868 MINNESOTA BOTANICAL STUDIES. 



Another form which may also be placed here rather than 

 with any of the other species, is No. 2484. It grows at lower 

 elevations than the two mentioned above, and is common on 

 the wooded slopes of Hanapepe valley. It came into bloom 

 early in July. The leaves are oblong-ovate, glabrous, as in the 

 other forms, and on short petioles. The pubescence on pedun- 

 cles and calyx is scanty, and the pedicels are very short, as in 

 No. 2690. The petals have a yellow tinge, and are ciliate, but 

 the stamens are scarlet. The style is a little longer than the 

 stamens, thickened at the apex, and slightly curved. It seems 

 to be the form figured by Mrs. Sinclair, plate 2, of her illus- 

 trations of indigenous Hawaiian plants. 



Two forms from Oahu do not agree very well with any of the 

 well-marked groups, except that the shape of the leaves would 

 throw them into the lutea group. The one form, No. 2219, is a 

 small tree with smooth, light bark. The leaves are lanceolate, 

 glabrous, not conspicuously narrowed at the base, on petioles 

 of half an inch in length. There is a conspicuous intramar- 

 ginal nerve. The peduncles and calyx are hoary; petals 

 twice the length of the calyx lobes, glandular on the outside, 

 ciliate, dull red, as are the stamens; style as long as the sta- 

 mens, slightly dilated at the end. Collected on the lower 

 slopes of Konahuanui, at an elevation of 1800 feet. 



The other form, No. 2378, has a shorter, almost elliptical 

 leaf, with a tendency to contract at the base, glabrous, distinct- 

 ly veined, on very short petioles; inflorescence glabrous in old 

 specimens; fruit small, almost free, but included within the 

 calyx. Collected on the slopes of Kohuanui, at 2500 feet ele- 

 vation. A bush, with stiff, ascending branches and rather 

 crowded leaves, Fruiting specimens only were obtained. 

 Perhaps it is a form of 2219, the difference in growth and leaf 

 form being caused by the increase of elevation and the exposed 

 character of its habitat. There are no large trees at this point, 

 everything being dwarfed and stiff. 



PSIDIUM L. Sp. PI. 470. 1753. 



Psidium guajava L. Sp. PI. 470. 1753. 



The Guava is abundant in valleys and in open places in the 

 lower forest of Oahu. The largest and finest fruit was found 

 on the heights of Tantalus and Pauoa. Very few of the sweet 

 fruited bushes are found near Honolulu. On Kauai, on the con- 

 trary, bushes which bear sour fruit are rare. It is common
