There is also in the Kew Herbarium a small flowerless branch 
collected in Uruguay by John Tweedie, of what is apparently the 
same species. Tweedie sailed up the river Uruguay about the year 
1833, and probably botanised in the islands. The following note 
accompanies the specimen : — " This is called among the natives of 
the Uruguay aguya. It is one of the most splendid evergreen 
trees I have met with, and the fruit, resembling a golden knob 
pear, has a finer scent than the pine-apple. The two fruits sent 
are bad specimens." These fruits have disappeared, but those 
sent by the Editor of ' II Giardinaggio ' are pear-shaped. 
Pouteria suavis, Hemsl. [Sapotaceae] ; species nova ex affinitate 
P. (j'irchierianae, a qua foliis angustioribus lanceolatis, fioribus 
dimidio minoribus et sepalis subaequalibus interioribus haud 
truncatis emarginatis differt. 
Arbor ramis floriferis rectis graciliusculis appresse-sericeis. 
Folia glabra, in ramoram apicibus conferta, demum coriacea, 
breviter petiolata, anguste oblonga, oblanceolata vel lanceolata, 
4-15 cm. longa, saepius circiter 10 cm. longa, l-2\5 cm. lata, apice 
obtusa vel rotund ata, basin versus attenuata, supra nitida con- 
spicue venosa. Flares circiter 3-4 mm. diametro, infra folia ad 
foliorum delapsorum axillas fasciculati, numerosi, pedicellis 
s,ri(vis ? t -l mm. Longis. Sepala 4, biseriata, 2 omnino interiora, 
similia, ovata, concava, extus sericea, ciliolata. Corolla fere ad 
medium 4-lobata, lobis rotundatis erectis ciliolatis. 
oblonga, ciliolata, corollae lobis alterna iisque dimidio breviora. 
Stamina corollae lobis isomera et lis opposita, inclusa. Ovarium 
villosum, 2-loculare (an semper ?) stylo glabro brevissime exserto. 
Fructus pyriformis, 4-5 cm. longus, medio 2-5-2-75 cm. diametro, 
glaber, pencarpio carnoso tenui. Semina saepius 2, semiovoidea, 
vel J , ovoideum, testa crassa, ossea. 
Steps have been taken to establish this tree at Eordighera, 
where seeds have been sown in Mr. Garnier's garden. Under 
cultivation the fleshy part of the fruit may possibly be so 
increased as to render it acceptable to a circle outside the 
aborigines of Uruguay.
