generally longer than the others and much longer than the fruit. 
In one section the segments of fruiting-calyx shorter or not 
much longer than the fruit. 
The ripe seed generally without albumen. The cotyledons 
thick, fleshy, generally both bifid to their base, that is to the 
point where they are attached to the apex of the hypocotyl 
(radicle) or to the petioles, which in some species are well 
developed in the seed (S. robusta, obtusa). Sometimes (S. bra- 
chyptera) one cotyledon only is bifid, the other being emarginate. 
Two types may be distinguished, which are, however, connected 
by intermediate forms. In the seeds of the first type the lobes 
of the cotyledons are three-sided, prismatic, the two inner faces 
flat, the third outer face rounded, and in that case the hypocotyl 
is imbedded in a groove between the inner edges of the four 
cotyledonary lobes. In the second type one of the cotyledons is 
concave and embraces the other. In this case the hypocotyl 
(radicle) and petioles, if developed in the seed, are imbedded in a 
groove between the two lobes of the outer (radicular) cotyledon. 
In some cases the outer, in others the inner cotyledon is larger. 
The embryo of the first type is found in S. stenoptera, aptera, 
and brachyptera, all of section Brachyptera, in Faguetiana of 
Pinanga, and in leprosula and Curtisit of Mutica. The second 
type is represented by S. robusta and obtusa of Eushorea, by 
Pinanga and macroptera (sect. Pinanga), and by glauca of section 
Mutica. The cells of the cotyledons are mainly filled with starch 
in S. robusta and obtusa of sect. Eushorea, and in S. Curtisit of 
sect. Mutica, with fat-oil in S. stenoptera, aptera, and scaberrima 
of sect. Brachyptera and in S. Pinanya and Gysbertsiana of sect.. 
Pinanga, while S. glauca and leprosula of sect. Mutica and ma- 
macroptera of sect. Pinanga contain both starch and oil. The 
placenta is lignified and to it are attached the membranous 
remains of the dissepiments, and these intrude between the lobes 
of the inner (placentary) cotyledon. 
The base of a leaf-bearing internode has from 3 to 30 resin- 
ducts in the cireumference of the pith. In some species of 
section Anthoshorea these ducts are exceedingly small, not larger 
than the cells of the pith; ordinarily, however, their diameter is 
3 to 5 times that of the ordinary pith-cells. As a rule there are 
3 leaf-traces, two lateral and one apical, each with a resin-duct ; 
the apical trace sometimes with several duets. The two lateral 
traces separate from the central cylinder and enter the bark at
