MR. JOHN MIERS ON THE GENUS CRESCENTIA. 177 



long, and supported by the solidified disk 8 lines in diameter, upon a peduncle 2 inches 

 long. 



Lamarck, in his 'Illustrations,' tab. 547, to show the structure of Crescentia, made an 

 incorrect copy of Plumier's drawing of this species, omitting the most remarkable feature, 

 the duplicature of the tube of the corolla; and he copied Burmann's (not Plumier's) very 

 incorrect drawing of the fruit and seeds, which belong to some species of Bucrcsceulia. 



13. Crescentia coriacea, nob. : ramulis teretibus, axillis cupuloso-nodosis ; foliis 



elongato-oblongis, imo cuneatis, apice truncato-rotundatis, subito brevissime apicu- 

 latis, subcoriaceis, nervis utrinque 12-14 divaricato-patulis intra marginem arcua- 

 tim nexis, supra subnitidis, rugulosis, nervis immersis, subtus pallidioribus, glaucis, 

 marginibus valde revolutis, costa nervisque prominentibus, petiolo brevissimo, crasso : 

 flore solitario, axillari aut terminali; corolla campanulata, tubo ad basin breviter 

 latiore, sursum gradatim infundibuliformi, fauce ampliata, obliqua, hinc antice 

 inflata et transversim sursum introflexa, limbo 2-labiato, labio superiore multo 

 majore, indiviso, erecto, crispatim undulato, inferiore brevi, vix lobato, reflexo, 

 margine dentatim inciso ; staminibus superioribus exsertis : fructu obovato, sub- 

 conico, apiculo tenui superato, imo disco indurato suffulto, pericarpio sublignoso, 

 tenuissimo, fragili, fusco, intus pulposo, nervis 4 parietalibus in membranam la- 

 minarem adhserentem immersis, pulpa sicca submedullari, seminibus cordiformi- 

 orbicularibus, crassiusculis, majoribus. — In America meridionali et in Antillis : v. s. 

 in Kb. Miis. Brit. Jamaica (B. Browne ?) ; Venezuela, ad Boca del Tigre {Moritz 

 1953) ; in lib. Hook. Jamaica (Dr. Alexander Brior). 



This is a species very different from any of the preceding, in the shape of the leaves, 

 their nervation, the structure of the corolla, and the form of the fruit. The branch is 

 terete, 2-3 lines thick, with axils 1-1J inch apart : the leaves are 6J-9J inches long, 

 2j-3f inches broad, on a thick petiole only 3 lines long. The peduncle is 2 inches 

 long. There is some resemblance in the form of the flower to that of C. cucurbitina, 

 but with this essential difference, that in the latter the upper lip is shortest, while here 

 it is considerably longer, and vice versa in regard to the lower lip. The calyx, like thai 

 in C. cucurbit ma, is 1^—2 inches long ; the tube of the corolla is 2 inches long, the 

 upper lip 1 inch long, the lower incised Up J inch broad ; the transverse duplicature, 3 

 lines below the mouth on the ventral side, gives it a ringent appearance, as in C. obocata. 

 The fruit is 3 h, inches long, 2 inches in diameter, somewhat tapering upwards above the 

 middle ; the pericarp is only one-third the thickness of that in C. cucurbitina, is very 

 brittle, with an external rugose surface, subpolished, dark, and is lined internally with 

 a pale brown, laminated, membranaceous coating, in which the 4 placentary nervures are 

 imbedded. The seeds are large, thick, and quite like those figured by Gaertner ; the 

 pulp which encloses them has a very different texture from that found in the preceding 

 section, being of an almost pithy consistence, which does not grow black, and remains 

 somewhat viscous in drying : the seeds are of a darkish colour, suborbicular, deeply 

 emarginated at top and bottom, somewhat compressed, with a deep groove along each 

 face, in one of which is seen the line of the raphe terminating in the hiluni a little
