 in Sauvalle's catalogue, but is probal)ly not indigenous. 



Of Anacardiaceae, the mango and species of Spondias, already re- 

 ferred to as fruit trees, have also serviceable wood; much more useful, 

 however, for cabinet-work and construction is that of Rhus metopium, a 

 small to medium-sized tree abundant on the Isle of Pines. The ill- 

 famed, everywhere common guao {Comocladia dentata), which in Cuba 

 replaces the poison ivy of the United States, sometimes becomes arbor- 

 escent and twelve to fifteen feet high, with a verticil of spreading 

 branches at the top; it is, however, principally noticed here on account 

 of its virulently toxic properties. 



In closing, let us mention the many arboreal and arborescent spe- 

 cies of Coccoloha found near the seashore, and the ubiquitous mangrove, 

 silently pursuing its task of reclaiming salt marshes.

NOTES ON THE PAN-AMERICAN EXPOSITION. 



By Pauline Kaufman. 



THE horticultural display on the grounds of the Pan-American Ex- 

 position was excellent. Almost every flower that blooms was 

 shown in profusion, in its season. We were too late for the mas- 

 ses of roses, which were said to have been beautiful, but came in time 

 for the grand showing which late summer and early autumn ajffords. 

 Especially fine were the masses of canna and of cardinal flowers with 

 unusually dark red leaves. Large collections of cacti, grasses and 

 ferns were seen. Tired with sight-seeing, one had only to step out of a 

 Vjuilding and sit down to a feast of flowers. South of the Manufactures 

 building Victoria regia held court, surrounded by her satellites Nym- 

 phaea and Lotus of varying shades of x^ink and blue, yellow and white, 

 and guarded by tall rushes, sedges, and water plants of all kinds. 



In the Horticultural Imilding the plants were rather a disappoint- 

 ment, though much attention was paid to what looked like a small plan- 

 tation of pineapi)les and to the seedling cacti in their one-inch pots. 

 Forage and medicinal plants constituted the botanical exhibit of vari- 

 ous countries. Of the latter Honduras had, I think, the largest num- 

 ber. Here we were shown a thick vine, minus leaves, from which we 

 were told India rubber is obtained. The identity of this vine was 

 known only to two native gentlemen, who were not yet ready to make 

 it public. Another interesting growth was the limb of a small tree 

 which showed ou the cut ends a perfect Sm'Iss cross. This is called the
