46781 to 46787. 



From Mexico. Collected by Mr. Wilson Popenoe and presented through 

 Dr. H. J. Webber, director of the Citrus Experiment Station of the Uni- 

 versity of California. Received December 2, 1918. Quoted notes by Mr. 

 Popenoe. 



46781. Annona diyeksifolia Safford. Annonaceae. llama. 

 " Papauce. Collected at Tapachula, Chiapas, October 18, 1918. The 



tree strongly suggests Annona squamosa in appearance, but is easily dis- 

 tinguished by the leaflike bracts at the base of the branchlets. The 

 fruit is much larger than that of A. squamosa, resembling more closely 

 that of A. reticulata. It is generally heart shaped, up to 5 or 6 inches 

 in length, with the carpellary areas indicated by incised lines on the 

 surface, which is pale glaucous green in color. The skin is nearly a 

 quarter of an inch thick, the flesh is said to be tinged with rose color 

 when ripe, and the seeds are much larger than those of either A. 

 squamosa or A. reticulata."

46782. Caeica sp. Papayacese. 



" Collected at La Zacualpa, Chiapas, October 10, 1918. A wild carica 

 common in this region. It is very similar to the papaya. The plants 

 grow to a height of about 10 feet and resemble those of the papaya 

 except in the distinctly darker color of the foliage and the less deeply 

 lobed leaves. Staminate and pistillate flowers seem always to be pro- 

 duced on separate plants. The fruits are borne singly, not in clusters, 

 as is often the case in the wild papayas of Florida. They are obovoid- 

 elliptic in shape. 2 to 4 inches in length, orange-yellow in color when 

 ripe, with a more pronounced aroma than in the papaya. The natives 

 call them melocotones, or peaches. The flesh is about half an inch thick; 

 each of the numerous seeds which fill the large cavity is inclosed in a 

 translucent, whitish aril, which is the part eaten. The seeds do not 

 adhere to the wall of the seed cavity, as in the papaya, but together with 

 the arils surrounding them entirely fill the cavity. The flavor of the 

 arils is sweet and aromatic, very pleasant, and quite distinct from that 

 of the flesh of the papaya." 



46783. Chamaedoeea sp. Phoenicacese. Palm. 

 " From Pochutla, Oaxaca, August 18, 1918. This closely resembles the 



dwarf palm which I sent in from Guatemala last year under the name 

 pacayito. It is abundant on cool, shady mountain sides in the coffee dis- 

 trict above Pochutla, at altitudes of about 3,000 feet. When mature, the 

 plant has a slender trunk, perhaps half an inch thick and 2 feet high. The 

 leaves are 12 to 18 inches in length, rather finely pinnate, deep green, 

 graceful, with the rachis stiff but arching slightly. As a house plant for 

 the Northern States and for use in fern dishes it seems to me this plant 

 possesses unusual possibilities, and I strongly recommend it for trial." 



46784. Nicotiana tabacum L. Solanacese. Tobacco. 

 " From the cafetal El Progreso, near Pochutla, Oaxaca ; altitude. 2.000 



feet. Collected August 15, 1918. A pink-flowered tobacco plant, of the 

 type grown in this section of the country. It reaches a height of about 

 6 feet. I do not know that it has any particular value, but it might be
