producta, marginibus inferne subulato-dilatatis, Semen quasi tripterum. 
16. P. (Piptilema) cordata, Gray, l.c.; glabra; stipulis ovatis? caducis; foliis oblongo- seu 
lanceolato-ovatis promisse acuminatis basi cordatis longe petiolatis; capitulo arcte sessili co-floro 
bracteis squamaceis obovato-rotundis circiter 6 caducis involucrato; calycis limbo brevi truncato ;

17. P. (Piptilema) Pickeringii, Gray, |.c.; glabra; stipulis caducis; foliis oblongo-lanceo- 
latis seu obovato-oblongis promisse acuminatis basi angustata subacutis obtusisve; capitulo arcte 
sessili oo-floro bracteis squamaceis caducis inyolucrato; calycis limbo brevissimo. truncato; corolla 
tubulosa 4-6-mera; fructibus obovatis obtusis basi 4-angulatis, pyrenis dorso et inferne marginibus 
eristatis— Port Kinnaird, Ovalau (Seemann! n. 251). 
18. P. (Piptilema) tetragona, (sp. nov.) Scem.; glabra; foliis lanceolatis longe acuminatis in 
petiolum attenuatis, venis primariis 12-18-jugis; stipulis caducis; floribus terminalibus capitatis 
paucifloris; drupis oyatis tetragonis seminibus dorso acute carinatis.—Ovalau (Seemann! n. 252). 
Allied to P. Pickeringii. Leaves, including petiole, 5-6 inches long, about 1 inch broad. Flowers 
unknown. Seeds at the back acutely carinate, and thus making the fruit 4-cornered. 
19. P. (Piptilema) bullata, (sp. nov.) Seem.; erecta; ramulis petiolis bracteisque rufo-hir- 
sutis; foliis ovali-lanceolatis acuminatis, basi acutis, bullatis, supra glabris, subtus ad costas venisque 
rufo-hirsutis; capitulo terminali primum bracteis squamaceis involucrato ; cat. ignot.—Korovono, 
Vanua Levu (Seemann! n. 248). 
A shrub, 4 feet high, of which only a couple of specimens were found, both having an undeveloped 
flowerliead, enclosed in two large bracts, as is the case in A. Gray’s section Piptilema, But the flowers are 
too young to admit of a closer examination. The plant is easily recognized by its very bullate leaves, and 
will doubtless again be met with. 
90. P. (Piptilema) platycocca, Gray, |.c.; glaberrima; stipulis caducis; foliis oblongis 
utringue acutis; pedunculis terminalibus demum lateralibus petiolam advequantibus glomerulos 1-3 
paucifloros bracteis caducis primum involucratos gerentibus; fructibus ovato-tetraquetris, pyrenis 
dorso et marginibus prasertim inferne acute cristatis—Viti Levu (Seemann! n- 249). 
There are besides several other Vitian specimens in the Kew and British Museum Herbaria, such as 
my n. 250, in fruit, from Namosi, Viti Leyu (probably a near ally of, or identieal with P. casudarwn, 
A. Gray), and my n, 241, as also some seapes collected im A dmiral Denham’s expedition, which had better 
be left undeseribed until more materials have come to hand.
