papillose lower surface of the leaves. 
On the other hand, the name applied here to this species may be no definitive. I did not 
see authentic material of Laurus montana, which is an older name than Laurus triplinervis. The 
former species was based on Swartz 15/3 collection, but the specimen(s) could not be found in 
the loans at hand. However, there is a Swartz collection at BM without number and no additional 
information which is annotated as Laurs montana, but clearly belongs to C. triplinerve. If it can 
be proved later that L. montana is conspecific with C. triplinerve, then the name will have to be 
changed to Cinnamomum montanum (Swartz) Berchtold & J. Presl. 
Specimens with appressed hairs on twigs and lower leaf surface, leaves only with primary 
domatia, single inflorescenses, and pubescent tepals outside, match the types of Phoebe 
heterotepala, P. johnstonii, P. mexicana (in part Linden 20), P. pichisensis, and P. poeppigii. 
This morphotype is apparently the most abundant in the area of study. A slight variation to 
inflorescences clustered on short axillary twigs, a condition which is found over all the 
distribution range of the species, fits types of P. mexicana (Linden 20, in part) and P. mexicana 
var. bourgeauviana. Within these two groups there are still two more subgroups recognizable by 
the abundance and length of hairs on the lower leaf surface; one group has leaves conspicuously 
pubescent underneath, and is found here and there from southern Mexico to northern Venezuela, 
the second group, with leaves inconspicuously pubescent underneath is found throughout the 
species range distribution. So far, no name has been created for the pubescent variety. 
Type of Phoebe paraguariensis (partially), and Ocotea flavescens, represent slight 
variations to the big group mentioned above, with hairs spreading to erect on twigs, and 
secondary domatia sometimes present respectively. Most of the flowers in type material of P.
