Aegialitis] LXVI. PLUMBAGIXACE.E 413 



Order LXVI. PLUMBAGINACE^l. Gen. PI. ii. (323 



(Plumbaginece). 



Mostly herbs, a few shrubs, fl. regular bisexual, bracts usually scarious on 

 the edge, sheathing the fl. Calyx tubular, 5-ribbed, mouth frequently scarious. 

 Petals 5, free or connate at base, stamens 5, epipetalous. Ovary 1-celled, 

 ovule 1, pendulous from a basal funicle. 



The stems of the two genera here described have an entirely anomalous structure. 

 Voyelia on a transverse section shows concentric- Viands of hast (phloem), alternating 

 with broader strata of wood, similar to Dalbergia paniculata, Cocculus laurifolius and 

 to many climbing shrubs. A transverse section of Jri/inlilis shows numerous distinct 

 vascular bundles consisting of thick-walled wood fibres and a radial line of vessels 

 (Gamble, Indian Timbers, ed. ii. 436). 



1. Aegialitis rotundifolia, Roxb. (.4. annulata, Kurz F. Fl. ii. 96), Mangrove swamps and 

 tidal forests of Bengal and Burma. Andamaus. Malay Peninsula. A simple stemmed, 

 glabrous evergreen shrub, with a thick conical trunk, branch-lets marked by the scars 

 of the amplexicaul petiole. L. alternate, thickly coriaceous, nearly orbicular, blade 

 •2-:-i in. long, petiole sheathing, longer than blade. Fl. in panicled racemes. Calyx 

 tubular 5-ribbed, the ribs ending in short teeth, petals white, linear, the upper 

 portion deciduous, the lower united with the filaments into a persistent tube. Capsule 

 linear, 3 in. long, pentagonal, dehiscing finally along the angles. .1. annulata, E. Br., 

 is a widely spread littoral species of tropical Asia and Australia. 



2. Vogelia indica, I ribson : Wight Ic. t. 1075. Sind, Ra.jputana. dry districts of the 

 Northern Deccan. A shrub with long brandies. 1. alternate, entire, amplexicaul or 



perfoliate. Fl. in spikes arranged in terminal panicles. Calyx deeply 5-fid. broad trans- 

 versely undulate wings between the ribs, style filiform, with 5 stigmatose branches. 

 Capsule included in the calyx, circumsciss at the base. 



Order LXVII. MYRSINACEjE. Gen. PI. ii. 639 (Myrsinece). 



(Mez, Myrsinacece, iu Engler's Pflanzenreich, 1902.) 



Shrubs or small trees. L. alternate, undivided, generally gland-dotted, 

 stipules 0. PI. bisexual or polygamous, usually 5-merous, calyx persistent, 

 often enlarged in fr. Corolla-tube short or none, segments (petals) contorted 

 or imbricate. Stamens opposite the corolla-lobes, and frequently adnate to 

 them, anthers usually dehiscing by longitudinal slits. Ovary 1-celled, narrowed 

 into the stjde, ovules inserted on a free central placenta. Embryo transverse 

 in copious albumeu. 



Resin cavities and resin duels are found in the leaves, pith, w 1 and bark. The 



account given in Gamble's [ndian Timbers ed, Li. 138 \4Q ot Myrsine africana, capi- 

 leVoin and U/mbelia robusta, nuke-, ii probable thai these species have resin cavities or 

 special cells filled with resin in the medullary rays, analogous to the wood oil in the 

 ra ys of Dipt-erocorpus alatus (p. 64, 66),
