“ Eleagnus spadicea : foliis ovato-lanceolatis subundulatis, subtus le- 
pidoto-spadiceis, ramis spinescentibus, floribus axillaribus solitariis 
pedunculatis.” ‘This plant was contained in the catalogue of Burdin, 
seedsman in Turin, under the name of Capparis Breynii.—** Cornac- 
chinia = Syst. sex: Didynamia Gymnospermia = Fam. Nat. Verbe- 
nacesze.—Calyx monosepalus, persistens, subirregulariter quinque- 
fidus. Corolla hypocrateriformis, tubo elongato gracili, /émbo patente, 
subirregulariter quinquelobo. Stamina quatuor, longe exserta, quo- 
rum duo paullo breviora. Anthere ovales. Stylus staminibus longior, 
filiformis, stigmate acuto bifido. Ovartum liberum. Fructus Cap- 
sula subglobosa lignosa, sarcocarpo suberoso rimoso in lobulos pro- 
minulos obtusos irregulares oblongos discriminato, sulcis duobus, 
versus apicem, normaliter intersectis notata; bilocularis (abortu 
unilocularis); bivalvis, valvis maturis ad medium usque bifidis? 
Dehiscentia septicida. Troposphermum lignosum, dissepimento du- 
plici adnatum utrinque concavum. Semina duo (altero abortiente) 
unum in quavis cavitate trophospermi, ejusque margini prope 
apice suspensum. Testa membranacea. Hmbryo aperispermicus, 
orthotropus.—Sp. unica: Cornacchinia fragiformis, Habitat secus 
ripam occidentalem Nili in Nubia, prope Abdelherim (?), ubi Erg- 
Elmena vocatur.” It was collected by the late Sig. Raddi. 
Thirty-six notes are appended to the catalogue of Egyptian plants, 
in which species already known are explained, or new species provided 
with diagnoses. The latter are here reprinted. =No. 10. ‘* Aristida 
Raddiana : foliis convolutis recurvis rigidis ad faucem vaginee ciliatis, 
culmo pilosiusculo, panicula racemosa, valvulis ineequalibus acumi- 
natis, arista articulata tripartita, lacinia media majore unica plumosa 
apice nuda, calycis longitudinem quadruplam vix subzquante.” 
New diagnoses are given for the following species: ‘Aristida ciliata, 
plumosa, capensis, pungens ; and for Acacia vera, Seyal, Raddiana and 
albida.—Coronopus Raddii: fructibus compressis subcymbeeformibus 
glabris tuberculato-rugosis, foliis spathulato-dentatis, caule patulo.”’ 
—Ruta glabra and Ruta tuberculata, Viv. pl. eg. decad. are made 
synonyms with his R. ciliata, to which the following diagnosis is 
assigned : pilosa v. glabriuscula, foliis integris, inferioribus obovato- 
spathulatis, vel lanceolato-obtusis, superioribus lanceolatis, subtus, 
caulibus, capsulisque tuberculato-glandulosis, corymbis dichotomis, 
calyce minimo, filamentis ciliatis. From the notes we select the fol- 
lowing. Savi’s Scirpus lateralis is Sc. supinus, Roth.; his Cyperus 
paliidus is synonymous with C. Tenori, Presl. and Bertol., and C. 
Tenorianus, R. Sch.—The genus Polypogon, Desf. (1800) was al- 
ready established in 1798 in the eighth volume of these Memoirs, 
under the name of Santia, by Savi. Aristida ascensionis is declared 
to be not different from A. cerulescens. His Poa ramosa (Mem. d. 
Soc. Ital., tom. ix. tav. 7.) is Calotheca repens. These three me- 
moirs are followed by a short notice on Acacia bimucronata, DC., 
which after examination of perfect specimens of the fruit brought by 
Raddi from Brazil, is declared to be a true Mimosa. Of the two 
plates, one represents H/eagn. spadicea, the other Cornacchinia fra- 
giformis.
