Allied to the previous species, but of much more slender habit, 

 thinner and narrower leaves, smaller heads, &c.

 subobtusis, brevissime petiolatis, utrinque glaberrimis supra niten- 

 tibus, reticulo praesertim subtus prominulo e quo venis lateralibus 

 ssepe nee bene definitis, stipnlis late oblongis brevissimis breviter- 

 que acutissime 2-aristatis. Florihus in capitulis trifidis paucifloris 

 dispositis, pedunculis primariis 4-5 cm. vel longioribus, secundariis 

 1'2 cm., laevissimis striatis validiusculis, bracteis 2 primariis lan- 

 ceolatis acutis + 3'5 mm. longis carnosiusculis concaveis plus 

 minus connatis intus minute pilosis, involucelli bracteis ovatis 

 acuminatis paucis + 4 mm. x 3 mm. ; calycibus mox ex involu- 

 cello exsertis campanulatis dentibus late triangularibus subacutis

Clearly allied to Cepliaclis Jenmanii and C. haieteiLrensis just 

 described. These species, the present one and the allied C. cone- 

 phoroides Eusby, lie on the border-line between Psychotria and 

 Ceyhaclis. The next two have the same affinity, but belong more 

 decidedly to the genus Psychotria. 



Psychotria hemicephaelis Wernham, sp. nov. Frutex gla- 

 berrimus, ramulis gracilibus ; foliis crassiuscule coriaceis ellipticis, 

 5-8-5 cm. X l"5-3 cm., utrinque leniter angustatis basi in petiolum 

 brevissimum v. obsoletum, apice acutis, venis secundariis multis 

 approximatis, stipidis ovatis parvis subintegris v. apice breviter 

 bifidis. Floribus glaberrimis in capitulis involucratis post anthesin 

 in umbellis compositis laxescentibus, pedunculo ca. 3 cm. longo, 

 bracteis ellipticis exterioribus ca. 1-8 cm. x 8 mm. interioribus 

 minoribus ; calyce minuto subcarnoso limbo dentato ; corolla 

 gracillima 9 mm. longa, lobis 5 vix 1 mm. longis obtusissimis. 

 Bacca parva ellipsoidea glabrata costata a calyce persistente parum 

 accrescente coronata.

Eelated to P. oblita, next to be described ; readily distinguished 

 by the smaller and more slender corolla, and the more compact 

 head, as w'ell as by the larger and relatively narrower leaves. 



Psychotria oblita Wernham, sp. nov. Glaberrimus, ramulis 

 angulato-compressis ; foliis crassiusculis ellipticis, 4-5-8-5 cm.
