had previously been published by other authors; occasionally, 
his identification is considered wrong. Thus Cype7’us procerus 
Roxb. is distributed by Clarke * between Cyperus malaccensis 
Lam., Pycreus puncticulatus Nees, and (herbarium only) Cypei'us 
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. p^'ocei'us.^ 
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, Bnicea sumatrana, Dracaena angustifolia, Garuga pin- 
nata, Bergia ammannioides, Sterculia guttata, Ficus Tsiela, 
Sapium sebiferum, and Calamus latifolius. Morinda b^'acteata 
is also unaffected, but there is grave doubt as to its value as a 
species. But Ficus I'acemifei'a Roxb. replaces F. variegata Bl. 
Metrosidei'os vera and Gmelina ai’borea 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 
amai'a, Plade^^a virgata, Pladera pusilla, Scaevola Taccada, 
Cordia campanulata, Vitis latifolia, Heliconia buccinata, Achy- 
ranthes triandra, Asclepias pseudosarsa, Asclepias odoratissima, 
Panax conchifolium, Cidnum Toxica^'um, Curculigo sumaDana, 
Yucca superba, Leersia aristata, Polygonum, rivulare, Caesalpinia 
paniculata, Jussiaea exaltata, Diospy7-os Sapota, Calophyllum 
Bintagor, Ajuga disticha, Ajuga fTruticosa, Plect7'anthus strobili- 
ferus, Ruellia zeylanica, Volkamc7da info7dunata, Columnea 
balsamica, Modecca tuberosa, Hibiscus tortuosus, Ca7'popogon 
giganteum, Dolichos vh^osus, Aeschynomene spinulosa, Hedy- 
sarum Neli-tali, Melaleuca Cajuputi, Serratula anthelmentica, 
Serratula cinerea. Arum viviparium. Arum, gracile, Urtica ten- 
acissima, Sague7ms Rumphii, Phyllanthus Leucopyrus, B7'adleia 
multilocularis, B7'adleia pinnata, Ophioglossum filiforme. Poly- 
podium excavatum, Ptc7ds scandens, and Eranthemum montanum. 
The remaining thirty-two cases all require comment, some of
