paulo elevatis quam gemmis axillaribus bis terve latioribus. Folia 

 laminis 6.5-8.5 cm. latis 15-18 cm. longis, apice basique acutis, supra 

 glabris, subtus in nervis axillisque nervorum hispidulis ; petiolis 

 2-2.5 cm. longis appresse hispidulis, supra canaliculars. Inflorescentia 

 paucibracteata, ramis 4-5 primariis subumbellatim insertis, perlongis, 

 Horis terminalis rhachin multo superantibus ; ramulis ultimis atris dense 

 glutinoso-puberulis ; bracteis foliaceis lineari-lanceolatis. Calyx cylin- 

 dricus 10-sulcatus minute puberulus 6.5 mm. longus leviter 5-dentatus 

 seu potius 5-apiculatus. Corolla alba 2.5 cm. longa, tubo quam calyce 

 vixlongiore; faucibus 11 mm. longis; segmentis limbi 5 cbtrapezoideis, 

 6 mm. longis, inter sinus 10 mm. latis, sub angulis rotundatis 11mm. 

 latis. Stamina 5 ad loborum baseis vix attingentia, tubo in summo 

 adnata ; filamentis deorsum ligulatis sursum teretibus ; antheris 4 mm. 

 longis. Pistillum 14 mm. longum staminibus multo brevius. — Iguala 

 Canon, State of Guerrero, alt. 760 m., 28 December, 1906, Pringle, no. 

 13,912 (type, in hb. Gray). The Mexican allies of Cordia igualensis 

 are Cordia tinifolia Willd. and Cordia gerascanthoides HBK. From 

 the former it differs in its shorter, less pubescent, shallowly dentate 

 calyx, and from the latter in its relatively short stamens, short broad 

 corolla lobes and shallowly dentate calyx.

 longa. Foliorum laminae circumscriptione fere orbiculares basi obtusae 

 vel rotundatae, apice cuspidato-acuminatae margine leniter revolutae,

 8-10 solito acutioribus altioribusque. Petioli ca. 2 mm. longi. Verticil- 

 lastri 1— 3-flori, axillares, post anthesin foliis aequilongi vel longiores, 

 breviter pedunculati, supremi fere sessiles. Pedicelli 4-5 mm. longi. 

 Floris terminalis bracteolae calycis basin paulo superantes, anguste

 subulatae. Calyx maturus 7 mm. longus prominule nervosus, antice 

 leviter gibbosus, intus a pilorum annulo in faucibus posito obseptus ; 

 labri dentibus setaceis leviter arcuatis quam eis labioli divergentibus

 labro ovato apice leviter-bilobato ; labiolo trilobate, lobis lateralibus
