170 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



(Taxodium distichum) two meters in height and a direct off- 

 spring — by seed — from its historic parent. Among other 

 things, it has the merit of being the oldest member of the 

 department. 



The Cuicateca region, consisting of the districts Cui (Cui- 

 catlan), Teo (Teotitlan), and Tu (Tuxtepec), is limited now 

 to 65 specimens of Vallesia glabra, or "Tree of the Pearls," 

 native of the Canyon of Tomellin. This small collection is 

 characterized by its exuberant growth and uniform size. Of 

 the districts which constitute this region, only Cuicatlan has 

 received a supply of plants — twenty- two different specimens 

 from Quiotepec. Among these are six plants of Bur sera 

 sucedanea from Linaloe, called "Palo Hediondo" (fetid stick) 

 by the natives of that place. 



Three districts form the Serrana region, Ix (Ixtlan), V. A. 

 (Villa Alta), and Ch (Choapain) ; only very recently I have 

 planted around these, 81 specimens of Cerocarpus fothor- 

 gylloides, a beautiful rustic little tree which is native of this 



region. 



The perimeter of the Istmica region, composed of the dis- 

 tricts J (Juchitan) and Te (Tehuantepec), was also planted 

 in a similar manner with some ,54 specimens of an arboreal 

 Pereskia, new to science, from the coast of Salina Cruz. In 

 the district of Tehuantepec I have planted 30 plants coming 

 from the same region and belonging to about a dozen species 

 in several genera — Stemmadenia, P edilanthus , Mimosa, etc., 

 and in the district of Juchitan species of several genera of 

 the Cactaceae — Opuntia, Cereus, Mamillaria, Selenicereus, 

 Echinocactus, etc. — have been planted. 



On the southern side of this department there are planted 

 40 palm-trees, species of Phoenix, about two meters high, 

 bordering a walk which bears the name of the famous Bra- 

 zilian botanist, Barbosa Rodriguos; while on the north side 

 runs another walk, five feet wide, called "Andres Cesalpmo," 

 along the edges of which we have planted 148 specimens of 

 Poinciana Conzattii Rose, brought from Tehuantepec. 



Finally I shall mention the collection of Mexican agaves
