HENRIQUEZIA OF SPRUCE. — | Eo 297 
Å single specimen was gathered by Mr. Spruce, in June 1854, in woods along the 
Guiainia, or Upper Rio Negro, above the confluence of the Casiquiare. 
3. HENRIQUEZIA NITIDA, Spruce, M$.; foliis longe oblongis obtusis crasso-coriaceis 
nitidis, venis vix prominulis, calycis 4-partiti laciniis subovatis acutis imbricantibus, 
corolla extus sericeo-villosa. i 
Arbor 30-pedalis, ramosissima. Folia (an constanter ?) ternatim verticillata, 8-10 poll. longa, 2-3 poll. 
lata, basi angustata, utrinque viridia et nitida, costa utrinque prominula ; venæ tamen primariae parum 
conspicuæ et non prominentes.  Sfipulæ lineari-lanceolatæ, pollicares, rigidæ, persistentes. Paniculæ 
rami ternatim. verticillati, dichotome cymosi, cano-tomentosi. Calycis limbus usque ad ovarium 
divisus; lacinie 5 lin. longæ, tomentosæ, multo latiores quam in H. verticillata, marginibus imbri- 
cantibus. Corolla sesquipollicaris, rosea maculis nonnullis cinnabarinis notata, intus prater lineam _ 
pilorum flavicantium glabra, extus mollissime sericeo-villosa, fauce latiore quam in H. verticillata. 
Fructus ignotus. ` ; 
Collected by Mr. Spruce in October 1854, on the banks of the Casiquiare, and distri: 
buted under the number 3690. | | 
4. HENRIQUEZIA OBLONGA, Spruce, MS.; foliis anguste oblongis obtusis subcoriaceis 
opacis subtus pallidis, venis vix prominulis, capsula suborbiculari. 
Possibly a variety of the H. nitida; but the specimens of the one being in flower only, 
of the other only in fruit, I do not think it safe to unite them, as the leaves do not quite 
agree. In the H. oblonga they are scarcely 6 inches long, although with longer petioles 
than in H. nitida, not so thick, and not nearly so shining, and much paler underneath. 
The stipules are nearly the same. The capsule is of the same woody consistence as in 
H. obovata, but not broader than long, being about 3 inches each way; it is marked with 
a similar slightly-arched transverse line, being the scar left by the limb of the calyx. 
. À small tree of about 18 feet in height, with few spreading branches; frequent on the 
-Rio Atabapo, an affluent òf the Orenoco near the mouth of the Casiquiare. There were 
only two or three specimens gathered by Mr. Spruce in June 1854, and numbered 3702.
