MYRTACE^. 
408. Campomanesia glabra, Bcnth. in Hook. Journ. of Bot. vol. ii. p. 319.— ^Alprs. Hop. vol. 
ii. p. ITO.—Myrius chlorocarpa, Bcntli. MS. in Herb. Hook.! — Myrlus? GatUieana, Mart., De 
Cand. Prodr. vol. iii. p. 240. Common all over the Isthmus; Chafes (Fcndlcr, no. 105). 
A shrub op small tree, closely allied to Myrtus amhrosina, Moritz. Leaves varyinj:; in size, and either 
jwjute or long acuminate at the apex. It is apparently T\-idely distributed over the South American conti- 
nent, having been collected in Demerara (Parker) and in Essequibo (Scbomburgli) ; as well as at Par,-! 
(Spruce), Barra (Spruce), and some other not specified place in Brazil (Sullow). 
409. PsiDiUM Guaiava, Raddi, Mem. 1832, p. 2.~P. pyriferum, hum., Do Cand. Prodr. vol. 
iii. p. 233. — P.pomiferum, Linn., De Cand. 1. c. p. 234!— Nomen vcmacul. "Gnayavo." Common 
all over the country, and also cnltivatcd in gardens on account of its edible fruit. 
I confess myself, hke Eaddi, xmable to distinguish P. pyriferum., Linn., from P. pomifcrum, Linn. In 
the former the fruit is stated to be more stretched and nan-owed at the base, in the latter it is more or lew 
globose, but the transition from the one foirm to the other is so clearly observable, if any number of fruits 
are examined, that no importance can possibly be attached to the form; and, as also the form of the leaves, 
the hairy covering of the foliage, and the number and division of the peduncles, the taste of the pulp, are 
subject to great variation, it would probably be wise if Botanists were to follow Eaddi and myself in uniting 
F. pyriferum and pomiferum, adopting either the name which Eaddi lias proposed, P. Guaiava, Raddi, or 
one of those given by Linnjeus to the plant. — In the Isthmus this tree is termed Guayavo, whence the 
English colonial name Guava ; its fruit is eaten either raw or boiled as sweetmeat. 
410. VsiDivM polycarpon, Lamb., De Cand. Prodr. vol. iii. p. 235.— Nomina vernacul. " Guayavo 
de savana" et '' Guayavo peludo." Common in savanas, all over the Isthmus. 
A slu:ub 3-8 feet high, — widely distributed in tropical America (Cuming, no. 1273). 
411. Calyptrantes Schlechtcndaliana, Seem, — Myrcia aromatica, Schlccht., Liunrca, vol. xiii. 
p. 415 ! In dark forests of the Island of Coyba, coast of Veraguas; Island of Taboga (Hinds). 
Schlcchtcndal, not seeing the lateral operculum of the calyx, referred this specie to ITyrda ; fortunately 
he described it so well in other respects, as far as his imperfect materials woidd pernut, that better speci- 
mens at once enabled me to identify and refer the plant to its proper genus. 
412. Eugenia Arayan, Seem. — Myrtvs? Arayan, H.B. K., Nov. Gen. Am. vol. vi. p. 133; 
fruticosaj ramulis liirtellis, foUis ovato-oblongis basi cuneatis apicc acutis rcticulatis glabris nitidis, 
pedunculis axillaribus folio sequantibus apice dichotome cymosis 7-floris ^-el abortu 1- vel 2-flori8, 
floribus in dichotomia sessUibus cseteris pcdicellatis, ealycibus 4-fidis, lobis obtusis. Outskirts of 
woods, Volcano of Chiriqui, Veraguas. 
This species is allied to E. alaternifolia, Benth., and IE. pycnantlia, Benth. It was found by Jameson 
on the Andes of Ecuador, where it had previously been collected by Humboldt and Bonpland, and is called 
Arayan. 
413. Eugenia Guayaquilensis, De Cand. Prodr. vol. iii. p. 275. Island of Coyba, coast of 
Veraguas. 
414. Eugenia scrkiflora, Benth. in Bot. Sulph. p. 98. — TVlprs. Rep. vol. v, p. 753. Common 
all over the country.
