is the richest in representation. The arid region of southern 

 Africa is well represented by the lily family in many species 

 of Aloe, Gasteria, Haworthia and Altera, and by the milk- 

 weed family in the genera Stapelia and Huernia; while the 

 great arid regions of this continent have a large representa- 

 tion in the cactus family, in numerous genera, and the ama- 

 ryllis family in the genus Agave. The stonecrop family is 

 likewise very rich in rare and interesting forms. 



To the naming and labeling of this collection of the cactus 

 family especial attention has been given during the past sum- 

 mer and fall. By far the greater part has been identified 

 and properly labeled, and all have been grouped in genera. 

 On the lower portion of the central bench in no. 5 a sequence 

 of the genera and their species has been arranged, thus much 

 increasing the value of this collection for comparative study. 

 The genus Ofamtia in house no. 6, on the side benches, has 

 been grouped, the cylindropuntias being confined to one 

 bench, and the platyopuntias, or flat-stemmed ones, to the 

 other; the relationship of species in these two groups has 

 also been indicated by placing in juxtaposition those closely 

 related. 



Much work has also been done on the orchids, in identify- 

 ing and correctly labeling such as have flowered; upon the 

 aroids and bromeliads, the latter of which are also arranged 

 to show the generic sequence, and upon many other families 

 in scattering specimens, as flowers have appeared making 

 this possible. 



Labeling, Accessioning and Herbarium. 



An average of two apprentices have been employed in this 

 department, with the addition at times of another assistant. 

 Zinc show-labels to the number of 1,961 have been manufac- 

 tured, and about 6,000 zinc data-labels. For the conserva- 

 tories 1,578 show-labels have been lettered, for trees 290, and 

 for the herbaceous grounds 294, making a total of 2,162. 



Accession numbers 10,651 to 16,867, inclusive, have been 

 registered during the year, making a total of 6,217 accessions.
