Mirb. 19. Thrice digitato-pinnate († tridigitato-pinnatus, ternato-pinnatus); when the secondary petioles, on the sides of which the leaflets are attached, proceed in threes from the summit of a common petiole; as in Hoffmannseggia. Mirb. 20. † Quadridigitato-pinnatus, as in Mimosa pudica, and † Multidigitato-pinnatus, are rarely used, but are obvious modifications of the last. 21.

Biternate (biternatus, † duplicato-ternatus); when three secondary petioles proceed from the common petiole, and each bears three leaflets; as in Fumaria bulbosa, Imperatoria Ostruthium, &c. Mirb. 23. Triternate (triternatus); when the common petiole divides into three secondary petioles, which are each subdivided into three tertiary petioles, each of which bears three leaflets; as the leaf of Epimedium alpinum. 24. Tripinnate (tripinnatus); when the leaflets of a bipinnate leaf become themselves pinnate; as in Thalictrum minus, or Enanthe Phellandrium. 25. Paired (conjugatus, unijugus, † unijugatus); when the petiole of a pinnated leaf bears one pair of leaflets; as Zygophyllum Fabago. Bijugus is when it bears two pairs; as in Mimosa fagifolia trijugus, quadrijugus, quinquejugus, &c., are also employed when required. Multijugus is used when the number of pairs becomes very considerable; as in Orobus sylvaticus, Astragalus glycyphyllus. 26. Branched (ramosus); divided into many branches: if the divisions are small, we say ramulosus. 27. Somewhat branched (subramosus); having a slight tendency to branch. HH 28. Excurrent (excurrens); in which the axis remains always in the centre, all the other parts being regularly disposed round it; as the stem of Pinus Abies. 29. Much-branched (ramosissimus); branched in a great de gree. 30. Disappearing († deliquescens); branched, but so divided that the principal axis is lost trace of in the ramifications; as the head of an oak tree. 31. Dichotomous (dichotomus); having the divisions always in pairs; as the branches and inflorescence of Stellaria holostea: if they are in threes, we say trichotomus; as the stem of Mirabilis Jalapa. 32. Twin (didymus); growing in pairs, or divided into two equal parts; as the fruit of Galium. 33. Forked (furcatus); having long terminal lobes, like the prongs of a fork; as Ophioglossum pendulum. 34. Stellate (stellatus); divided into segments, radiating from a common centre; as the hairs of most malvaceous plants. 35. Jointed (articulatus); falling in pieces at the joints, or separating readily at the joints; as the pods of Ornithopus, the leaflets of Guilandina Bonduc: it is also applied to bodies having the appearance of being jointed; as the stem and leaves of Juncus articulatus. 36. Granular (granulatus); divided into little knobs or knots; as the roots of Saxifraga granulata. 37. Byssaceous († byssaceus); divided into very fine pieces, like wool; as the roots of some Agarics. 38. Tree-like (+ dendroides); divided at the top into a number of fine ramifications, so as to resemble the head of a tree; as Lycopodium dendroideum. 39. Brush-shaped († aspergilliformis); divided into several fine ramifications, so as to resemble the brush (aspergillus) used for sprinkling holy water in the ceremonies of the Catholic Church; as the stigmas of grasses. 40. Partitioned (loculosus, † septatus, † phragmiger); divided by internal partitions into cells; as the pith of the plant that produces the Chinese rice-paper. This is never applied to fruits. 41. Anastomosing (anastomozans); the ramifications of any thing which are united at the points where they come in contact are said to anastomose. The term is confined to veins. 42. Ruminate (ruminatus); when a hard body is pierced in various directions by narrow cavities filled with dry cellular matter; as the albumen of the nutmeg and the Anona. 43. Cancellate (+ cancellatus); when the parenchyma is wholly absent, and the veins alone remain, anastomosing and forming a kind of network; as the leaves of Hydrogeton fenestralis. 44. Perforated (pertusus); when irregular spaces are left open in the surface of any thing, so that it is pierced with holes ; as the leaves of Dracontium pertusum. 雞$0000 1. Rugose (rugosus); covered with reticulated lines, the spaces between which are convex; as the leaves of Sage. 2. Netted (reticulatus); covered with reticulated lines which project a little; as the under surface of the leaves of most Melastomas, the seeds of Geranium rotundifolium. 3. Half-netted († semireticulatus); when, of several layers of any thing, the outer one only is reticulated; as in the roots of Gladiolus communis. 4. Pitted (scrobiculatus); having numerous small shallow depressions or excavations; as the seed of Datisca cannabina, Passiflora, &c. 5.

Scarred (cicatrisatus); marked by the scars left by bodies that have fallen off: the stem, for instance, is scarred by the leaves that have fallen. 9. Ringed (annulatus); surrounded by elevated or depressed bands; as the roots of some plants, the cupulæ of several Oaks, &c. 10. Striated (striatus); marked by longitudinal lines; as the petals of Geranium striatum. 11. Lined (lineatus); the same as striatus. 12. Furrowed (sulcatus); marked by longitudinal channels; as the stem of Conium, of the Parsnep, of Spiræa Ulmaria, &c. 13.
