NEW RUBIACEiE FROM TROPICAL AMERICA. — II. 



By H. F. Wernham, B.Sc. 

 (Continued from Journ. Bot. 1912, p. 244.) 



Pteridocalyx minor, sp. nov. Frutex 3-pedalis, ramulis 

 strigoso-pubescentibus ; foliis elliptico-lanceolatis, utrinque leniter 

 et longiuscule acuminatis apice acuto, utrinque nisi in venis 

 appresse pubescentibus fere glabris, petiolatis, stipulis triangu- 

 laribus acutis integris extus strigilloso-puberulis ; cymis unila- 

 teralibus pubescentibus multifloris, bracteis lanceolatis, floribus 

 secundis ; calycis lobis lineari-lanceolatis nisi uno in laminam 

 saepius elliptico-lanceolatam utrinque acuminatam acutam pro- 

 ducto ; corolla tubo cylindraceo extus sparse praesertim basin 

 versus puberulo, lobis oblongis obtusis glabrescentibus ; capsula 

 anguste oblonga obtusa sparse strigillosa.

The leaves are almost exactly similar to those of P. Appumi, 

 the only other species hitherto described (Wernham in Journ. Bot. 

 xlix. 317), measuring 10-16 cm. x 4-5-5 cm., with petiole about 

 2 cm. long. Stipules 3 mm. long. Peduncle to 3*5 cm. In- 

 florescence about 5 cm. broad. Flowering calyx-lobes 2-3 mm., 

 the foliaceous lobe to 4 mm. x 5 mm. with stalk 3 mm. long. 

 Corolla-tube 16 mm. long, 1 mm. wide, lobes 5-5 mm. x 2 mm. 



The chief distinction from P. Appunii lies in the undivided 

 stipules, the much narrower foliaceous calyx-segments, and the 

 wider corolla-tube. 



My thanks are due to the kindness of Dr. Stapf, Keeper of the 

 Kew Herbarium, in placing this interesting plant at my disposal 

 for examination. 



Tournefortiopsis minor, sp. nov. Frutex sempervirens 

 ramulis praesertim novellis araneoso-lanuginosis ; foliis coriaceis 

 lanceolatis ad 12 cm. x 4 cm. utrinque leniter angustatis obtusis 

 supra glaberrimis nitentibus subtus discoloribus densissime flavo- 

 lanuginosis, petiolo ad 1-5-2 cm., stipidis ovatis acuminatis acutis 

 ad 12 mm. longis membranaceis extus glabris ; floribus dilute 

 rubentibus in cymis unilateralibus dichotomis multifloris axillari- 

 bus secundis ramis ad 3 cm. pedunculo 1-1-3 cm. longis ; calyce 

 breviter et obscuriuscule dentato ; bacca tota vix 4 mm. longa 

 glabra ovoidea nigra, calyce persistente obscuro.

Distinguishable from the Bolivian T. reticulata Rusby, the 

 only other species, by the smaller stipules and berries, and the 

 subentire calyx-limb, which is only just perceptible in the fruit. 



Gonzalea grisea, sp. nov. Frutex ramulis sparsiuscule griseo- 

 strigosis ; foliis ovato-lanceolatis ad ca. 16 cm. x 5-8 cm. longe 

 acuminatis acutissimis basi saepius acutis, petiolo vix 1 cm. attin- 

 gente, utrinque praecipue in venis sparsim asperulo-strigosis, 

 stipulis a basi triangulari parvo in setam ad 8 mm. longam pro-
