woods of Kaluaha, Molokai, with flower buds; no. 7066. Owing to very incom- 

 plete material the writer is unable to enlarjie upon Leveille's description. In the 

 writer 's hand is a co-type of Faurie 's no. 203, but without flower and fruit. The 

 writer is very much inclined to reduce this plant to a variety of /-'. clusiaefolia, 

 as it only differs from that species in the rather small subsessile leaves; but 

 owing to insufficient material for study, it is left at present unmolested. It is a 

 small tree, also shrubby.

A small tree much branched; the young naked leaf -buds hirsute, the branches and 

 inflorescence glabrous; leaves vertieillate, in fours, elongated-oblong or slightly spathulate- 

 oblong, chartaceous, 10 to 22.5 cm long. 5 to 7.S em wide, somewhat attenuated at the 

 base, or sometimes obtuse, on a petiole of 2.5 to 3.5 cm, with a strong, prominent midrib, 

 the very numerous primary veins (30 to 50 pairs) running out nearly transversely towards 

 the margin, where they unite with a distinct intra-marginal vein; the leaves are some- 

 what villous pubescent on the under surface, more especially on the midrib, but quite 

 glabrous above; the texture and especially the venation of the leaves gives them some- 

 what the appearance of the larger forms of {Hapota sandjrioensis) Sidero.ri/lon sandwiccnse; 

 flowers in axillary sessile clusters, the pedicels 4 to 6 mm long; calyx 4-parted, the lobes 

 broadly ovate, imbricated in aestivation, about 2 to 3 mm long; petals 4, ralvate, ovate, 

 a third longer than the sepals, not thickened at the apex, stamens 8, much shorter than the 

 petals — evidently from a fertile flower (Eock), filaments linear-lanceolate, glabrous; 

 anthers deltoid-sagittate, adnate-introrse; hypogynous disk very short; ovary glabrous, 

 depressed, globular, 4-lobed, 4-celled, the 4 carpels somewhat united; style a little longer 

 than the ovary; 4-parted nearly to the base, the divisions clavate, stigmatio at and near 

 the summit; the immature capsule is puberulent and deeply four-grooved. 



The above is the original description of this species by Mann, as found in 

 the Ptoceedings of the Boston Society of Natural History, Vol. 10, page 313. In 

 Hillebrand's description of this species the fact that the immature capsule is 

 deeply 4 grooved is omitted, and the writer thinks it altogether wrong to place 

 this species in the key as having cuboid subentire capsules. 



The writer collected specimens of a Pelea on Mt. Waialeale, the summit of 

 Kauai, overlooking directly Kealia and Ilanalei, on the windward side of Kauai, 

 which he must refer as a variety to Pelea sapotaefolia. In trying to place the 

 plant according to Hillebrand's key to the species, the writer was quite unsuc- 

 cessful, as his key calls for cuboid capsules ; however, in looking up the original 

 description of Mann, which is very complete of this species, he came to the con- 

 clusion that the Waialeale plant is a varietj^ of this species. The capsules are 

 deeply 4-lobed when mature, and evidently likewise in the species found at 

 Kealia, of which no one seems to have collected mature capsules. Owing to a 

 plant collected by Knudsen at Waimea, Kauai, with cuboid capsules, Hillebrand, 

 who seemed not to have collected the species, referred it to the latter, and merely 

 took for granted that P. sapotaefolia had also cuboid fruits. The fact is strength- 

 ened by Heller 's statement, who collected Hillebrand 's variety (S, which says :
