MR. J. MIERS ON THE LECYTHIDACE^. 195 



covered inside all over, somewhat laxly, with longish adpressed starainiferous append- 

 ages, the outer row fimbriating the margin : it is altogether, including the basal ring, 

 18 lines long, 6 lines broad, the hood being 7 lines long and broad; nearly the entire 

 surface of the basal ring is crowded with short staminiferous appendages in many series. 

 This structure is in confirmation of Moricand's determination that it is a species of 

 Couroupita. 



9. Couroupita ceenulata, nob. : ramulis rufo- vel cinereo-brunneis, opacis, rugulosis, 



obsolete striatis ; foliis ovalibus, aut late ovatis, imo rotundatis, subito brevissime 

 acutatis, et in petiolo decurrentibus, apice rotundatis, et in acumen recurvatum 

 brevissimum canaliculatis, in marginibus cartilagineis vix revolutis irregulariter 

 crenatis, chartaceis, supra pallide viridibus, nervis tenuissimis subpatentibus vix 

 prominulis, valde reticulatis, costa tenui, circa basin dilatata et plana, subtus fere 

 concoloribus aut brunnescenti-viridibus, opacis, costa nervis venisque prominulis; 

 petiolo supra piano, late marginato, margine involuto, limbo 8plo breviore : racemo 

 terminali, folio longiore ; rachi flexuosa, subcompressa, striolata ; pediccllis paten- 

 tibus, calyce brevioribus, fuscis, rugulosis ; sepalis subrotundatis, rotatis, fuscis, 

 granoso-rugosis ; petalis suborbicularibus, inaequalibus, concavis, margine ciliatis; 

 ovario infero, turbinato, subangulato, granoso, 4-loculari, ovulis in quoque loculo 

 plurimis, e placenta axillari prominente, funiculis centrifuge radiantibus, vcrtice 

 intra discum latiusculum pauUo prominente, subconcavo, nitido, radiatim striate, 

 margine crenato; stylo centrali, brevi, depresse globose, 4-sulcato; stiginate sessili, 

 hoc minore, depresse globose, obsolete 4-lobo, lobis styli sulcis oppositis. In Brasilia :

The sample of wood sent by Blanchet is about 3 inches in diameter ; it may be part of 

 the main stem, but more probably of one of its branches : the leaves are 3-4J in. long, 

 2-2J in. broad, on a petiole 3-4 lines long, with about 18 pairs of nerves arcuatcly con- 

 joined far within the margin ; the rachis is 5-6 in. long, bearing about 15 flowers, -J-} in. 

 apart. 



3. Bertholletia. (Plate XXXIII. c.) 



The general features of this genus having been so amply demonstrated in the prcli- 

 mmary remarks {mite, p. 161 et seq.), no further observations are here necessary. Only 

 a single species has been hitherto recorded ; but I think two or more may easily be recog- 

 nized in our herbaria.
