2 lines within tlie mouth ; the pericarp and operculum are about 1^ line thick, botli 

 marked by the traces of the dissepiment ; it contains about 16 seeds, with a coriaceous 

 testa, about U in. long, |-1 in. broad, and J of that thickness ; the embryo presents the 



gular structure of the g

vissimc et acute turbinato, pauUulo supra basin zona calycari e sepalis 6 acutis sub- 

 crectis linea nexis cincto ; vitta interzonali fere erecta, diametri ^—g partem alta ; zona 

 superiore circulari, integra, sequilata ; operculo vitta 3-4plo altiore, convexo, obtuse 



umbonato, intus concavo, septi vestigio signata, cum velario intra fauceni de

 maculato, obsolete 2-loculari ; seminibus plurimis, late oblongis, acute angulatis, apice 

 truncatis, imo gradatim angustioribus et hilo basali biseriatim affixis. In Amazonas : 

 v.fr. s. in Mm, Kew., Uio Negro {Spruce). 



Tlie specimen of the frjait of this species in the Kew Museum differs from that of the 



preceding species in the nearly basal calycary zone. The pyxidium (Plate LXI. fig. 4) 



is IJ in. high, 2-2 J in. broad at the calycary zone, which is 2-3 lines above the base; 



the interzonal band is 3-4 lines high ; the upper zone and operculum are 2-2J in. in 



diam. ; the latter 11-12 lines high, with a velarium descending 2 lines within the 



mouth ; the pericarp and operculum are 2 lines thick ; the seeds much resemble those of 

 J. ohtectum.

UGASTRUM DEPRESSUjr, nob. : planta ignota : pyxidio valde depresso, imo breviter 



late turbinato, sub medium zona calycari imo circulari e sepalis 6 obtusis vel acutis 



linca nexis cincto ; vitta interzonali angusta, suberecta, diametri 8-lOmam partem 



alta ; zona superiore orbiculari, calcycarem subaequante ; operculo pariter sequali, 



depresse pulvinato, superne fere planato aut subconcavo, centro breviter et obtuse 



umbonato, vittaj fere altitudine, intus plane concavo, cum velario subbrevi intra 



faucem descendente, obsolete 2-loculari, intus imo cicatricibus seminum 10 biseriatis 



notato; pericarpio subtenuiter coriaceo; seminibus angulatis, erectis, structura 



generis. In Amazonas : v. s.fr. in Mas. Brit., Uio Negro ( Wallace) ; in Mns. Kew. 

 {Spruce). 



These fruits probably belong to one of tlie many species of Macacarecuya which 

 Dr. Spruce saw near the banks of the Rio Negro, far too high to obtain specimens, 

 the fruits being found on the ground beneath them. The pyxidium (Plate LXI. fig- 13) 

 is l-i; in. higli, 2-2J in. in diam. at the calycary zone, which is \ in. above the gradually 

 contracted base ; the interzonary band is 2-3 lines high ; the upper zone and operculum 

 arc 2 iu, in diam,, the latter 3 lines high, very flattened above, and shortly umbonated 

 in the middle, very concave within, where it is marked by the evanescent dissepiment, 

 its velarium descending 3 lines within the mouth ; the pericarp is rather thin and 

 coriaceous, marked within along the sides with the trace of the dissepiment, and in the 

 bottom by 10 cicatrices in 2 rows, where the seeds were attached ; the seeds are Hke 

 those of J. ohtectum.
