Cordia Greggii Torr., var. Palmeri Watson. Proc. Amer. Acad. XXIV. 61, 

 Mr. Watson's varietal name can not be used, as it liaa already been given to 

 another species. We take pleasure in dedicating this species to him, as he 

 has partially pointed out the differeuce from C. Greggii, and I have no doubt 

 would have separated it at the time had the fruiting material been at baud.

 and somewhat spreading, pnberulent throughout: leaves alternate, pinnate; 

 segments linear, acute: calyx 2 lines long; sepals green, connected by scar-

Aristida bromoides H. B. K. No. 273. 



No. 167. This is 179 of Palmer's collection, also obtained by Xantus and Brandegee. 

 Its generic position is not known. 



The leaves are narrowly to broadly linear, 3 to 5 inches long, 2 to 6 lines 

 broad : fruit round and black. 



Dr. Palmer says the tree sheds its leaves just as it is ready to bloom; the 

 young ones appear at the ends of the branches as the flowers expand, and are 

 fnll grown when the fruit is ripe. At first he was of the opinion that the ahed- 

 ■ding of the leaves was caused by the trees growing in dry, rocky places, with 

 little or no soil, as these being in full bloom (probably brought on by the heavy 

 rains which had fallen a few weeks before), while those in deep soil were in 

 full leaf and had yet not shown even a flower bud. He visited Guaymas a 

 month afterward (March 15) and found the trees growing in deeper soil were 

 then in bloom and bad just dropped their leaves also; be believes, therefore, 

 that the falling of the old leaves at blooming is a natural character. 



It is surprising that a tree of such size and of such wide distribution has for 

 so long been and still remains unknown to botanists. A letter from Dr. Palmer 

 of recent date (September lUth) states that he has been nnable to get fruit of 

 this plant, the dry hot wind of June having killed the young fruit.
