NEW RUBIACE^} FROM TROPICAL AMERICA 323 



Trinidad (?) : Anderson 308. 



According to the label, " This beautifull shrub grows on the 

 summits of the highest mountains — is scarce." 



This species is readily distinguishable from the others of the 

 genus by the long narrow leaves, acuminate at both ends, and the 

 lax inflorescences of a few (5-6) flowers with long stalks. 



Leaves 7-1T5 cm. x 1*5— 3*3 cm., petiole 1-2-2 cm., secondary 

 nerves to 9-10 pairs; stipules 3-4 mm. or longer, the apiculus 

 sometimes as much as 3 mm. Flowering racemes 4-5 cm. long, 

 increasing to 10 cm. or more in fruit. Pedicels 1-5 cm. in 

 flowering stage, rapidly increasing to 2*5 cm. or more as the fruit 

 matures. Calyx 2-2 mm. Corolla-tube 2-5 mm., lobes 3 mm. 



Chiocoeca capitata, sp. nov. Verisimiliter frutex erectus 

 ramosus, lignosus, glaberrimus, ramulis striatis, mox cortice pallido 

 cinereo indutis nodosis ; foliis valide chartaceis, ellipticis utrinque 

 angustatis acutis, venis secundariis paucis occlusis ; floribus parvis 

 breviter pedicellatis, in cymis subcapitatis parvis multifloris sessili- 

 bus congestis ; calycis lobis anguste lanceolatis acutis ; corolla 

 anguste infundibulari-tubulosa, lobis latis minusculis reflexis ; 

 antherarum apicibus exsertis ; ovario angusto calycem subaequante 

 v. paullo superante, basi attenuato. . 



Jamaica : Wright. 



Very distinct in the sessile heads of small subtubular flowers. 

 The progressive abbreviation of the inflorescence seems to have 

 been one of the chief evolutionary tendencies within the genus 

 Chiocoeca ; this is illustrated in the following series : C. brachiata, 

 with elongated inflorescence much exceeding the leaves ; G. parvi- 

 folia, with inflorescence barely half as long as the leaves ; and 

 C. capitata, the present species, in which the maximum of abbre- 

 viation has been attained by the close aggregation of the flowers 

 into a head. This congestion is doubtless correlated with the 

 narrow, subtubular form of the corolla. 



Leaves 3-4-7 cm. x 1*5-2 cm., with petiole rarely so much as 

 6 mm. Heads barely 1 cm. in diameter, even including the 

 corollas. Pedicels to 1*5 mm. Calyx-lohes less than 1 mm. Corolla 

 5-6 mm. long, 1*5 mm. wide at the mouth, lobes barely half a 

 millimetre. 



Chiocoeca pachyphylla, sp. nov. Arbor nisi inflorescentia 

 glabra, ramulis rugosulis, lignosis ; foliis crasse coriaceis, ellip- 

 ticis breviter acuminatis obtusis basi acutis petiolatis, supra 

 nitentibus subtus discoloribus, venis centrali supra impressa sub- 

 tus prominente secundariis utrinque 7-8 manifestis nee tamen 

 conspicuis, stipulis latissimis brevibus vaginantibus apiculatis 

 persistentibus ; inflorescentiis laxiuscule paniculatis minute 

 pubescentibus demum glabrescentibus, folia subsequantibus 

 vel superantibus, bracteis minimis ; calycis lobis ovato-oblongis 

 obtusissimis brevibus ; ovario breviter tubuloso mox subgloboso, 

 in bacca globosa glabra breviter pedicellata, a calycis limbo erecto 

 persistente coronata maturante.
