425-434). 



The Polypetalae were worked out by tlie collector, but only 

 diagnoses of tlie new species were published, as it was intended 

 tbat the list of plants collected should appear as a whole. It has 

 now been decided to publish the enumeration in parts, and the 

 present instalment, comprising the Rubiaceae, will be followed 

 by others, including the Polypetalae and the remainder of the 

 Gamopetalae.

Manettia coccocypseloides, Wernham; affinis M. racemosae, 



Ruiz et Pay., a qua floribus paucioribus minoribus, forma calycis 

 corollaeque distinguitur. 



Herba debilis scandens, caule sparse et obscure puberulo sub- 

 nitente; foliis lanceolatis vel ovato-lanceolatis, circiter 4'5 cm. 

 X 1'7 cm., acuminatis acutissimis, utrinque sparsiuscule griseo- 

 puberulis, petiolo bievi ad 8 mm. longo ; stipulis parvis late ovatis ; 

 floribus albis circiter 1 cm. longis in cymis corymbosis paucifloris, 

 pedunculo vix 1'5 cm. longo qua ramuli et pedicelli graciles ad 

 5 mm, sparsiuscule puberulo; bracteis ovalibus mucronatis ad 

 circiter 5 mm. x 2"5 mm. ut folia indutis; calycis lobis 4 lineari- 

 cblongis, 3-4 mm. longis; corolla extra puberula inter minimas 

 tubo giacili insuper leniter nee multo ampliato demum glabres- 

 cente; capsnla subglobosa sparse puberula tardius glabrescente, 



Colombia. Tolima: Pitalito, fl. and fr. March, Sprague 244. 



A delicate little herb, allied to the Venezuelan M. racemosay 

 but readily distinguished by the much smaller flowers fewer 

 together, and the differently shaped calyx and corolla.

 Moriche palms, fl. Not. Sprague 7.

^known specimen was collected at Santarem by Spruce. Sprague's 



specimen seems to have abnormally large flowers, and may possibly 

 be a variety.
