CoRDiA ASPERA (Forst.) : pube ferruginea hirsuta, demum glabres- 

 cens ; foliis merabranaceis ovatis acuminatis asperulis supra glabratis, 

 serraturis subulatis ; floribus parvis cymoso-glomeratis ; calyce ovato- 

 cylindraceo ferrugineo-villoso 10-striato, dentibus 5 minimis subulatis ; 

 corollas tubo calycem vix superante lobis £estivatione inflexis et cor- 

 rugatis longiore ; drupa ovata acuta nuda, putamine 1 - 2-spermo. — 

 Tonga, Feejee, Samoan, and some of the Coral Islands. A distinct 

 and genuine Gordia, but the specific name is unfortunate, for the 

 leaves are by no means rough. — This is no. 336 of the Feejee collec- 

 tion of Dr. Seemann, referred by him to G. Sprengelii, DC, but it 

 does not accord with Sprengel's detailed description. 



Lahiatce. 



Gardoquia PiLOSA (sp. nov.) : fruticosa; foliis lato- seu rhombeo- 

 ovatis petiolatis subserratis lineato-venosis baud coriaceis puberulis 

 subtus vix canescentibus ; verticillastris multifloris ; calycis hirsuti 

 pedicello longioris dentibus subulatis, fauce ' intus nuda ; corollis " coc- 

 cineis " pilosis calyce (semipollicari) triplo longioribus. — Andes of 

 Peru at BaSios. Resembles G. rugosa in the foliage, but the flowers 

 are much larger, the corolla elongated, &c. It needs to be compared 

 with G. pulchella, H. B. K. ; but the branches are glabrous, and the 

 leaves not tomentose beneath, nor coriaceous. 



Sphacele hastata (sp. nov.): herbacea; foliis amplis hastatis 

 creberrime crenulatis utrinque cauleque cano-tomentulosis, floralibus 

 oblongo-lanceolatis sessilibus ; cymis laxis mvdtifloris thyrsum elon- 

 gatum efficientibus ; corollis " purpureis " tubulosis calyce triplo longiori-

crustacere. Embryo generis, i. e. cotyledones plance, integrse. C. dichoto- 

 MA, Lehm. C. (Galapagoa, Hook, f.) Darwini & fusca. 



5. TiQuiLiopsis. CoroUffi tubus basi intus 5-squamatus. Nuculse fere mem- 



branaceEe. Cotyledones bipartitse, radiculas utrinque accumbentes. Cset. 

 Tiquilice. C. Ndttallii, Hook. Kew Jour. Bot. 3, p. 296. Tiquilia parvi- 

 folia, Nutt. in herb. Hook. T. hrevifolia, Nutt. herb, ex Torr. Bot. Mex. 

 Bound., p. 136. T. Oregona, Torr. Bot. S. Pacif. Exped. (Calif. & Oregon), 1. 12. 



Ptilocaltx, Torr. in Pacif. K. R. Rep. 1. c, t. 8, where it is admirably figured, 

 may be regarded as a Stegnocarpus, with all but one of the cells of the ovary sterilcj 

 these appearing as lateral vestiges on the cross-section of the monococcous cori- 

 aceous fruit. In this view it is not likely to stand as a genus, unless Tiquilia also 

 does. Those who regard the reduction here foreshadowed as too great, might be 

 better satisfied with three genera, viz. Coldenia, Ptilocalyx, and Tiquilia.
