 hairs on both faces ; petiole slender, more than half as long as the leaf. Stipules 

 6-7 lin. long. Inflorescences : male not seen ; female consisting of a small

4. LAPORTEA, Gaud. ; Benth. et Hook. f. Gen. PI. iii. 383. 



Flowers monoecious or dioecious in cymose clusters in a branched 

 paniculate inflorescence. Male flowers : Perianth divided into 4 to 

 5 ovate segments, bud depressed. Stamens 4 or 5 ; ovary rudi- 

 mentary. Female flowers : Perianth of 4 more or less unequal 

 imbricate segments. Ovar}^ soon becoming oblique ; stigma linear, 

 ultimately reflexed and persistent ; ovule erect from the base. Achene 

 very oblique, compressed, the lower portion partly covered with the 

 persistent unchanged perianth. Seed conforming to the mem- 

 branous pericarp ; albumen very scanty ; cotyledons broad. — 

 Perennial herbs, shrubs or trees, generally beset with stinging hairs. 

 Leaves alternate, petioled, generally toothed, 3-nerved at the base 

 with a few ascending lateral nerves above ; cystoliths dot-like. 

 Stipules more or less united into a single intrapetiolar structure, 

 deciduous. Inflorescences solitary, axillary, unisexual. 



Species about 25, widely distributed through the warmer regions of the Old 

 World ; a few in North and Central America. 



This genus is very near to Fleurya ; it is distinguished by its perennial habit 

 and dot-like cystoliths.
