RUMPHIUS'S HERBARIUM AMBOINENSE 



TECTONA * Linnaeus f. 



TECTONA GRAN DIS Linn. f. Suppl. (1781) 151. 



Tectona theka Lour. PI. Cochinch. (1790) 137. 



Jatus s. caju jati Rumph. Herb. Amb. 3: 34, t. 18. 

 Amboina, Binting, Robinson PI. Rumph. Amb. 298, July 29, 1913, on 

 open hillsides at low altitudes, locally known as jati. 



The teak tree is too well known to need discussion here. The 

 Rumphian description and figure are unmistakably Tectona 

 grandis, and the figure has been very generally cited by various 

 authors under one or the other of the synonyms listed above. 



The species is widely distributed in the Indo-Malayan region ; 

 in some countries it is very extensively cultivated. 



PREMNA Linnaeus 



PREMNA OBTUSIFOLIA R. Br. Prodr. (1810) 512. 



Premna cyclophylla Miq. PI. Ind. Bat. 2 (1858) 899? 

 Premna laevigata Miq. PI. Ind. Bat. 2 (1858) 895? 

 Premna integrifolia auct. plur. non Linn. 



Gumira litorea (G. silvestris) Rumph. Herb. Amb. 3: 209 t. 134, 

 Amboina, Robinson PI. Rumph. Amb. 307, August 8, 1913, along the 

 beach near the town of Amboina, locally known as gumira laut, that is, 

 gumira of the beach or ocean. 



The specimen cited above is unmistakably Gumira litorea 

 Rumph., as it agrees perfectly with his description and figure, 

 in its habitat, and in its native name, gumira laut. Its proper 

 name in our present system of classification is not so certain, 

 but it appears to me to be identical with Premna obtusifolia R. 

 Br., also a coastal shrub or small tree, of northeastern Australia ; 

 the two species described by Miquel, cited above as doubtful syn- 

 onyms; and the widely distributed coastal form in the Indo- 

 Malayan region that has very consistently, but erroneously, been 

 called Premna integrifolia Linn. The name "Folium hircinum" 

 of Rumphius, another species of Premna, has been confused by- 

 several authors with plate 13 U. The first reduction of Gumira 

 laut was by Linnaeus in the original publication of his Premna 

 integrifolia, Mant. 2 (1771) 252, who cites Rumphius as "Folium 

 hirci Rumph. amb. 3. p. 28. 1. 134," thus originating the confusion 

 between the description of Folium, hircinum and 1. 13 % of Rumph- 

 ius, the figure cited being that of Gumira laut; t. 133 pertains 

 to Folium hircinum. However, Premna integrifolia Linn, is 

 based on Cornutia corymbosa Burm. f. Fl. Ind. (1768) 132, t. 



* Retained name, Vienna Code; Theka Adans. (1763) is older.
