248 ARRUDA's BRAZILIAN PLANTS. 



in Mem. Acad. Scienc. Lisboa, iii. (Mem. dos Correspondentes, 

 p. 34, t. 4 icocldeacurpos) is certainly identical with this. Jackson 

 (who spells it cochliocarpos) refers it to Plthecolohhun 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, Allemiio, and Bentham all agree in confining "Bar- 

 batimao" to Stryphnodendron Barbatimarn 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. BacitH. Kostcr, 490. 



In the Index Kewensis this is identified with ilf. coccinea Aubl., 

 which "= [M.] grandiflora, Symphonia globulifera." Martins when 

 estabUshing 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.r/. Engler in Fl. Bras. xii. i. 467, Peckolt, Hist. 

 PI. Alim. Gozo, iv. 6 (1878), and by Miers and AUemao, who 

 assign the name " Bacubi" exclusively to Platonia insignis. 



Myrtus caryophylata. Crave do Maranham. Koster, 490. 



No doubt = il/. cari/ophyllata Veil. Fi. Flum. 216, v. t. 70 = 

 iii. Pseudo-cari/ophyllus Gomes in Mem. Acad. Lisb. iii. (Mem. 

 Corresp. 92) = Eugenia Pseudo-caryophyllus DC. Prodr. iii. 282. 

 Jackson does not quote Vellozo's name, perhaps thinking it 

 identical with M. caryophyUata L., which, however, is an Old 

 World plant. 



Myrtus scabra. Mandapuck. 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 Kewensis. 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 60 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 Keioensis he has — 



"PiiEGERiNA, Arruda, ex Koster, Trav. Bras. 499 (1816), inc. sed. 

 Pleragina, Steud. Nom. ed. i. 632 (1821)." 



Plegerina is printed neither by Arruda nor Steudel, and, if ever cited, must be 

 attributed to Jackson in Index Keivensis.
