Remarks : Description according to living material from Java, compared 

 with the herbaria in Herb Bog.-- This variety, which occurs in the Sunda 

 Archipelago especially, was called by GRIFFITH a form between the two 

 forms described by him, i. e : A. resinifera [non FORST.] Griff. == var 

 alba [Bl.] Bakh., and A. obovata GRIFF. — A. officinalis L. In inflo- 

 rescence and flowers it agrees with the var. resinifera [FORST ] BAKU.; 

 it differs, however, in the shape of the leaves.— The fruit is quite typical 

 and very small for the genus, which Rumphius had already observed in 

 his Mangium album [var. Rumphiana [HALL, f.] BAKH]. The varieties 

 „alba" and „intermedia" occur in Java, often mixed together; the var. in- 

 termedia is not only recognizable from the var. alba by the habit of the 

 trees, the shape of the leaves and the inflorescence in capitules, but also 

 distinctly by its seedlings [tab. 18). The cotyledons are reniform, and their 

 colour light green ; the base of the hypocotyl, provided with short hooked 

 hairs is not much developed ; for that reason it is seldom found in entang- 

 lements of seedlings, as is the case with the var. alba, in spite of the fact 

 that one can find the seeds of this variety drifting in large quantities in 

 the marshes, or along the beach submerged together. Besides the small 

 stems of the seedlings are green just as the first leaves, these always 

 remain small and have a striking white mid-nerve. The seedlings pictured 

 in SCHIMPER, Indo Mai. Strandfl. tab. VI 2 and 3. belong to the variety 

 intermedia. 



As a curiosity let us further remark that there are sometimes to be 

 found air-roots on Avicennia trunks (I saw this with the variety intermedia, 

 but possibly the same occurs- with other species or varieties). These air- 

 roots are very similar to the breathing-roots, except that their direction 

 is not negative-geotropic, but on the contrary they grow downwards. They 

 occur along the stems up to a height of two meters, and if the trees 

 are standing in an oblique position, one finds these roots on the lower 

 side in a row close to each other. These air-roots remain short and thus 

 do not reach the ground, but branch off. Within they are not spongy and 

 fibrous like the breathing-roots, but ligneous. I mention this case for trees 

 which stand on places where the marshes were filled up with sand, while 

 the breathing-roots were more or less buried under the ground. Probably 

 this abnormal formation of air-roots was due to the breathing, which was 

 prevented by the sand filling in the marsh.
