Nach einigen Bemerkungen über das Verhältniss von cultivirten 

 und wildwachsenden Pfhinzen in der Flora des Elsass entwirft Verf. 

 eine kurze Schilderung der charakteristischen Elemente der Hoch-

 skizzirt kurz die Gründe, welche für die Eigenthümlichkeit und Ver- 

 schiedenheit dieser H o c h v oge sen - Flora massgebend sind.

The first of a series of „Sketches of Vegetation at Home and 

 Abroad". The authors have on the southern coasts of Ceylon foUowed 

 up S ch i m p er 's work on indo-malayan Strand-Vegetation. The chief for- 

 mations are the Pes-caprae and the Barringtonia on sandy shores, and 

 the mangrove and the Semi-mangrove in tidal estuaries with mud. Good 

 descriptions are given of the prominent features of the above forms of 

 Vegetation. 'Ihe more important plants are also described and in many 

 cases figured. The Pes-caprae formation is limited to the sandy Strands, 

 between high-tide mark and a steep bank on which (in this part of 

 Ceylon) coco-nut plantations almost entirely suppress the natural 

 Barringtonia formation. An outer and an inner zone of the Pes-caprae 

 formation may be distinguished on broad gently sloping Strands. The 

 outer consists of Ipomaea biloba (Pes-caprae), Zoysia pungens, Reniirca 

 maritima, and other plants with a creeping habit^ acting as sand-binders 

 and covering the ground imperfectly; the inner zone is a continuous 

 carpet of Vegetation in which tufted species (Criniim asiaticum, Pan- 

 cratium zeylanicum, Crotalaria nana, etc.) find a place. Fresh-water 

 pools in the sand harbour an abundant growth of Nostoc and other 

 Cyanophyceae, which prepare the sand for the growth of higher plants. 

 The mangrove formation on tidal mud of estuaries is dealt with, and its 

 characteristic features are shown in a series of sketches. The principai 

 genera, Rhizophora and Brugiera, are fully described, as well as 

 Sonneratia acida, Acantfius ilicifolins, Avicennia officinalis, and other 

 plants which show interesting adaptations for life under mangrove con- 

 ditions. Certain red algae (Delesseria, Nemalion, Polysiphonia) and 

 green algae were found to be characteristic forms on the roots and pneu- 

 matophores of the mangroves. Where the conditions do not suit the 

 typical mangrove formation, a semi-mangrove or semi-halophyte Vege- 

 tation occurs. This the authors regard as too mixed to be designated
