Obder CXXIII. GARRYACE^. 
GARRYACEiE, Liudl. iuBot. Regist. 20. t. 1686. (July 1834). 
Essential Character. — Flowers unisexual (dioecious). Males: Calyx 4-leaved. 
Stamens 4, not elastic. Females : Calyx superior, two-toothed. Ovary one-celled ; styles 
2, setaceous ; ovules 2, pendulous, with funiculi as long as themselves. Pericarp berried, 
indehiscent, two seeded. Embryo very minute, in the base of fleshy albumen. — A shrub. 
Leaves opposite, without stipules. Flowers arranged in pendulous amentaceous racemes, 
within connate bracts. Wood without distinct concentric zones, or vasiform tissue (dotted 
ducts) . 
Affinities. Of this curious type of structure only one genus and one 
species have been discovered, concerning which the following observations will 
be found in the Botanical Register, in the place above referred to. 
“ In its amentaceous inflorescence, imperfect flowers, superior calyx, and 
mode of germination, Garrya is very similar to Cupuliferee, from which it diflers 
most essentially in its wood without concentric circles, or vasiform tissue 
(dotted vessels), its opposite exstipulate leaves, simple fruit, and minute 
embryo lying in a great mass of albumen. The latter characters bring it near 
Piperaceee and their allies, especially Chloranthacece, with which its zoneless 
wood (for Chloranthus has no annual zones), simple fruit, and opposite leaves, 
also agree ; but the stipules of Chloranthaceee, together with its naked bisexual 
flowers, and articulated stems, distinctly separate that order. Urticacew and 
StilaginaceeB may also be compared with Garrya on account of their imperfect 
unisexual flowers, somewhat amentaceous inflorescence, and simple fruit ; but 
their superior fruit, alternate leaves, and more perfectly foraied wood, are im- 
portant points of difference. Gnetacece may also be compared to Garrya on 
account of their opposite exstipulate leaves, amentaceous unisexual flowers 
appearing from the axils of connate bracts, their minute embryo lying in a 
great mass of albumen, and imperfect zoneless wood, which in both cases is 
chiefly constituted of woody fibre (the sides of which are marked with nume- 
rous brownish granules), and of annular and reticulated vessels lying scattered 
sparingly among the tubes of woody fibre. Finally, Henslovia, an imperfectly 
known genus, with regularly zoned wood filled with dotted ducts, like those of 
Ulmus, is not to be overlooked in comparing Garrya with other genera, on 
account of its imperfect unisexual flowers and opposite exstipulate leaves ; but 
the natural order {Hensloviacew) , of which it must be considered the type, is 
too little known to enable us to carry the comparison further.”

Order CXXIV. HENSLOVIACE^. 
HENSLOviACEiE, Liudl. in Bot. Reg. 20. fol. 1686. (July 1834) ; Martius Conspectus, 
No. 11. (1835). 
Essential Character. — Floivers unisexual (dioecious). Calyx b- parted, lined with a 
woolly disk, [with a valvate sestivation. Males : Stamens 5, alternate with the sepals, 
perigynous, long, exserted, indexed in gestivation, Griffith in litt.'] ; anthers 2-celled, with a
