1. M. myristica, Dun. Anon. p. 80 ; foliis oblongis subcuneatisve vix acuminatis basi 
obtusis, pedunculis in ramulis hornotinis apice bracteatis, sepalis undulatis acumi- 
natis, petalis interioribus late ovatis basi brevissime abrupteque cOntractis margine 
dorsoque pubescentibus vix foveolatis, stigmate subintegro, fructu magno globoso. 
Arbor. Folia 4-5 poll, longa, 1-2 poll, lata, rigidula. Pedunculi in ramulis brevibus 
laterales oppositifolii v. terminales, in speciminibus suppetentibus 2-3-pollicares, sed 
ex Bancroftio interdum longiores. 
According to Welwitsch, Journ. Linn. Soc. iii. 151, the true M. myristica is a native 
of the primaeval forests of the district from the Quizembo river, north of Ambriz, to the 
mouth of the Coanza. I only know it from specimens cultivated in Jamaica under the 
name of Calabash Nutmeg, as figured in the Botanical Magazine, t. 3059. 
2. M. grandiflora, sp. n. ; foliis obovali- v. elliptico-oblongis brevissime acuminatis 
basi obtusis, pedunculis in ramulis hornotinis supra medium bracteatis, sepalis undu- 
latis acuminatis, petalis interioribus late ovato-triangularibus subcordatis, auriculis 
hispidis inflexis intus foveolatis basi brevissime abrupteque contractis, stigmate 
lobulato, fructu magno globoso. — Folia ramulorum fioralium 4-6 poll, longa, \\-2\ 
poll, lata, tenuiora quam in M. myristica ; caulina interdum pedalia, 4-5 poll. lata. 
Inflorescentia M. myristica?, sed pedunculi longiores graciliores, bractea foliacea acu- 
minata longe infra florem sita. Petala exteriora usque ad 4 poll, longa, ut in M. 
myristica undulata et variegata; interiora pollicaria, obtusa, concava, conniventia. 
Eructus usque ad 6 poll, diametro, extus longitudinaliter plus minus conspicue 
striatus, pericarpio crasso lignoso. Semina numerosissima, absque ordine in pulpa 
immersa. 
Aylopia undulata, P. de Beauv. Fl. Ow. et Ben. i. 27, t. 16. excl. fr. 
Ambas Bay, Princes Island and St. Thomas's Island, West Africa (G. Mann). 
Observing a note to Dr. Bancroft's specimens of the M. myristica, that the flowers are 
often very much larger than they are there shown, I had some doubts whether the M. 
grandiflora might not be the same species, as they certainly agree in many points ; but 
the leaves are very much larger, instead of being smaller as one would expect in the wild 
type, the peduncles much longer and more slender ; the bract is always from a half to 
two-thirds way up the peduncle, instead of close under the flower ; the shape of the inner 
petals, as well as can be judged in the dried state, is different, and the stigma is very 
decidedly many-lobed. Whether the two forms may or not be connected by Dr. 
Welwitseh's specimens remains to be seen.
