ALGACITES

(Lat.), n.f. pl. A°l(a°1)-ga3-si(ke)tez(te?s), Fr, algacites, Ger., Algaciten. An order of fo il plants, established by Sternberg, corresponding to the extant Algæ, including the subgays Confervoid i tes, Ulvoidites, Floridoites, and Fucoid i tes. [B, ALGÆ (Lat.), n. f. pl. 'je(ga%-e?). Fr., algues. Ger., Algen, Tange. It., alghe. Sp., algas. Syn.: hydrophytes, Hydropigte yngbye]. In Linnæus's system, an order of the cla Cryplogamia, comprising at first genera now ranked among the À, Lichenes, and Hepaticæ. In Ju ieu’s cla ification, the A. embraced the true À. (4. aquaticee) and the Lichenes (A, terrestres). In the modern systems, the sea-weeds, a great division of crypto- ‘ams, Coe those plants of this section in which there is no if fer entia tion into axis, root, and appermPars (thallogens), but which are provided with chlorophyll and with distinct organs of reproduction, being thus distinguished from the Protophyta on the one hand and from the Fungi on the other. By many, the A. and the chlorophyll a ceo us Protophyta are grouped together (vide infra), and some include both A. and F'ungi under one section as Thallophyta (q. v.). By others, again, the division is entirely abandoned, and members formerly included in this cla are now grou] with the allied Fungi under quite distinct divisions of the vegetable kingdom. See CARPOSPOREÆ, OOSPOREÆ, PROTOPHYTA, and ZYGOSPOREÆ, The A. have been variously subdivided. The two main systems of cla ification at present in vogue are based respectively on the mode of reproduction and on the color of the spores. According to the former, the A. like the Fungi are divided into Zygosporeæ, ornare and Carposporeæ (q. v.); according to the latter, into Chlorospermeæ, Mélanospermeæ, and Rhodospermeæ [Berkeley]. The following table shows the equivalence of these two systems: A. ZYGOSPOREÆ. Zoosporeæ. }(Diatam,aœœ.) CHLOROSPERMEÆ (in- Conjugatæ. Oosïgo cluding also n-
