HENDERSON'S HANDBOOK OF PLANTS. 



CAT 



ones, or sepals, firmly cohering at the 

 tips, are carried upward by the anthers 

 as the filament is produced. The female 

 flowers are in dense axillary heads with- 

 out any perianth. The ovaries, sessile 

 within the bracts of the head, are 

 one-celled, with a single ascending ovule, 

 and bear two styles united at the base ; 

 the winged nuts are collected in a cone 

 hidden under the thickened bracts. The 

 Casuarinas are natives of Australia, New 

 Caledonia, and the Indian Archipelago. 



Cataclesium. A one-celled, one-seeded 

 fruit inclosed within a hardened calyx, 

 as in Mirabilis. 



Catapetalous. Having the petals slightly 

 united by their inner edge near the base, 

 as in the Mallow. A form of polypeta- 

 lous, which see. 



Catemdate. Formed of parts united end to 

 end, like the links of a chain. 



Catkin. A deciduous spike, consisting of 

 unisexual apetalous flowers; an amen- 

 tum, which see. The flowers of the Wil- 

 low, Hazel, etc., are Catkins. 



Catidus. A catkin or amentum, which see. 



Cauda. Any long, soft, narrow terminal 

 appendage resembling a tail, as that of 

 the corolline lobes of Strophanthus or the 

 lateral sepals of Cypripedium caudatum. 



Caudatus, Caudate. Tailed, or having a 

 long terminal appendage. See Cauda. 



Caudex. The axis of a plant, consisting of 

 the stem and root. Applied also to the 

 trunk of Palms and Tree Ferns. Caudex 

 repens is a creeping stem, or what is 

 now called a rhizome. Caudex descendens 

 is the root 



Caudicula. The cartilaginous strap which 

 connects certain kinds of pollen masses 

 to the stigma, as in Maxillaria. 



Caulescent. Acquiring a stem. 



Caulicle.A. portion of the axis intermedi- 



CED 



ate in structure and position between 

 the true root and stem, and called the 

 hypocotyledoiiary axis; the space between 

 the radicle and cotyledons. 

 I Caulicule. The little stem of the embryo 

 which unites the cotyledons with the rad- 

 icle. 



Caidigenous. Arising from a stem. 



Cauline. rOf or belonging to the stem. 

 Cauline stipules are such as adhere to the 

 stem as much as to the petiole or leaf. 



Caulis. The stem or ascending axis; a 

 name given only to the part in its cus- 

 tomary state, growing in the air. Caulis 

 deliquescens, a stem which at a distance 

 above the earth breaks into irregular 

 ramifications, as in the Oak. Caulis ex- 

 currens, a stem which shoots straight 

 from the ground to the summit, having 

 branches on the sides, as in Abies. 

 \ Caulocarpous. A stem which Lives many 

 years, repeatedly bearing flowers and 

 fruit; as a shrub or tree. 



Cauloma, The stem of a Palm Tree; the 

 stem-like portion of the thallus (which 

 see) of such Algce as some Fuci. 



Caulon. In Greek words equivalent to 

 stem. 



Cavernuli. The pores of certain Fungi. 



Cavus. Hollow, full of holes. The peridi- 

 um (which see) of certain Fungi. Cavus 

 superus is the hymenium (which see) of 

 certain Fungi. 



Cedrelacece, ( Cedrelads, the Mahogany family. ) 

 A natural order of Thalamifloral Dico- 

 tyledons belonging to Lindley's Rutal 

 Alliance. The order consists of trees 

 with alternate pinnate leaves, without 

 stipules. The flowers in panicles; the 

 calyx four to five cleft; the petals four to 

 five; the stamens eight to ten, inserted on 

 a disk, ..The ovary is three to five celled. 

 The fr*ut>. is, a capsule opening by valves,
