Leprieurii, P. australis, P. senex, P. Hasskarlii, Trametes occidentalis, 
Hexagonia polygramma, Stereum Bonjanum, S. lobatum ; all obtained 
by Mr. Armit. Algs : Sargassum decurrens, Cystophyllum muricatum, 
Turbinaria vulgaris, Cbneospora obtusangula, Hydroclatbrus cancellatus, 
Vidalia pumila, Amansia glomerata, Acanthophora dendroides, Desmia 
ambigua, Gracilaria lichenoides, Sarcodia palmata, Hypnea hanmlosa, 
H. seticulosa, Phycoseris reticulata, CliEetomorpha valida. These 
cryptogamic plants were named by the following renowned specialists 
respectively : Dr. C. Mueller, Dr. J. Mueller, Dr. M. C. Cooke, Dr. W. 
Sender. New Guinea ought to yield us thousands of evascular crypto- 
grams from its lowlands j ungles up to its alpine summits. 
The following genera of plants are now known to be represented 
also in New Guinea, irrespective of those mentioned in the Malesia 
and in the present work ; but the Papuan species so far have as yet 
not been defined from the mostly imperfect material available : Oxymitra, 
Chloranthus, Busbequea, Crataeva, Schuurmansia, Sterculia, Triumfetta, 
Hopea, Vateria, Antidesma, Omalanthus, Elatostemma, Cudrania, 
Celastrus, Samadera, Spondias, Mollugo, Salicornia, Alysicarpus, 
Cajanus, Uraria, Pueraria, Strongylodon, Lagerstrcemia, Nauclea, 
Lasianthus, Modccca, Hodgsonia, Cucumis, Agapetes, Labisia, Ardisia, 
Diospyros, Strychnos, Melodinus, Graptophyllum, Buechnera, Spato- 
glottis, Habenaria, Smilax, Monochoria, Scirpodendron, Hypelythrum, 
Sporobolus, Cyathea, Alsophila, Hypolepis, Spiridens. Several of these 
were first mentioned as Papuan by Dr. Beccari in D’Albertis’s New 
Guinea ii. 396-400, where also additional notes on Palms are given. 
Of many of the genera, previously recorded, now additional species are 
known, often however only in a state insufficient for exact examination. 
The six parts of Dr. Beccari’s splendid “ Malesia,” issued between 
1877 and 1884, contain accounts of plants belonging to the orders of 
Magnoliaceffi, Monimiaceaj, Myristicacese, Nepenthaceae, Violacese, 
Chailletiacese, Euphorbiacea;, Olacinae, Araliaceae, Rubiaceae, Ericaceae, 
Coniferaa, Cycadese, Burmanniaccaa, Aroidae and Palmae — Papuan 
species being described along with others from the Sunda-Islands, often 
extensively and connectedly. 
On coxmting up, what is known now of the Papuan vegetation with 
specific exactitude, it will be found, that about 1,000 species stand as
