On two Species of Gruttiferis. By Tho^mas A^'i>eksox, M.D., 

 P.L.S., Superintendent of the Eoyal Botanical ^Gardens, Cal- 

 cutta. 



Amokg many rare species cultivated in the Botanical Garden of 

 Calcutta, and of most of which specimens have escaped the devasta- 

 tion of the cyclone of the 5th October last, are two species of 

 Guttifer^ of considerable interest. The first of these, Cah/saccion 

 Siamense^ Miq. {Mammea Birmannica, mihi), was raised from 

 seed sent from Thyat Mew in Burmah, in May 1854, by Mr. E. 

 Scott, Head Gardener of the Botanical Garden. Several plants 

 were procured from this seedj and in 1863, two of them produced 

 flowers. They were then drawn, and I described them as J[/aw, 

 mea Sirmannica^ The same trees flowered again in March 1864. 

 Although one of them was seriously injured by the storm of the 

 5th of October, three specimens still exist in the Garden. 



This species was also discovered in Siam, near Bangkok, in 

 18G2, by Mr. Tejsmann, the Director of the Botanical Garden of 

 Buitenzorg, in Java; and some of the specimens collected by him 

 were sent to Professor Miquel and myself. Here these specimens 

 were recognized as belonging to my Mavimea Birmannica^ while 

 Professor Miquel described those sent to him as Calysaccion Sia^ 

 mense. Vide ^ Annales Musei botanici Lugduno-Batav.' i. p. 200. 



The two trees that flowered here have as yet produced only 

 staminiferous flowers ; and the specimens collected by Mr. Tejs- 

 mann have also flowers with stamens only. The description I 

 have given of the species therefore diff'ers from that by Professor 

 Miquel, in so far as I have been enabled to add somewhat to his 

 description from my having before me living trees of the species.
