Genus ob flores adhuc ignotos recognoscendum: structura fructus et se- 
minis cum Myrto convenit, inflorescentia anomala foliisque serratis in fa- 
milia singularis: receptacula olei aetherei in foliis investigatione anato- 
mica apparebant. Arbuscula v. frutex ultra 6pedalis, valde ramosus, ha- 
bitu Myrtaceo; folia opposita, 10—16'/^ longa, 5—8% lata; petioli 2, 
pedicelli 1‘, racemi 1—1!/5" longi, hi simplices, nunc tripartiti; bacca 
resinoso-aromatica, 4 diam., limbo calycino parvo demum evanido coro- 
nata; seminum testa exterior dure lignosa, intra arcum embryonis elon- 
gati in septum spurium crassiusculum protrusa, interior libera, membra- 
nacea. — Nom. vernac. Pala blanca, Tucuman, infrequens in sylvis mon-

marginali e basi nervorum lateralium oriundo , pedunculis terminalibus 
et axillaribus trifloris, his folium subaequantibus: floribus breviter pedi- 
cellatis, calycis tubo ovato glanduloso-piloso lobis oblongo-linearibus se- 
tosis demum longiori, petalis (siccis roseis) fimbriato-ciliatis calycis tubo 
plus duplo longioribus obovato-subrotundis, antheris 10 subaequalibus : 
connectivo infra loculos filiformi basi bitesticulato, stylo exserto curvo. — 
Affine videtur P. laxo DC., sed setae foliorum in utraque pagina confor- 
mes substrigoso-patulae. Rami superne compressi, internodiis folia subae- 
quantibus, pilis patentissimis sparsis minuta glandula terminatis setisque 
eglandulosis foliorum 1‘ fere longis; folia membranacea, paullo bullata,
