368 REPORT ON THE PLANTS 
intus excavata, concavitate intus superne costa prominente divisa. 
Stamina ad tertiam partem petali attingentia, latiora quam longa, 
connectivo antherarum a filamento lato crassiusculo haud distincto. 
Stylus petalis brevior. Fructus non visus. 
There are two Humiriacee, the Umir? (Humirium Jloribundum, Mart.) 
mentioned in our first report, and again found abundantly in the neigh- 
bourhood of Santarem, and the Saccoglottis Amazonica, Mart., a much 
. more local species, although frequent on the margin of forests about 
Santarem. It there forms a spreading tree of about thirty feet, with 
the young leaves of a deep red. Its fruit is called Uarua by the 
Brazilians, and said to be very good eating. 
Among Meliaceæ, the common Azedarach was found, to all appearance 
wild, as a tall shrub or low tree, in the vicinity of Santarem : a Guarea 
from the vicinity of Obidos may possibly be the same as the one pre- 
viously gathered near Parà, both forming lofty trees; the specimens 
were very few, and could only be supplied to the first two or three sets. 
The following new Trichilie are more generally distributed. 
1. Trichilia excelsa; foliis amplis, foliolis 5—7 alternis oppositisque 
ad venas petiolis ramulisque pubescentibus, paniculis brevibus, flori- 
bus vulgo tetrameris, filamentis ultra medium connatis apice biden- 
tatis dentibus antheram glabram superantibus, ovulis collateralibus. 
— Arbor excelsa, ramulis teretibus pube molli haud densa. Petioli 
communes 4-8 poll. longi.  Foliola 3 ultima ad apicem petioli digi- 
tata, 5-6-pollicaria, ezetera minora, opposita v. alterna, omnia ex 
ovata v. oblonga forma in obovatam transeuntia, apice rotundata 
cum acumine brevi et obtuso, margine sspe undulata v. leviter si- 
nuata, basi plus minus angustata et petiolulo brevi fulta, membra- 
nacea, penninervia et reticulato-venosa, supra glabra nisi ad venas 
parce puberula et demum lucidula, subtus tactu mollia, ad costas 
. venasque puberula, pallide virentia. Panicule vix pollicares, a basi 
. ramosissime. Pedicelli ultimi $ lin. longi.  Calyces late et obtuse 
4-lobi, + lin. longi. Petala 2 lin. longa, alba, extus adpresse pube- 
Yula. Stamina undique glabra. Filamenta complanata, glabra, 
paulo ultra medium monadelpha, tubo basi disco carnosulo adnato. 
— Anthere ovate. Ovarium hirsutum, triloculare. Ovula in loculis 
gemina, minutissima, collateralia, medio lateraliter affixa. Stylus 
brevissimus, glaber.—Ovarium in omnibus quos examinavi flores 
 semiabortivum videtur et planta verisimiliter polygamo-subdioica.— 
. From the virgin forests near Santarem.
