ScaoPHt/j.ARiNiE. Only six species iof this family occur,¡none of which are unpublished. .r, Obobanche compacta of ,Viviam was observed between Fezzan and Bornou. Of Coicvoj.vui.ace* there are five species, four of whioh belong to Bornou ; the fifth is an aquatic Ipomcea, found creeping on the borders of a sihall lake near Tiutuma. Possibly this plant may be Ipomcea- aquatica of Forskal, and consequently Convolvulus repens of Vahl, (symb. 1, p. 17.) I t is not, how ever,, ¡the plant so called by Linnaeus, which proves, as I have elsewhere ■stated,. (/Voi/r. hi. \ or. HolL 1 , p. 483.) to be Calystegia sepidm; nor does it belong to either of his synonymes* Our plant differs also frodi Vahl’s description of ]iis Convolvulus repens, in having constantly single-flowered peduncles, qM lenyqs(,whose posterior lobes are rather acute than obtuse, and are quite entire,,, I t is, probably, therefore, distinct; and I have named it Ipomcea Clappertoni*. Among the few Labiate, there is a species of Lavandula, possibly distinct from but very nearly related to L. multifida. It was found on the mountains pf Tarhona. Of R oragineje, the herbarium includes eleven species, the greater part of which were collected near Tripoli, and all of them belong to well established genera. ., ., ., ui 1’hi»!!- i.a<:k,k. Of this family two species of Anagallis occur in the collection, and of these A. caerulea was observed both near Tripoli and in Bornou. SAjfpLun V alekandi was also found near Tripoli, in Wady Sardalis in Fezzan,,and in Bornou. ... t 0 / Jdiqotyledonous, or even of all phsenogamous plants, S. valerandi'is perhaps the most widely diffused. It'is a very general plant in Europe, has been found in several parts of North Africa, in Dr. Oudney’s herbarium it is from ,Bornou, I have myself observed it at the Cape of Good Hope and in New South Wales, and it is also indigenous to North America. The geographical distribution of the genus Samolus is equally remarkable. At present eight species are known, of which S. Valerandi is the only one in* Ipomcea Clappertoni, glaberrima repens, fbliis sagittatis: lobis posticis acntinsculis lite- gemmis, pedunculis unifloris. digenous to Europe, or which, indeed, has been found in the northern hemisphere, except the nearly related S. ebracteatus of Cuba. All the other Bpecies belong to I the southern hemisphere, where S. Valerandi has also a very extern sive range. Of PLtiMBAaiNEAE, there are three species of Statice Tamnthema; for the latter name may be preserved as belonging to a section, though hardly as that of a genus, so far at least as depends on inflorescence, which in both subdivisions of Statice is essentially similar; that of Statice Armeria being only more condensed. Of the three species in the herbarium, one appears to be unpublished. Among the plants of the Apetalous orders in the collection, there are very few ¡remarkable, and hardly any new species. Gymnocarpus deeaneb'um was observed by Dr. Oudney very commonly in gravelly deserts, on the route from Tripoli to Fezzan; and Coniulaca mona- canlha o f M. Delile is said to be widely extended from Tripoli to Bornou, and to be excellent food for camels. M o n o c o t y l e b o n e s . The number of species belonging to this primary division contained in the herbarium is altogether seventy. But Gramme® and Cyperaceae being excluded, thiiteen only remain, namely, three species of Junous, a single Commelina, three Melanthacete, three Asphodelese, one species of Iris, and two Aroideas, of which Pistia Stratiotes is one. Of these thirteen plants, two appear to be unpublished, both of them belonging to Melanthace*. The first, a congener of Melanthium pnnctatum, which is also in the collection, was found in Fezzan. The second is a species of Colckicum, very different from any hitherto described ; and which yet, by Mr. Ritchie, who first observed ifr is said to be common in the desert near Tripoli, where it was also found by Dr. Oudney. This species, which I have named Colchkum Ritchii, is easily distinguished from all its congeners by having two cristse or membranoas processes which are generally fimbriated, at the base of each segment of the pCrianthium, parallel to each other, and to the intermediate filament. But this character, though excellent as a specific difference, is neither of generic importance, nor sufficient to authorise the. formation of a separate section *. * Colchicum (^Hermodactylus) R itM i, limbi ladniis baai iatua bicristatis! fascicule 2- multi- noro, loins liiicorious.
