and Miscellaneous Particulars. 
1937. Ceratocarpus. Named from xi^ai, a horn, and jjotao'o?, fruit, because the seeds have two horns. 
Useless weeds. 
1938. Zannichellia. So called in honor of John Jerome Zannichella, a Venetian apothecary, who died in 
1729. He left behind him a few works of little consequence. A plant found abundantly in the marshes of 
some parts of England. 
1939. Lenina. Said to have been so called from Xi^i;, a scale, in allusion to the form of the plants. Theo- 
phrastus describes under the same name an aquatic plant. Annual weeds, which float on stagnant water, 
their flowers are very obscure, and not produced freely in northern climates. L. trisulca has dichotomous, 
filiform, divaricated stems, having a lanceolate leaf at the angle of the branches, but proliferous ones termi- 
nating the branches ; where these leaves are conjoined, there shoots out a pendant radicle, with a conical 
papilla at its base. Linnseus observes, that the stems are flatted and proliferous, crossing each other, and thus 
resembling in the mode of growth the opuntia or Indian fig. The leaves of L. minor are very small, of a 
roundish ovate form, collected into heaps by twos or threes, and forming extensive green plats on stagnant 
waters; each leaf drops a single radicle. This plant affords nourishment not only to ducks, but to the fresh 
water polype, to Phalcena Lemnata, &c. Its quick and extensive propagation makes it troublesome in some 
cases, but at the same time it is considered valuable as converting hydrogen gas into air adapted to respiration. 
L. polyrhiza is distinguished by its dropping bundles of thick black fibres from the lower surface of the 
leaves. The plants sink in the water in the winter season, and either these or new ones appear again in the 
spring. 
1940. Anguria. One of the Greek names for the Cucumber. The plant now so called is also a kind of gourd. 
The species grow freely on light soil, and are propagated by seeds or roots. 
1941. Comptonia. Named in honor of Henry Compton, Lord Bishop of London, by whom the fine collection 
of plants attached to the episcopal palace at Fulham was formed. A handsome shrub, which thrives in peat 
soil, or sandy loam, and is increased by suckers or layers. 
1942. Hernandia. So called in honor of Francisco Hernandez, a Spanish botanist, and first physician to 
Philip the second of Spain, by whom he was sent to Mexico for the sake of investigating the natural history of 
that country. Linnteus is said to have named it in allusion to the large leaves and little flowers of the i)lant, 
which may be supposed to represent the great means and small advantages which attended the expedition 
of Hernandez. This is an upright lofty tree, with an elegant head. The fruit is a nut, sustained and partly 
enveloped by a yellow persisting calyx. The nuts are very large, and as they move in the wind, produce sound 
enough to alarm unwary travellers. In our stoves the plants grow freely in loamy soil, and ripened cuttings, 
with their leaves on, root in sand under a hand-glass. 
1943. Axyris. A word of unknown meaning. Plants of little beauty and the easiest culture.
