8 AMERICAN SPECIES OF MYRISTICA. 
I take this opportunity of adding the characters of some new dzo- 
nace from Mr. Spruce's last collections. 
1. Anaxagorea brevipes ; foliis oblongis cuspidatis coriaceis, pedunculis 
solitariis (bifloris) fructiferis petiolum brevissimum excedentibus, fol- 
liculis tenuiter lepidotis.—.47óor parva (20-pedalis). Folia 6-8 
poll. longa, circa 2 poll. lata, petiolo vix 2-lineari, longiuscule cus- 
pidata, basi rotundata, consistentia quam in ceteris speciebus multo 
firmiora, venis minime pellucidis. Flores haud vidi. Pedunculi 
fructiferi circa 3 lin. longi. Calyx parvus, infra fructus patens. 
Receptaculum et folliculi iis 4. pheocarpi a Martio depictis similia. 
Ovaria ultra 12, follieuli tamen abortu szepius pauciores, cum stipite 
pollieares v. paulo longiores, in vivo (teste Spruceo) lutei stipite 
coccineo, in sieco castanei. 
From the forest about Barra do Rio Negro. 
2. Guatteria pteropus; glabrescens, foliis elliptico-oblongis cuspidatis 
 eostatis basi abrupte contractis et secus petiolum decurrentibus, pe- 
dunculis 1-3-nis glabriusculis infra medium articulatis, sepalis ovatis, 
petalis obovato-oblongis ferrugineo-tomentellis.— 475or gracilis, 20- 
pedalis. — Ramuli fusci, novelli tenuissime ferrugineo-tomentelli. 
Folia semipedalia, circa 3 poll. lata, cuspide acutiusculo, versus basin 
angustata v. rotundata, ima basi cuneata et secus petiolum semi- 
‘pollicarem usque ad basin decurrentia; novella minute puberula, 
adulta supra glabrescentia haud nitida, subtus minutissime ferru- 
gineo-tomentella, consistentia rigide membranacea, costa media sub- 
tus valde prominente, venis primariis etiam prominulis parallelis an- 
gulo fere recto a costa divergentibus et intra marginem tenuiter ar- 
. euato-confluentibus. Pedunculi 8-9 lin. longi. Bractee minute, 
. squameeformes. Sepala 2 lin. longa, obtusiuscula. Petala (an per- 
fecte evoluta ?) 5 lin. longa, undulata, primum ferruginea, dein ca- 
nescenti-tomentella, in vivo roseo-virescentia. Bacce haud vise. 
. From the forest on the north shore of the Amazon River at the mouth 
ofthe Rio Negro. Easily recognized by the winged petiole. 
. 8. Anona (Guanabani) sessiliflora ; arborea, remis glabris v. strigillosis, 
foliis (subpedalibus) oblongis v. obovali-oblongis cuspidatis basi in 
petiolum brevem angustatis rigide membranaceis supra glabris sub- 
tus strigillosis, floribus 1-3-nis subsessilibus, sepalis ovatis acutius- 
.. culis, petalis rotundatis crassis acutiusculis dense sericeis, interiori-
