Map 5. <b> SPECIMENS EXAMINED. MYANMAR. Meiktila, Sept. 1888, <i>Collett</i> 885 (lectotype CAL photo; isolectotype K).</b> <b>HABITAT.</b> In mountain areas. <b>CONSERVATION STATUS.</b> Known only from the type collection made in September 1888. Hence, the?ata?eficient (??) category is applied to this species. <b>PHENOLOGY</b>. Flowering and fruiting September. <b>NOTES.</b> <i>Gomphostemma hemsleyanum</i> is recognised by having an axillary inflorescence, no soft hairs on leaves and is found in North Burma Keng (1969) recognised a specimen, <i>3acker</i> 8221 (BO), from East Java as <i>Gomphostemma hemsleyanum</i> probably by comparing the specimen with an illustration [<i>Ann. Roy. 3ot. Gard.</i> (<i>Calcutta</i>) 3 (1891), plate 82] from Prain’ s revision (1891). Unfortunately, this collection has not been examined. The epithet <i>hemsleyanum</i> is dedicated to Mr W. B. Hemsley who assisted Prain preparing a revision of <i>Gomphostemma</i> (Prain 1891).
