2. BdchanaNia SKSSiLiFOLiA, Blunie Mus. Bot. Lugd. Bat. 1, 184. A 

 shrub or small tree, the youug branches puberulous and not swollen, ulti- 

 mately glabrous. Leaves thinly coriaceous, oblanceolate, always abruptly 

 acuminate at the apex and much narrowed to the base, either with a short 

 petiole or sessile ; the upper surface glabrous and rather dull, the 

 lower pale-brown when dry aud glabrous except often the sparsely 

 adpressed-pubescent midrib; main nerves 13 to 15 pairs, spreadino*, 

 slightly prominent ou the lower surface ; length 3'5 to 7 in., breadth 

 1*5 to 2*5 in. ; petiole none or from '1 to "6 in. long. Panicles pedunculate, 

 exceeding the leaves, slender ; the branches divaricate, and with the 

 flowers crowded towards their apices, sparsely pubescent. Flowers '15 

 in. in diam., on short pedicels. Sepals 5, sub-rotund, puberulous. Petals 

 5 or 6, much larger than the sepals, oblong, bluut with the apices 

 recurved, glabi^ous. Stamens 8 or 10 : the anthers sagittate, the basal 

 lobes rounded and swollen ; the filaments short, thick, compressed. 

 Pistils several. Drupe sub-cordate, rotund, compi-essed, glabrous, about 

 •35 in. long. Miq. Fl. Ind. Bat., Yol. 1, pt. 2, 637 ; Suppl. 523 ; Englerin

This differs from all the forms of B. florida, Schauer, in having; 

 more acuminate leaves of thinner texture, with the midrib pubescent 

 on the lower surface, and with rather more numerous nerves ; and also 

 in having a pubescent panicle and larger fruit. There is considerable 

 variation as to the petiole. In some specimens there is no petiole at all, 

 and it is to these which Blume gave the name B. sessili/olia. Turc- 

 zaninoff's name B. acuminata, being applicable ta all the forms, is a 

 far more appropriate one ; and Sir Joseph Hooker adopts it although 

 the procedure is, as he admits, "against the laws of priority : " for Turc- 

 zauidoff's species was not published until 1858, whereas Blume dates 

 from 1851. 



3. BucHANANiA FLORIDA, Schauer in Nov. Act. Caes. Leop. Carol. 

 XIX, Suppl. 1, 481. A small glabrous tree, young branches close to 

 the leaves, thick and with many cicatrices. Leaves thinly coriaceous, 

 oblong-lanceolate to obovate-oblong, the apex rounded or obtuse ; nar- 

 rowed from below the middle to the broad channelled somewhat winged 

 petiole ; both surfaces shining, reticulate ; main nerves about 12 pairs, 

 the intermediate veins very distinct ; length 4 to 5*5 in., breadth 1-25 

 to 175 in., petiole '5 to '75 in. Panicles crowded about the ends of the
