INDEX TO PHILIPPINE BOTANICAL LITERATURE, VI. 
By E. D. MERRILL, 
(From the Botanical Section of the Biological Laboratory, Bureau of Science, 
Mama, P. I.) 
Baker, J. G. Handbook of the Amaryllidaceae including the Alstroemerieae and 
Agaveae (1888) XII+216. 
Sixty-one genera are recognized, and all the species known to the author 
are described. Very few species are definitely credited to the Philippines, 
but several of those considered are found in the Archipelago, especially as 
introduced and cultivated plants. Indigenous and endemic species are very 
few in the Philippines. Two endemic species of Crinum are admitted, C. 
cumingii Baker and C. gracile E. Meyer; I have seen the types of both and 
consider them referable to a single species. Hurycles sylvestris Salisb. is the 
only other species definitely credited to the Philippines. 
Bargagli-Petrucci, G. Le specie de Pisonia della Regione dei Monsoni. Nuovo 
Giorn, Bot. Ital, N. 8. 8 (1901) App. 603-625, t. 4. 
Twenty-one species are recognized, of which two are definitely recorded 
from the Philippines, Pisonia excelsa Bl., and P. aculeata Linn. Several 
additional species have been found in the Archipelago, P. longirostris T. & B., 
P. alba Span. (cult.), and apparently some undescribed forms.

(minor), oligolepis (major), and polylepis Becc., OC. microcarpus Becce., 
O. dimorphacanthus Bece., and C. discolor Mart. Sixteen of the seventeen 
Philippine species are endemic, and the seventeenth (C. ornatus Bl.), Malay 
Peninsula, Sumatra, Java, and Borneo, is represented in the Philippines by 
an endemic variety.
