crowded out by other species. Although preferably growing wildon 

 sandy sea-shores, and nearly always forming homogeneous woods, 

 it is always wanting in the Javanese Mangrove forests. The tree 

 resists direct sunlight very well, but deep shade very badly. On 

 calcareous soils and in the Javanese Teak-forests it has not vet 

 been observed wild. The species is also completely absent from the 

 mixed, shady, evergreen forests of Java. Evidently it can only main- 

 tain itself in the struggle with other species in the above-named 

 unfavourable localities

For this variety Miquel 1. c. gave i. a. the diagnosis : "amentis 

 masculis elongatis glabris : . . . vaginis 7-dentatis*" and as locality 

 "Java" (Blume !) without further detail. From the authentic material 

 found by me in the State Herbaria at Leiden and at Utrecht, the 

 following results. The number of vaginal teeth is sometimes 7, as 

 indicated by Miquel I.e. but is often also 6, and sometimes also 8. 

 The male catkins are characterized by the complete absence of hairs, 

 and by their sometimes attaining the exeptionalh great length of 40 — 50 

 millimetres. On the authentic label the locality is only indicated in 

 Blume's handwriting as: "in Javae oriental, montibus". 



A specimen found by me without further indications in the Herba- 

 rium at Leiden, which had been sent in 1867 by Tetsmann to 

 Hasskarl, and, according to a note added by Hasskahl, was derived 

 from a specimen standing in the Hortus Bogor. [in Herb. Lugd. 

 Bat. sub n. 48 (899.173)], differs so little from the above named 

 authentic specimen, that 1 suspect the authentic of C. equisetifolia 

 Forst. var. longiflora Miq. to be also derived from a cultivated 

 specimen in the Buitenzorg Gardens. Both specimens greatly resemble 

 C. equisetifolia Forst., but on account of the completely glabrous 

 male catkins they are distinctly different from the type. The number 

 of vaginal teeth in Teysmann's specimen is 7 — 8, and as in the 

 authentic specimen 6- — 8. 



I further found that not a single of the numerous other Javanese 

 specimens of Casuarina in the herbaria at Leiden and at Utrecht, 

 refer to this variety. 1 have never found the variety wild 

 in Java.
