ROBINSON. 



had previously been published by other authors; occasionally, 

 his identification is considered wrong. Thus Cyperus procerus 

 Roxb. is distributed by Clarke 8 between Cyperus malaccensis 

 Lam., Pycreus puncticulatus Nees, and (herbarium only) Cyperus 

 tuberosus Rottb. But if Cyperus procerus Roxb. be considered 

 as described in the Hortus Bengalensis, it is by the citation of 

 Rheede's Hortus Malabaricus 12: pi. 50, which according to 

 Clarke would identify it with C. malaccensis Lam. However, 

 there is an older C. procerus. 9 



Returning to the ninety-one names published in the Hortus 

 Bengalensis, investigation shows that the priority of singularly 

 few is changed by the throwing back of the date of publication. 

 On the other hand, the new means of typifying them raises or 

 solves many intricate problems. These will briefly be stated. 



The following remain unchanged as good species : Oldenlandia 

 diffusa, Brucea sumatrana, Dracaena angustifolia, Garuga pin- 

 nata, Bergia ammannioides, Sterculia guttata, Ficus Tsiela, 

 Sapium sebiferum, and Calamus latifolius. Morinda bracteata 

 is also unaffected, but there is grave doubt as to its value as a 

 species. But Ficus racemifera Roxb. replaces F. variegata Bl. 

 Metrosideros vera and Gmelina arbor ea are to be credited to 

 Roxburgh, instead of to Lindley and Linnaeus, respectively. 



Half of the names have no importance except as synonyms, 

 except that a few, with unaltered status, form the basis for 

 generally accepted binomials. The synonyms are: Gratiola 

 amara, Pladera virgata, Pladera pusilla, Scaevola Taccada, 

 Cordia campanulata, Vitis latifolia, Heliconia buccinata, Achy- 

 ranthes triandra, Asclepias pseudosarsa, Asclepias odoratissima, 

 Panax conchifolium, Crinum Toxicarum, Curculigo sumatrana, 

 Yucca superba, Leersia aristata, Polygonum rivulare, Caesalpinia 

 paniculata, Jussiaea exaltata, Diospyros Sapota, Calophyllum 

 Bintagor, A jug a disticha, Ajuga fruticosa, Plectranthus strobili- 

 ferus, Ruellia zeylanica, Volkameria infortunata, Columnea 

 balsamica, Modecca tuberosa, Hibiscus tortuosus, Carpopogon 

 giganteum, Dolichos virosus, Aeschynomene spinulosa, Hedy- 

 sarum Neli-tali, Melaleuca Cajuputi, Serratula anthelmentica, 

 Serratula cinerea, Arum viviparium, Arum gracile, Urtica ten- 

 acissima, Saguerus Rumphii, Phyllanthus Leucopyrus, Bradleia 

 multilocularis, Bradleia pinnata, Ophioglossum filiforme, Poly- 

 podium excavatum, Pteris scandens, and Eranthemum montanum. 



The remaining thirty-two cases all require comment, some of
