edges, and the seeds are enveloped in a 

 sweet, generally white pulp. 



I. FeuiUei, a native of Peru, is cultivated 

 in the gardens about Lima, where the in- 

 habitants call it Pacay, and commonly eat 

 the white pulp of its pods. Its leaves have 

 winged stalks, and are composed of three 

 or four pairs of oval-oblong leaflets, which 

 are smooth, and tapered towards both 

 ends. Its pods are sometimes as much as 

 two feet long. 



I. spectabilis is a large showy tree, called 

 Guavo real in the Isthmus of Panama, 

 where it is commonly cultivated on ac- 

 count of its eatable pods, as it also is in 

 some parts of New Grenada. The leaves 

 consist of two pairs of smooth and shin- 

 ing, egg-shaped, pointed leaflets, the upper 

 pair being much the largest. The flowers 

 are pure white, succeeded by numerous 

 large pods, two or more feet long, and 

 three inches broad, which, in consequence 

 of their weight, are pendulous from the 

 branches. The white pulp surrounding the 

 seeds in the pods of this and other species 

 of the genus, has a pleasant sweet flavour, 

 and is much eaten by the inhabitants of 

 Panama. 



I. vera, a "West Indian tree, common in 

 Jamaica and Trinidad, has leaves with 

 winged stalks, and four «r five pairs of 

 elliptical lance-shaped leaflets. Its pods 

 are curved like a reaper's sickle, and mea- 

 sure about six inches long ; the pulp con- 

 tained in these is sweet, but like that of 

 several other species, it possesses purga- 

 tive properties. [A. S.] 



INGENHOUZIA. A name applied to a 

 Mexican shrub, described as being like a 

 Gos.vjpium, and with yellow flowers, pass- 

 ing into red, and numerous stamens in one 

 parcel. It is not perfectly known, but is 

 evidently allied to the Malvaceae. [M. T. M.] 



INK-BERRY. An American name for 

 Prinos glaber. 



INNATE. Adhering to the apex of a 

 thing, as the anther to the apex of a fila- 

 ment. 



INNOVATIONS. A name given to the 

 new branches of mosses, which are pro- 

 duced after the fructification has been 

 perfected, or after the first complete 

 growth where the plants remain barren', j 

 A difference of habit may arise from their ! 

 suppression or peculiar growth. In Bryvm, ! 

 for example, the innovations are produced 

 from the floral apex, but in Leptobrynm j 

 none are produced. The little bud-like J 

 tufts which bear the male organs in some 

 species of Hvpnurn and Dicranum, which j 

 are attached very slightly to the stem, 

 must be distinguished from true innova- 1 

 tions. [M. J. B.] 



INOCARPUS. This genus consists of 

 hut one species, a larp-e tree, native of 

 Asia and the islands of the tropics, having j 

 alternate entire subcordate leaves, and 

 yellow flowers in axillary spikes. They 

 have a tubular calyx, arched at the back, 

 and bifid; five petals united to form al 



short tube; ten stamens in two rows, the 

 upper attached to the mouth of the corolla 

 tube and the lower to its base ; and a one- 

 celled ovary with a nearly sessile stigma. 

 The fruit is a fibrous pod with one seed. 

 The genus was for some time referred to 

 the daphnaceous family, its petals being 

 regarded as a calyx, but it is now known 

 to belong to Ccesalpiniecc, a section of the 

 leguminous family. The seeds of I. 

 edulis are much prized by the natives of 

 the Indian Archipelago, and in Machian 

 they almost live upon them. They are, 

 however, not palatable food, but when 

 boiled or roasted in ashes are sweet. They 

 are less agreeable than the chestnut, and 

 are not suited to weak stomachs. [B. C.] 



INOSCULATIO. The operation of graft- 

 ing or budding. 



INSECT FUNGI. Many animals are 

 subject to attacks of fungi, but none more 

 so than insects, whether in a perfect state 

 or in the condition of caterpillar or chry- 

 salis. Some of these fungi are very mi- 

 nute, and often of little interest except 

 from the ravages they commit amongst 

 bees, silkworms, &c. ; but others, on the 

 contrary, are large and sometimes bril- 

 liantly coloured, and attract notice from 

 the proportion which they bear to the in- 

 sect on which they grow. These belong to 

 the genus Cordiceps, to which head we re- 

 fer for particulars. Amongst them one of 

 the most remarkable is the species which 

 is so often brought home from New Zea- 

 land, where it is produced in abundance on 

 the caterpillar of Hepialus virescens. The 

 white mould which oozes out as it were 

 between the abdominal wings in autumn, 

 is in all probability a form of one of the 

 curious productions which we shall notice 

 under Saprolegnia. [M. J. B.] 



INSERTION. The manner in which one 

 part is inserted into or adheres to, or ori- 

 ginates from another. 



INTEGER. Properly speaking, this 

 means having no kind of marginal or other 

 division ; but sometimes it has been used 

 to indicate not pinnatifid, and also nearly 

 destitute of marginal division. 



INTEGERRIMUS. Perfectly free from 

 division of the margin or other part. 



INTEGRA VAGINA. A sheathing petiole 

 which forms a continuous tube, not slit on 

 one side, as in sedges. 



INTEGUMENTA FLORALIA. The ca- 

 lyx and corolla. 



INTER. In composition = between : as 

 inter foliaceits, placed between leaves. 



INTERCELLULAR. Anything inter- 

 posed between the cells or tubes of tissue. 



INTERMEDIUS. Standing between two 

 bodies in a different row, as petals when 

 they alternate with sepals. Also half-way 

 between one thing and another. 



INTERNODE. The space which inter- 

 venes between two nodes.
