tincte angustioribus. Frutex circiter 2 m altus, glaber; foliis 
coriaceis, lanceolatis ad oblanceolatis, usque ad 7 cm longis et 
10 ad 18 mm latis, utrinque angustatis, acutis, nervis incon- 
spicuis ; umbellis 2- ad 7-floris, floribus circiter 1.5 cm diametro, 
calycis lobis punctatis, margine leviter ciliatis exceptis glabris, 
antheris baud rugosis, dorso obscure glanduloso. 
A glabrous shrub about 2 m high, the branches and branchlets 
brownish, terete. Leaves numerous, rather crowded, lanceolate 
to oblanceolate, 5 to 7 cm long, 10 to 18 mm wide, subequally 
narrowed and acute at both ends, coriaceous, pale-brownish or 
subolivaceous when dry, shining, of about the same color on 
both surfaces, obscurely glandular, the midrib prominent, the 
lateral nerves very slender and obscure; petioles about 5 mm 
long. Umbels in the upper axils, rather numerous, solitary, 
2- to 7-flowered, or sometimes the peduncle bearing but a single 
flower, the peduncles 1 to 2 cm long, the pedicels usually about 
1 cm in length. Flowers pink, about 1.5 cm in diameter when 
expanded. Calyx glandular, glabrous except the slightly ciliate 
margins of the lobes, the lobes extending one-half to the base, 
ovate, rounded, about 1.5 mm long. Corolla-lobes elliptic, acute, 
glandular, about 7 mm long and 4 mm wide. Anthers 4.5 mm 
long, not rugose, obscurely glandular on the back, acute or acum- 
inate. Fruits globose, 5 to 6 mm in diameter.

This species, judging from the debris attached to the specimens, and 
its narrow leaves grows on river banks subject to sudden inundation, 
having the stenophyllous leaves characteristic of a number of totally un- 
related species that grow in similar habitats. Its alliance is manifestly with 
Ardisia boissieri A. DC. and A. salicifolia A. DC., but it seems to be 
sufficiently distinct from both.
