JTEW TROPICAL IFRTCAX RUBIAC'E.B 81 



Remarkable for the glabrescenee of the vegetative parts ; distin- 

 guished from R. decorticafa Hiern, its nearest ally, in the longer 

 corolla-tube, which is not glabrous, and the densely hairy calyx. 



Rutidea landolphioides, sp. nov.

 tibus, subtus in venis obscure sparse hirto-pubescentia, jyetiolo brevi 

 appresse pubescente. Li^oresceiitice alares minusculjB necnon ter-

Another ally of B. decorticafa, distinct in the very small flowers 

 with corolla-lobes longer than the short tube, in the venation, etc.

 broad, apiculate. Axillary inflorescences barely 5 cm. long. Calyx 

 barely 1 mm. in total length. Corolla-t\\bii 4 mm., lobes rather 

 longer. Anthers not quite 3 mm. 



Eutidea Talbotiorum, sp. nov. 



Nisi inflorescentia glaberrimus ; folia subcoriacea late elliptica v. 

 •ovata, brevissime acuminata, apice obtusa, basi plerumque obtusa v. 

 subrotundata ; stipulcE latissimge concavese apice rotundse, Flores in 

 cymis trira^diatis leviter rufo-sericeis dispositi. Calyx minimus ;

 more than 6 mm., lobes 5 mm. or- longer, 2 mm. broad. Anthers

Allied to R. degemensis just descril^ed, but distinct in the broader 

 leaves and shorter corolla-tube. 



Psychotria potamogetonoides, sp, nov. 



Frutex omnino glaber, ramosus, ramulis lineis 2 e cortice promin- 

 €ntibus hinc verisimiliter angulatis, foliosis. Folia lineari-lanceolata 

 V. oblonga, ad 8-9 cm. x 1'2 cm., olivaceo-nigra, utrinque leviter 

 angustata apice nisi setaceo-mucronulata obtusiuscula, basi vix petio- 

 lata, margine valde crispo-sinuata dentata apparentia, venis secundariis 

 vix conspicuis utrinque ca. 7-9 ; stipiilce deciduse parvse setoso-subu- 

 lattE crispse. Flores in cymulis parvis paucifloris 8-radiatis terminalibus 

 dispositi ; calyx subtruncatus anguste infundibularis subcostatus vix 

 1-5 mm. longus ; corollce glaberrimae tubus angustus 3-3"o mm. longus, 

 lobi lanceolati acuti patentes vix 1 mm. longi. Stamina breviter
