248 ARRUDA'S BRAZILIAN PLANTS. in Mem. Acad. Scienc. Lisboa, iii. (Mem. dos Correspondentes, p. 34, t. 4 (cochleacarpos) is certainly identical with this. Jackson (who spells it cochliocarpos) refers it to Pithecolohium Auaremotemo Mart. ; but Martins himself when publishing that species (in Flora, XX. Beibl. ii, 115) cited Gomes's plant as a doubtful synonym, and in this he is followed by Bentham (in Fl. Bras. xv. ii. 435). Martins, Allemao, and Bentham all agree in confining **Bar- batimao" to Stryphnodendron Barhatimam Mart.: the Brazilian name for the Pithecolobium is " Auaremo-temo " — a name which Gomes cites from Piso as synonymous with *' Barbatimao," but I think incorrectly. MoRONOBEA ESCULENTA. BacuH. Kostcr, 490. In the Index Kewemis this is identified with M. coccinea Aubl., which *'= [M.] grandiflora, Symphonia globulifera." Martius when estabhshing Platonia (Nov. Gen. & Sp. iii. 169) cited Arruda's plant as identical with his genus, and this determination is borne out by later authors — e.g. Engler in Fl. Bras. xii. i. 467, Peckolt, Hist. PI. Alim. Gozo, iv. 6 (1878), and by Miers and Allemao, who assign the name Bacubi" exclusively to Platonia insignis. Myrtus caryophylata. Crave do Maranham. Koster, 490. No doubt = M. caryophyllata Veil. Fl. Flum. 216, v. t. 70 = iii. P.seiido-caryophyllus Gomes in Mem. Acad. Lisb. iii. (Mem. Corresp. 92) = Eugenia Pseitdo-caryophyllm DC. Prodr. iii. 282. Jackson does not quote Vellozo's name, perhaps thinking it identical with M. caryophyllata L., which, however, is an Old World plant. Myrtus scabra. Mandapuca. Koster, 491. Pleragina* rufa. Oiti Coroia, Pleragina odorata. Oiti da Praia, Pleragina umbrosissima. Oiticica or Catingueira. Koster, 499. Miers identifies P. rufa with Couepia grandiflora Benth., and P. odorata with C, Uiti Benth., citing in each case from his own memoranda the same local name ; and Sir Joseph Hooker (Fl. Bras, xiv. ii. 76, note) gives the same identification, which has been over- looked in the Index Kewensls. P. umbrosissima is not so easy to determine. Arruda's description is as follows : — " The third species (oiticica) is peculiar to the Sertoens, where it grows upon the borders of rivers and rivulets. It rises to the height of 50 or 60 ft. ; its branches are so diffuse, and double so much, that they nearly reach the ground, forming a spacious cope. The fruit is an oblong drupe of two inches or more in length, and of half an inch in thickness ; it always retains its green colour, even when ripe. The kernel is not hard like the kernels of the two pre- • This is one of the few cases in which Mr. Jackson has made a curious slip. In Index Kewensis he has — " Plegerina, Arruda, ex Koster, Trav. Bras. 499 (1816), inc. sed. Pleragina, Steud. Norn. ed. i. 632 (1821)." Plegerina is printed neither by Arruda nor Steudel, and, if ever cited, must be attributed to Jackson in Index Kewensis.
