interzonary band is 4 lines high ; the upper zone is 2 in. in diam., has a sharp lip turn- 

 ing outwards ; the operculum, a trifle wider, is 2 J in. in diam., and 3 lines high. Martius, 

 as well as Burchell, collected the fruits lying on the ground, hut did not find the seeds. 



7. Allantoma scutellata, nob. : planta ignota : racemis fructiferis axillaribus, longi- 



usculis, angulatis; rachi crebre nodosa, multiflora; floribus sessilibus: pyxidio 

 obconice cylindrico, ochraceo-brunneo, valde opaco, imo sensim obtuso, paullo sul) 

 apicem zona calycari subacute lineari prominula cincto; vitta interzonali acclive 

 convexa, diametri 7tam partem alta; zona superiore circulari, calycari angustiore; 



+ 



operculo tenuiuscule scutelliformi, depressissime pulvinato, vertice conoavo, medio 

 brevitcr umbonato; columella ei infra adnata, fere ad basin descendente, solide 

 crassa, faucem implente, subtus 4-angulata, 4-sulcata, angulis ad parietem agglu- 

 tinatis et hoc modo loculos 4 efficientibus ; angulis demum solutis hsec cum semi- 

 nibus dccidit ; pericarpio subtenuiter coriaceo ; seminibus paucis, lineari-oblongis, 

 compressis, imo 2-auriculatis, undique grossule rugosis, fuscis, erectis, cum hilo 

 subYcntrali ct basalari. In Brasilia: v. 8. fruct. in Mus. Soc. Linn, (sine loco), 

 Capt. Sir E. Homo; in collect. Mus. Brit, (sine indicat.). 



There can be no doubt that this fruit belongs to Allantoma. The rachis of its many- 



g raceme is about 6 in. long, with alternate prominent cicatrices 1-2 lines apart 



the pyxidium (Plate LXV. fig. 1) is ^-^ in., long, 11-2 in. in diam. below the 



talycary zone, and tapering downwards ; the calycary zone, 3 in. above the base, is If 

 in. in diam. ; the interzonal band is 3-4 lines high, very convex, narrowing above ; the 

 upper zone is 1 J-lf in. in diam. ; the operculum is orbicular, of the same diameter, is 

 H lino high, with a rounded edge, umbonate in its concave vertex, is attached to a 

 central columella 2 in. long, filling the mouth of the pericarp, descending to the base, 

 sharply 4-ajigled, with 4 broad hoUowish intervals, which form the ceUs ; pericarp li 

 line thick, cylindrical within ; seeds, by abortion, only 4 in the specimen examined, 19 

 hues long, 4 lines broad, 1 Hne thick, fuscous, attached to the base of the columella at 

 tlic inner face, by a small hilum upon one of its basal auricles. There is a Httle differ- 

 ence iu the somewhat broader shape and narrower interzonal band in the British- 

 Museum specimen, which wants the operculum and seeds.

This fruit (Plate LXV. fig. 9) differs from that of A. macrocarpa in its erect inter 

 nal baud, turned inwards at the summit (not outwardly), and in its thicker bark; it «
