T HE calyx of the Protea is a common perianthium, of a roundifh figure, and imbricated ftrutture, formed of fquammre of a fomewhat oval fhape. The univerfal corolla is uniform, and is a little longer than the cup : the peculiar corolla is monopetalous : it's tube is of the length of the cup: it's limb is divided into four fegments, and is fmooth, patent, equal, and of the length of the tube. The fl:amina are four fetaceous filaments, and are longer than the flower : the antherre are incumbent: the germen of the piftil is of a roundilb figure: the ftyle is fetaceous and erect; the length of it is the fame with that of the fiamina : the fiigma is obtufe. There is no pericarpium : the calyx remains ~naltered,. and contains the feeds, which are fingle, roundifh, and naked: the receptacle IS of a comc figure, and feparated by palere. Boerhaave defcribes this genus under · the name of Conocarpodendron; Tournefort, after Plukenet, calls it Leucodendros; and Commelin, Argyrodendros: Ray, Conophoros. 1. Protea joliis angujlis rigidis, apicibus integris. .ne narrow, rigid-leaved Protea, with undivided extremities. The root of this fpecies is compofed of a number of thick and varioufly extended ramifications. The trunk rifes fingle, four inches in diameter, and covered with a yellowilb bark, rough and full of cracks. From the trunk there rife a number of branches, :obuft and !hick, and varioufly div!ded into others : in the whole it grows to about etght feet htgh. The leaves ftand Irregularly, and not thick together; they a!e. long, narrow, and much refernl:;le thofe of the common willow, but that they are ngtd to the touch : they are of a blue-gre~I: colour, but the middle rib is yellow. There grow clufl:ers of leaves at the extremities of the branches which· form a kind of circular con_geries, fr~£? the center of whi~h rifes a conic head, of the bigne[s of a cone of the lanx, contammg the flowers, whtch are very fmall and of which fcarcely any thing but the fiamina appear. . ) T~is fpecies is frequent about ~he Cape of Good Hope~ Sherard, in Ray's Hifiory, calls 1fl:t, Scolymo 1 c~p~alus olere foho.

At feveral different parts of the branches, among the leaves grow the cones ; they are fmall a~d fqual'nmofe, purplifh toward the fummit and yeliowifh toward the bafe. The flowers are fmall and yellow; they every-whe;e furround the furface of the cone. This fpecies g.r?ws a~u~dant_ly in. many. parts of Africa.

THE calyx of the Cephalanthus confi{ls of a common perianthium, which contains feveral flowers, collected into a kind of head, and of a proper perianthium, which is ereCt, permanent, and divided into four fegments. The corolla confifis of a fingle petal: the tube is flender: the limb is divided into four parts acute reflex and of the length of the tube. The fl:amina are four filaments, inferted into ~he cor;lla, and fhorter than it's limb; the antherre are fimple: the germen of the pifl:il is placed wlthin the ~o~cr: the fiyle and the fiigma are both fimple. The fruit is an oblong capfule, contammg only one cell: feveral of thefe grow together, and form a roundifh head. The feeds are numerous, and oblong: the flower has it's limb fometimes divided into five fegments; infiead of four, and then the proper perianthium has alfo five fegments, and there are five framina. Vaillant and Van Rheede call this genus, Platanocephalus; Petiver, Valerianoides. 1. Cephalanthus foliis oppojitis ternatifque. The Cephalanthus, with oppojite and ternate leaves. The root of this fpecies confifl:s of a number of ramifications, fpreading various ways under the fur face. The ll:em is firm and woody, and grows to a confiderable fize : the branches grow to a confiderable length: the bark is green; the wood reddilb, with fome yellowifh circles, and a greenifh heart: the leaves are oblong and broad,; they are of a bright green, narrow at the bafe, and terminate in a point at the extremity : they fiand ufually three together, furrounding the fialks; they are fomewhat rough to the touch, and of a bitter tafie. The flowers grow in clufl:ers, at the tops of the branches, and are of a yellowifh colour. !his fpecie~ is a native of North America; we have it in fome of our greenhoufes. Vaillant calls It, Platanocephalus foliis ex adverfo ternis; Petiver, Valerianoides Americana flore globofo, folio pifhaminis ; Plukenet, Scabiofa dendroides Americana ternis foliis. GLOBULAR lA. T H E common perianthium of the Globularia is imbricated, and of the length of · . . the flofcules : the proper perianthium is formed of a fingle leaf, tubulated, and dtvtded into fiye fegments at the extremity : the univerfal corolla is nearly equal : the ~roper corolla IS formed of a fingle petal, tubular at the bafe, and divided into four iegments at the edge; the upper fegment is fmall and reflex; the three lower ones are larger, eq?al in fize, and form a kind of lower lip. The fl:amina are four fimple fila~ e~ts,_ of the length of the corollula : the antherre are diftinct: the germen of the pt.!hl IS of an oval figure: the fl:yle is fimple, and of the length of the ftamina: the ihgma is obtufe : there is no pericarpium : the proper perianthium clofes at it's top, and contains the feed, which is fingle, and of an oval figure. The common receptacle is oblong, and divided by palere. _This genus comprehends the Globularia of Tournefort, &c. and the Alypum of N 1ffole and Dillenius. L 1 1 I. Globularia |
