chotome corymbosis, ovario glabro.— Habitus et folia L. Thamniee; 

 hsec vero angustiora, parce pellucido-punctata. Corymbi foliis 2-3-plo 

 breviores, 8-20-flori. Flores albi, quam in L. Thamnia vix minores. 

 Sepala vulgo 5, omnia petaloidea. Stylus stamina fere requans, apice 

 obtusus. 

 A small tree with the habit of&Psidium, gathered by Spruce in the gapo 

 on the Solimoes in N. Brazil, in June 1851. 



4?. L. floribunda, R. Spruce, PI. Exs. n. 1580. 



This is probably a variety of the L. corymbulosa, with looser corymbs of 

 smaller greenish flowers and broader leaves ; but the specimens are scarcely 

 sufficient to form a correct judgment. They were from a small tree in the 

 gapd atManaguiri, near the confluence of the Solimoes and the Rio Negro, 

 gathered by Spruce in June 1851. 



** Folia coriacea impunctata. Sepala firmiora. Stamina numerosa. 



5?. L. lucida, Tul. in Ann. Sc. Nat. Par. ser. 3. vii. p. 286. 



Hab. Columbia. 



I have not seen this plant, but from Tulasne's detailed description it 

 would appear to differ from the two following species in the absence of the 

 cupular bracts; and still more so, as indeed from the rest of the genus, in 

 its placentas bearing 2 ovules only, and in its sessile stigma. 



6. L. cupulata, Spruce, PI. Exs. n. 3200. Foliis oblongis ellipticisve 

 coriaceis nitidis, floribus fasciculatis, pedicellis basi bractea cupulata 

 fultis et ea plus duplo longioribus.— Arbor parva (25-pedalis), ramis 

 paucis elongatis. Folia 4-6-pollicaria, breve petiolata. Cupula; sub- 

 sessdes, crassa?, fere 2 lin. longaj. Sepala 4-6, carnea, utrinque 

 tomentella, reflexa, circa 3 lin. longa. Stamina numerosissima, atro- 

 purpurea. Ovarium tomentosum. Ovula in placentis 10-12. Stylus 

 glaber, elongatus, stigmate breviter 3-fido. Fructus ovoideus, erasso- 

 coriaceus, tomentosus, in valvulas 3 dehiscens. Semina non vidi. 



Hab. In woods on the Casiquiare, above the mouth of the river Vasiva, 

 in Venezuela; gathered by Spruce in December 1853. 



7. L. coriacea, R. Spruce, PI. Exs. n. 2730. Foliis oblongis acumi- 

 natis coriaceis nitidis, floribus fasciculatis, pedicellis basi bractea cupu- 

 lata fultis et earn subaequantibus.— Folia quam in L. cupulata vulgo 

 longiora, angustiora. Cupula floridse in axillis arete sessiles, paucae, 

 subglobosa;. Pedicelli brevissimi, tomentosi. Flores carnei, quam in 

 L. cupulata minores ; sepalis proportione latioribus. Fructus junior 

 globosus, dense tomentosus. Cetera fere L. cupulata. 



Hab. A small tree, seldom above 12 feet high, in the woods near Tomo, 

 on the Guainia or Upper Rio Negro, in Venezuela, and near Panure 

 on the Rio Uaupes in N. Brazil * R. Spruce. 



• In some former papers in this Journal, I had, by mistake, mentioned the 

 Kio Uaupes as being in Venezuela instead of N. Brazil.
