1. M. MYRisTiCA, Dun. Anon. p. 80 ; foliis oblongis subcuneatisve vix acuminatis basi 



obtusis, pedunculis in ramulis hornotinis apice bracteatis, sepalis undulatis acumi-

 dorsoque pubescentibus vix foveolatis, stigmate subintegro, fructu magno globoso. — 

 Arbor. Folia 4-5 poll, longa, 1-2 poU. lata, rigidula. Pedunculi in ramulis brevibus

 ex Bancroftio interdum longiores. 



According to Welwitsch, Journ. Linn. Soc. iii. 151, the true 31. 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 Nixtmeg, as figured in the Botanical Magazine, t. 3059. 



2. M. GBANDiFLOKA, 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 floralium 4-6 poll, longa, 1^-2-1^ 

 poll, lata, tenuiora quam in M. mi/ristica ; caulina interdum pedalia, 4-5 poll. lata. 

 Inflorescentia M. myristicce, sed pedunculi longiores graciHores, bractea foliacea acu- 

 minata longe infra florem sita. Petala exteriora usque ad 4 poll, longa, ut in M. 

 myristica undulata et variegata; interiora poUicaria, obtusa, concava, conniventia. 

 Fructus usque ad 6 poll, diametro, extus longitudinaliter plus minus conspicue 

 striatus, joericarpio crasso lignoso. Semina numerosissima, absque ordine in pulpa 

 immersa.

Observing a note to Dr. Bancroft's specimens of the 3£. myristica, that the flowers are 

 often very much larger than they are there shown, I had some doubts whether the M. 

 graiidijlora 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. 

 Welwitsch' s specimens remains to be seen.
