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. 



ARD1SIA RIVULARIS sp. nov. § Tinus. 



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 haud 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.
